INSIDE THE BODY l Earth to Luna

[00:00:00]La Luna Luna Luna la.

[00:00:08]The questions and adventures never end.

[00:00:11]How do lights turn on? Where have dinosaurs gone? Can the wind sing a song? Are they really black swans? Why do people yawn where the stars at dawn?

[00:00:20]The questions and adventures never end.

[00:00:31]floating along.

[00:00:36]>> There it is. The Dead Sea.

[00:00:39]>> The Dead Sea? Like dead? What happened to it?

[00:00:45]>> Nothing happened to it. That's just its name.

[00:00:49]>> H. You probably don't remember this place, huh, Luna?

[00:00:52]>> Remember?

[00:00:54]I've been here before. Sure. We brought you here when you were a little baby.

[00:01:00]>> Really?

[00:01:01]>> Yeah. See? A >> You were so cute.

[00:01:05]>> Wow. But it looks different. Like there's less water.

[00:01:11]>> H.

[00:01:12]>> That's because there is. The Dead Sea is disappearing.

[00:01:16]>> Disappearing?

[00:01:18]>> That's what Sarah and I are here to research.

[00:01:21]>> But there's still plenty for a good swim in the Dead Sea.

[00:01:24]>> Yay.

[00:01:27]Come on, Jupiter. But my floaties, Daddy, I need my floaties.

[00:01:33]>> You won't need them here, Jupiter.

[00:01:36]>> Then how am I going to swim?

[00:01:38]>> This water is very special.

[00:01:42]>> But I don't even know how to float.

[00:01:46][laughter] >> You'll be able to float here. You'll see.

[00:01:51]>> I'm floating.

[00:01:53]I'm doing it.

[00:01:56]Yeah, it is really easy to float here.

[00:02:00]>> Look at me. No arms.

[00:02:04][laughter] >> Well, we better head out and rinse all this dead sea water off.

[00:02:12]>> Luna, did you see? I floated all by myself.

[00:02:17]>> See? Special water. H >> I wonder if that's why it's easy to float here.

[00:02:24]Is the water here really different? What is the Dead Sea? What's happening here?

[00:02:35]What's happening here? What can it mean?

[00:02:40]This is the greatest thing I've ever seen. What's happening here? Let's figure it out. I just got to know what this is all about.

[00:02:56]>> The Dead Sea is so much fun. You can float without floaties.

[00:03:02][laughter] >> That's right. But why is it so easy to float?

[00:03:07]>> Maybe. Maybe. I swallow lots of air and so I'm just like a floaty after dad blows it up. [laughter] >> Maybe.

[00:03:18]But dad said the water was special here.

[00:03:21]>> Yeah. My mom says the Dead Sea is really special.

[00:03:29]>> I know. Scientist Jupiter, scientist Clyde, scientist Rachel, grab your buckets. It's experiment time.

[00:03:39]>> Yay.

[00:03:41]>> We'll need a bucket of water from the Dead Sea and a bucket of normal water from the showers.

[00:03:48]Now what? Now Mr. Rex is going to help us test out the waters.

[00:03:54]>> Let's try the normal water first and see if he can float.

[00:03:59]>> Oh, poor Mr. Rex.

[00:04:02]>> Now, let's see if he can float in the dead sea water.

[00:04:08]It worked.

[00:04:09]>> No, didn't.

[00:04:10]>> But why?

[00:04:13]I don't see any differences in the waters. Do you?

[00:04:17]>> I don't.

[00:04:18]>> Me neither.

[00:04:20]>> Maybe we just need a better look.

[00:04:27]>> I don't see anything different.

[00:04:29]>> Rachel, are you ready to go >> now? But we're in the middle of a scientific investigation.

[00:04:37]>> Yeah. Your dad is making your favorite lunch. We can't be late.

[00:04:41]>> Oh, yeah. I forgot. Make sure to tell me what you find out. Okay, bye Rachel. Oh, Jupiter, what are you doing?

[00:04:51]>> I wanted to see which one was heavier.

[00:04:54]>> And they're the same.

[00:04:58]>> Oh, let's make believe we're little fishies that live in the Dead Sea. Then we can find out everything about it.

[00:05:08]>> Yeah.

[00:05:14]We are.

[00:05:15]>> Huh? What are we? I don't think we're fish.

[00:05:19]>> Did we mess up the make believe?

[00:05:21]>> I don't think so. But I've never seen fish that look like this before.

[00:05:26]>> This place is strange, too. There's no plants or anything.

[00:05:31]>> You're right. How strange.

[00:05:37]>> Jupiter water tastes funny.

[00:05:42]Wow, it's really, really, really salty.

[00:05:47]Yeah, it's saltier than the ocean. A lot saltier.

[00:05:52]>> Hey, did you see that? He looks just like us.

[00:05:56]>> Let's go talk to him.

[00:05:59]Hey, sir.

[00:06:00]>> Huh?

[00:06:01]>> Hey, what type of fish are you?

[00:06:03]>> What? It's just that. Well, we've never seen fish that look like you before. Or us.

[00:06:10]>> Fish? I'm not a fish. Just imagine fish in the Dead Sea. Huh? We're bacteria.

[00:06:18]>> Bacteria.

[00:06:19]>> You mean we're little itty bitty bacteria?

[00:06:23]>> Well, yeah. You guys must be new around here.

[00:06:27]>> Yeah. And we're really confused.

[00:06:29]>> Well, follow me. I'll show you around.

[00:06:32]>> Thanks. Over there is some water.

[00:06:37]More water over here.

[00:06:40]>> And there's some more water right over there. And there there is an absolute best swimming spot.

[00:06:48]>> Oh, very nice.

[00:06:52]>> There's not really much around here, is there?

[00:06:57]>> Hey guys, >> these are my friends. They're microbes, too.

[00:07:03]>> Gee, seems like all there is here are microbes and water.

[00:07:08]>> Well, yeah. We're the only ones who like water that's this salty.

[00:07:12]>> I get it. That's why it's called the Dead Sea. Cuz nothing lives here.

[00:07:18]>> Nothing. What about us?

[00:07:21]>> Except for microbes. That is [laughter] >> rivers and lakes flow [singing] to the sea. But that's not the case with the Dead Sea.

[00:07:34]Rivers [music] and lakes flow out to the sea. But that's not the case with the Dead Sea.

[00:07:41]>> Water comes in, but it can blow [music] out.

[00:07:44]>> It can only evaporate. [singing] >> Evaporate.

[00:07:47]>> Living behind salt and minerals, >> making salty water. It's so [music] great.

[00:07:55]>> And lakes flow out to the sea. But that's not the case with the Dead Sea.

[00:08:01]Rivers and lakes flow out to the sea.

[00:08:04]But that's not the case with the sea.

[00:08:07]Salty water, no need for a boat. Salty, salty water [music] makes it easy to float. Salty water, no need for a boat.

[00:08:17]Salty, salty water makes it easy to float.

[00:08:22]>> This is the best experience ever.

[00:08:26][laughter] So, water flows into the Dead Sea but can't flow out.

[00:08:33]>> But it evaporates and leaves behind salt and minerals.

[00:08:38]And that's why it's so salty.

[00:08:41]>> Yeah. And there's so much salt, it's like it holds you up in the water.

[00:08:46]>> You got it. And it gets saltier every day.

[00:08:50]>> Amazing.

[00:08:54]>> Hey, you splashed me.

[00:08:59]Gotcha.

[00:09:01][laughter] Gotcha.

[00:09:05]>> What are you guys doing?

[00:09:07]>> We're micro.

[00:09:09][laughter] >> Oh, okay. And did you find out what's so special about this dead sea water?

[00:09:16]>> We did.

[00:09:17]>> Yeah. Well, you'll have to wait for our Dead Sea show to hear all about it.

[00:09:25]Do you know what's so special about the Dead Sea?

[00:09:29]>> It's really pretty. [laughter] >> Well, yeah, but there's more.

[00:09:35][music] >> Rivers and lakes flow out to the sea, but that's not the case with the Dead Sea.

[00:09:48]Rivers and lakes out to the sea, but that's not the case with the Dead Sea.

[00:09:54]Water comes in but it can't blow out.

[00:09:56]>> Blow out.

[00:09:57]>> It can only evaporate evaporate.

[00:10:00]>> Living behind salt and minerals minerals making salty water. It's so great.

[00:10:08]Rivers and lakes flow out to the sea.

[00:10:11]But that's not the case with the sea.

[00:10:14]Rivers and lakes flow out to the sea.

[00:10:17]But that's not the case with the sea.

[00:10:20]Salty water, no need for a boat. Salty, salty water [music] makes it easy to float. Salty watertight.

[00:10:35][cheering] >> That was fantastic.

[00:10:40]>> That's amazing. I had no idea.

[00:10:45]>> Oh no, I'm all wet.

[00:10:48]H I wonder why the water is blue and why the sky is blue but the clouds are white. Uh so many questions la.

[00:11:13][music] The questions and adventures never end.

[00:11:16]How do lights turn on? [music] Where have dinosaurs gone? Can the wind sing a song? Are there really black swan? Why do people yawn? Where the [music] stars at? The questions and adventures never end.

[00:11:30][music] Earth to Luna.

[00:11:36]>> Healing powers.

[00:11:43][laughter] a tie.

[00:11:48]Let's go again.

[00:11:51]>> Okay.

[00:11:53]>> Ready?

[00:11:54]>> Mhm.

[00:11:55]>> Mhm.

[00:11:55]>> Steady. Go.

[00:11:58][laughter] >> I won. I won.

[00:12:08]Huh? Ka, what happened?

[00:12:12]>> She fell and hurt her knee.

[00:12:15]It's okay. It's not so bad. See, maybe I should go and get my dad.

[00:12:21]>> Hang on. I know exactly what you need.

[00:12:25]>> Wait a second.

[00:12:27]>> Here.

[00:12:28]>> These will help you feel all better.

[00:12:31]>> Bandages? No thanks.

[00:12:33]>> These are extra special. They help fight off the ouchies.

[00:12:38]>> I don't really like bandages. They always leave a sticky mess and hurt to take off. You don't like bandages?

[00:12:46]>> Uh, [crying] no. Well, we should at least clean it up.

[00:12:50]>> Yeah, you're right.

[00:12:52]>> I'll have my mom look at it. Be right back.

[00:12:56]>> But Luna, how will her knee get better if she doesn't use a bandage?

[00:13:01]>> H I don't know. How do cuts and scrapes heal anyways? Do you really need to put bandages on them? What's happening here?

[00:13:14]What's happening here? What can it mean?

[00:13:20]This is the greatest thing I've ever seen. What's happening here? Let's figure it out. I just got to know what this is all about.

[00:13:35]>> You put a bandage on it.

[00:13:36]>> My mom said I had to put one on after she cleaned it up.

[00:13:41]H very interesting.

[00:13:44]What? My parents always clean my cuts before putting bandages on, too.

[00:13:49]>> Yeah, mom and dad always clean it with water and stuff.

[00:13:54]>> So, they clean them and then put bandages on. I wonder if that's how the bandages help, by keeping the cut clean.

[00:14:03]Guys, it's experiment time.

[00:14:08]>> First, we're going to need a patient.

[00:14:13]Mr. Rex. Perfect.

[00:14:16]>> My Mr. Rex.

[00:14:17]>> Don't worry, it won't hurt a bit. And this marker washes right off, too.

[00:14:22]>> It's okay, Mr. Rex. I'm right here.

[00:14:27]>> Let's pretend he has an ouchie. Now, we just need one of those bandages.

[00:14:34]>> There. This is Mr. X's favorite. It's green, just like him.

[00:14:41]Now what?

[00:14:42]>> Now let's play. We'll check on his wound later.

[00:14:47][laughter] [laughter] All right, scientists. Let's have a look at our patient.

[00:15:13]>> Let's see.

[00:15:17]>> Yeah, his cut is still nice and clean.

[00:15:20]>> Yeah, you're right. But what does that mean? How does that make cuts better?

[00:15:26]There's only one thing to do. Make believe.

[00:15:32]>> Really? I get to do a make believe with you. Uhhuh. Woohoo. But make believe what? Well, what's something that's almost always there when you get a cut?

[00:15:47]>> Skin.

[00:15:48]>> Bandages.

[00:15:50]>> Blood. Let's make believe we're blood and figure this out.

[00:15:55]>> Blood. Neato.

[00:16:00]Okay.

[00:16:06]>> Are we blood?

[00:16:09]>> Excuse me. Excuse me. Watch out now. Red blood cell coming through.

[00:16:13]>> Oh, I get it. We're little red blood cells and we're traveling inside a vein.

[00:16:19]We help make up blood. Looks like blood is made up of all sorts of things.

[00:16:25]>> I wonder what that uh No. [screaming] >> What's happening?

[00:16:31]>> Woohoo! It's like a roller coaster.

[00:16:35][screaming] >> Hey, what's going on up there?

[00:16:44]>> Oh, [laughter] >> white blood cells.

[00:16:52]>> YEAH.

[00:16:53]>> GET THOSE INVADERS out of here.

[00:16:59]White blood cells. How interesting.

[00:17:02]>> No, Luna.

[00:17:04]>> Yeah, >> I think we have a problem.

[00:17:06]>> Oh no. [screaming] >> Platelets. Quick, seal up THAT HOLE.

[00:17:12]>> WE'VE GOT IT. COME ON.

[00:17:13]>> HURRY.

[00:17:14]>> We are losing a lot of blood.

[00:17:17][screaming] >> You can't hold on much longer.

[00:17:23]>> We need to secure that clot. Vibrant, get in there.

[00:17:31][screaming] >> Amazing. They closed up the hole.

[00:17:41]>> Everybody get moving.

[00:17:44]We need to [music] save the day.

[00:17:48]That bacteria away. We'll all keep the infection at bay.

[00:17:56]Hey, listen you. White blood cells get invaders out of here.

[00:18:02]There's infections to attack. There is nothing you [music] should fear. Now platelets go and [singing] do your job and start to [music] patch up that hole.

[00:18:12]Make sure the bleeding is under control.

[00:18:15][singing] And that is our life goal. Hey Fibon, get to work.

[00:18:20]Let's go and get the bad guys.

[00:18:23]Make a good solid clock.

[00:18:26]Trust us, we are [singing] very well.

[00:18:31]>> Everybody get moving.

[00:18:33]We need to save the day.

[00:18:37]That bacteria away.

[00:18:40]We'll all keep the infection at bay.

[00:18:45][laughter] >> That's one great looking clot. Nice and solid. It'll make a good scab. So that'll be a scab. Amazing.

[00:18:56]>> Yeah. Nothing getting in or out now.

[00:18:59]>> It's like the blood makes its very own bandage.

[00:19:03]>> You got it, buddy boy. The body is great at healing itself.

[00:19:07]>> This is the best experience ever.

[00:19:12]>> So then we don't need bandages.

[00:19:14]>> Oh, heavens to Betsy. Bandages are great. They help you from injuring the wound and reopening it.

[00:19:22]>> And they keep it clean, right?

[00:19:25]>> You betcha.

[00:19:27][laughter] >> You'll never catch me.

[00:19:30]>> Get back here, you die bacteria.

[00:19:33][laughter] >> I'll get you.

[00:19:36]>> Well, I came here to check on Ka, but it looks like everything is fine.

[00:19:42]>> You betcha. The platelets and everybody is on the job and taking care of things.

[00:19:47]And the bandage is keeping things nice and clean.

[00:19:51]>> The Wait, what?

[00:19:53]>> Don't worry, we'll have a show all about it. And you're invited.

[00:19:57]>> And Mr. Rex, too.

[00:19:59]>> Yeah, and Mom and Dad and Elsa Pascal.

[00:20:02]Everyone's invited.

[00:20:06]>> Oh, I've caught my knee. Ouch.

[00:20:11]>> Oh.

[00:20:14][music] Everybody get moving.

[00:20:20]We need [music] to save the day.

[00:20:24]That bacteria away.

[00:20:26]We'll all [music] keep the infection at bay.

[00:20:32]Hey, listen. White blood cells. Get invaders [music] out of here.

[00:20:38]There's infections to attack. There's nothing you should fear. Now platelets, [music] go and do your job and start to patch up that hole. Make sure the bleeding is under control. [music] And that [singing] is our life goal. Hey, Viper, get to work.

[00:20:56]Let's go and get the bad guys.

[00:20:59]Make a good [music] solid clock.

[00:21:02]Trust us, we are very [music] moving.

[00:21:09]We need to save the day.

[00:21:13]that bacteria away.

[00:21:16]We'll [music] all keep the infection at bay.

[00:21:22]>> Wonderful.

[00:21:24]>> Bloody terrific.

[00:21:26]>> Encore. Encore.

[00:21:28]>> Oh no.

[00:21:30]Looks like I see some bad bacteria here.

[00:21:35][laughter] H I wonder why space is so dark. It's like it's always night. Aren't there lots of stars to light it up? And how big is space anyways? Oh, so many questions.

[00:22:10]La [singing] [music] Luna Luna la. [music] The questions and adventures never end.

[00:22:21]How do lights turn on? Where have dinosaurs gone? Can the wind sing a song? Are there really black swan? Why do people yawn where the stars at dawn?

[00:22:30]The questions [music] and adventures never end.

[00:22:41]>> Traveling sounds.

[00:22:51]>> Look, there's Saurin.

[00:22:53]>> Hello, Saurin.

[00:22:54]>> Saurin.

[00:22:57]>> Hey, Saurin.

[00:22:59]Why doesn't he want to talk to us?

[00:23:01]>> How strange.

[00:23:07]>> Almost for Magic Jupiter.

[00:23:18]>> Hi Luna. Hi Clyde. Hi Jupiter.

[00:23:21]>> Not Jupiter. Magic Jupiter. the best basketball player in the solar system.

[00:23:28][laughter] >> Looks like we have a pro on the court.

[00:23:31]Speaking of pros, where's Saurin?

[00:23:34]>> Huh? I thought he was coming with you.

[00:23:36]>> Me, too. But when I rang the doorbell at his house, nobody answered.

[00:23:40]>> This is really strange, Kia. Can you believe we saw Saurin before we came over here? We called out to him and he didn't even look at us. H Do you think Saurin is upset about something? You think?

[00:23:54]>> Well, actually, I'm deaf in one ear and can only hear a little bit out of the other. And I can't find my hearing aid anywhere.

[00:24:00]>> Oh, man.

[00:24:02]>> That's why you didn't hear us earlier >> or hear the doorbell.

[00:24:05]>> And we just came in now because I noticed the door was open.

[00:24:09]>> Saurin, why didn't you ever tell us that you were deaf?

[00:24:14]>> I didn't tell you because I don't know. I guess I was embarrassed.

[00:24:19]>> Embarrassed with us. But friends tell each other everything. Which ear can I tell you a secret [music] in? When I was little, I used to pee in the bed, you know.

[00:24:31]>> Huh? Can you talk a little louder?

[00:24:33]>> I used to pee in the bed when I was little. [laughter] >> Sarin, do you have any idea where you could have lost your hearing aid? Do you think it's here in your house or somewhere else?

[00:24:45]>> I lost it here at home. I'm sure.

[00:24:47]>> Oh, okay. Well, then let's look for it.

[00:24:49]Oh, just so you know, it's really small.

[00:24:52]It fits inside my ear.

[00:25:01]>> Clyde found your hearing aid, Saurin.

[00:25:04]>> Thanks, Clyde. Thanks, Luna. Now I can hear you all. So, what was that secret, Jupiter?

[00:25:10]>> Secret? No, no, no. I don't have any secret.

[00:25:15]>> Luna, do you think it's always quiet inside Saurin's ears? Well, if he doesn't have his hearing aid, I think so.

[00:25:23]>> And he hears just like us when he has his hearing aid.

[00:25:27]>> It must be similar, but it's probably always better to talk slowly and facing Saurin when we talk to him.

[00:25:34]>> You're right, Luna. Do you think there's a piece missing in his ear?

[00:25:38]>> I don't think so, but I'm not sure.

[00:25:41]>> How do you think the ear works anyways?

[00:25:43]I know that we have something inside that makes us here. But how that thing works, I don't know.

[00:25:52]>> Huh?

[00:25:52]>> Huh?

[00:25:54]>> But don't you want to know? [laughter] >> Do I want to know how we listen? Yes.

[00:26:00]I've got to know what's happening here.

[00:26:08]What's happening here? What can it mean?

[00:26:13]This is the greatest thing I've ever seen. What's happening here? Let's figure it out. I just got to know what this is all about.

[00:26:28]Jupiter Clyde, I've just had an idea for a hearing experiment.

[00:26:33]>> Our toy ear looks awesome.

[00:26:35]>> It's perfect. Let's see if it works.

[00:26:38]Jupiter, hand me the whistle, please.

[00:26:41]>> Here.

[00:26:44]Very interesting. The sound of the whistle made the ladle move. If the inside of our ear is like that, that means >> that there's a soup ladle inside our ears.

[00:26:55]>> No, Jupiter.

[00:26:57][laughter] It just means that our ear, if it's like the one in our experiment, can feel sounds and vibrate. I wonder if vibrations help us hear.

[00:27:08]>> But how? What do you think is inside our ear? How do we hear?

[00:27:12]>> There's only one way to find out.

[00:27:15]>> How?

[00:27:16]>> We're going to make believe that we're really, really itty bitty and go inside a human ear.

[00:27:23]>> Jupiter X.

[00:27:26][laughter] >> We're itty bitty.

[00:27:29]>> Oh, Clyde, you're so so itty bitty.

[00:27:32]>> Luna, how are we going to go inside of someone's ear? And whose ear? H follow me, boys.

[00:27:44]Wa!

[00:27:45]It's so slippery.

[00:27:47]>> Yeah, the wax is helping us slide.

[00:27:51]>> Put your hands in the air and it's even more fun. Woohoo!

[00:27:55]>> Where are we going?

[00:27:57]>> Hello. Welcome to the middle ear. I'm Eard Drum. Did you all have fun sliding down the ear canal?

[00:28:06]>> So much. Can we do it again? Oh, but the fun is just beginning. Are you ready for the sound journey?

[00:28:14]>> Sound journey?

[00:28:16]>> Yes. Didn't you all want to know what's inside the ear and how you can hear?

[00:28:21]>> We do. We do.

[00:28:23]>> Well, then you have a nice trip.

[00:28:28]>> The [singing and music] outer ear.

[00:28:35]The [music] outer [singing] rear middle here. Middle here. Ear [music] drum earrum earrum.

[00:28:44]>> Let's take a trip down within.

[00:28:47]>> It's fast and about to begin.

[00:28:51]>> From the malas [singing and music] to the inus. From the gas to the [music] staves.

[00:28:57]>> From the staves right to the coia.

[00:29:04]The yellow sounds and high frequencies, low frequencies, it transforms them all.

[00:29:11]>> The auditory nerve, it works just like a lane. It sends the messages up directly to the brain. [music] [singing] >> Ear drum [singing and music] earrum.

[00:29:28]>> This is the best experience ever.

[00:29:32]We're at the brain >> and that's who interprets the sounds.

[00:29:36]>> Hey, we want to go again.

[00:29:38]>> Amazing. Sound enters through the outer ear, travels through the middle ear, and then through the inner ear, and finally to the brain.

[00:29:48]>> Yeah. But first, it goes through a ton of neat places. Ear drum. Ear drum. Ear drum. [laughter] Would [laughter] anyone like to take a little break to try Antares's new recipe? I taught it to her.

[00:30:07]>> Beautiful. Dad, >> what exactly is it?

[00:30:10]>> It's a timalo. A type of pie with pasta, egg, mozzarella, >> pie.

[00:30:18]>> Yeah, timalo.

[00:30:20]>> Himo. [laughter] Timo. Timo.

[00:30:27]I'd like a piece, too. But first, we all need to wash our hands.

[00:30:32]Well, after everyone's done eating, Jupiter Clyde and I have a really, really great show for you.

[00:30:38]>> M I'm intrigued.

[00:30:39]>> Dad, could you please save two pieces of this Timolo for our guests?

[00:30:44]>> Guests?

[00:30:45]>> Do you know what happens inside our ears when we hear?

[00:30:49]>> I have no idea, but I've got to know.

[00:30:52]I've just got to know. [laughter] [singing] The little ear [singing and music] drum [music and singing] ear drum ear.

[00:31:12]>> Let's take a trip down.

[00:31:15]>> It's fast and about to begin now.

[00:31:17][music] From the belly [singing] to the from the to [music] the from the to the pick up those sounds and high frequencies, low frequencies, [music] it all >> the auditory nerve like a lane sends a message to the brain which then interprets sound so we can hear all around the outer Ear [music] drum. Ear drum. Ear drum.

[00:31:55]>> Awesome. Well done. That was great.

[00:31:57]>> Excellent.

[00:31:58]>> It's a good thing that Clyde found your earring aid or you wouldn't have been able to hear the show.

[00:32:05]>> It's hearing aid, Jupiter. But even with it, I use a lot of lip reading to know everything you're saying.

[00:32:11]>> Do you also use sign language, Sorus?

[00:32:14]>> I do. Neato, can you teach me?

[00:32:17]>> Sure. I'll teach you something really cool and easy. Watch this.

[00:32:22]>> What did you say?

[00:32:24]>> I said hi in Romanian because that's where I learned sign language.

[00:32:29]>> Cool. You nailed it.

[00:32:31]>> There. And now you guys have to see what it was like when we went inside of the ear. It was so neat. Mom, did you know that we went in your ear and your hair smells so good?

[00:32:42]>> Wow. You've got so much to say. You're just talking nonstop.

[00:32:46]>> Talk nonstop.

[00:32:48]Just imagine how many words a person would have to say to never stop talking.

[00:32:53]I wonder if there are even enough words that you could just talk talk non-stop.

[00:32:58]Oh, so many questions.

[00:33:15]La Luna Luna la the questions [music] and adventures never end. How do lights turn on? Where have dinosaurs gone? Can the wind sing a song? Are there really black swan? Why do people yawn where the stars [music] at dawn? The questions and adventures never end.

[00:33:40][music] >> Earth to Luna.

[00:33:46]V for victory. V for vaccines.

[00:34:00]>> It's so pretty.

[00:34:09]Oh no. Luna, do you think Clyde got a virus and is sick? [snorts] >> Nothing to worry about. No virus. Clyde isn't sick. He's fine, aren't you, Clyde?

[00:34:22][laughter] >> He really is fine. Huh? But just a little while ago, he was sneezing so much. What could it have been? It must have been an allergy. Didn't you say you were doing something with flowers?

[00:34:36]You see, Clyde, you've had all your vaccines.

[00:34:40]>> Clyde has a vaccination card. Clyde, Luna, Dad, me, and you do, too.

[00:34:47]>> I do. Can I see it?

[00:34:49]>> They're right here. Something told me you were going to want to see your cards.

[00:34:53]>> I've had so many vaccines. A lot of them. I don't even remember that many.

[00:34:58][laughter] >> That's because Some of them we took when we were babies, so we don't remember.

[00:35:04]>> You have more filled in. Why have you had more vaccines than me?

[00:35:09]>> There are different vaccines that we get as we get older.

[00:35:13]>> Luna, have you had this vaccine?

[00:35:16]>> I have, Jupiter. And have you had this one? The MMR?

[00:35:22]>> The MM M what?

[00:35:25]>> MMR Jupiter. It's the vaccine that protects you from measles, mumps, and rubiola.

[00:35:32]>> I've never had MS. >> Well, thanks to the vaccine you got.

[00:35:36]>> So then when we get a vaccine for a certain type of virus, then we don't get the virus.

[00:35:42]>> Yeah, then we're protected.

[00:35:44]>> But how does a vaccine do that?

[00:35:47]>> Well, I think that that it's good question, Jupiter.

[00:35:55]I wonder how vaccines work. Now I know that I know that I don't know.

[00:36:02][laughter] I've just got to know what's happening here.

[00:36:12]What's happening here? What can it mean?

[00:36:17]This is the greatest thing I've ever seen. What's happening here? Let's figure it out. I just got to know what this is all about.

[00:36:32][laughter] >> It was a pretend vaccine, Clyde.

[00:36:37][laughter] >> Hey, did you each bring a research item?

[00:36:45]I want to see how many viruses you can find on me. [laughter] >> Is there a virus there?

[00:36:51]>> Uh-huh. And here's my idea. Let's find a virus and investigate it really close and then we can find out which vaccine is good against it. H I don't see any viruses here at all.

[00:37:07]>> There might not be any viruses, but it's so neat to see everything all big.

[00:37:13]>> Clyde, can I borrow your toy for just a minute?

[00:37:18]>> Let's investigate.

[00:37:21]I think I see something. scientist. Zoom in. Zoom in.

[00:37:27]>> I think that's just uh it's uh a piece of ferret cookie.

[00:37:33]>> H no viruses. We don't even need to try Mr. Rex. Okay.

[00:37:38]>> Yeah, Mr. Rex doesn't even look sick.

[00:37:41]But now what?

[00:37:43]>> Now we have to discover how vaccines really work. And you know how? We're going to make believe we're viruses.

[00:37:56]>> Yay!

[00:37:57]>> We're viruses.

[00:37:59]I think we're inside a human body.

[00:38:02]>> Affirmative, Clyde.

[00:38:04]>> Not quite, Luna. Farad virus. Clyde, [laughter] >> just look at how little we are.

[00:38:14]>> Look, there are other Luna viruses around. You're right. Look how many.

[00:38:20]>> It's full.

[00:38:21]>> One Luna, two three four >> Clyde. Now you're lots of Clydes, too.

[00:38:27]>> Interesting.

[00:38:29]>> I am multivirus Jupiter. Activate.

[00:38:38]>> Neato. I love bugles. Do you think the king of the human body is coming to meet us? Hate to say it, Jupiter, but that bugle call sounds more like a call to attack.

[00:38:55]>> This is amazing. Something inside the human body wants to attack us.

[00:39:01]>> And you think that's amazing?

[00:39:03]>> Huh? So, it's you. You intrusive viruses. How dare you come back here.

[00:39:08]Get out of here. AND DON'T YOU COME BACK AT ALL. You hear me? Gee, is that any way to treat guests?

[00:39:16]>> Why did you say that we came back here?

[00:39:18]Do you know us?

[00:39:20]>> Hey, of course we know you. You're the virus that came in the vaccine. There were way less of you. But that's why you're being denied entry.

[00:39:30]>> But who are you?

[00:39:31]>> We're white blood cells.

[00:39:33]We're a group of cells that protects the human body from infectious attacks.

[00:39:38]>> You are pretty efficient. But I still see plenty of our viruses around.

[00:39:44]>> That's because we're waiting for them to arrive.

[00:39:47]>> And who?

[00:39:49]>> Them. The antibodies.

[00:39:56]>> Wow. They look like superheroes.

[00:39:59]>> We're all heroes around here, but the real superhero is the immune system. Ho ho. You better prepare for battle.

[00:40:09]BATTLE >> IMMUNE SYSTEM READY AND IN POSITION.

[00:40:17]Time to get these intruders out of here.

[00:40:20]Don't worry. When the person is vaccinated, the battle doesn't last long. You'll lose in no time.

[00:40:27]>> That's encouraging.

[00:40:29]>> THIS IS THE BEST EXPERIENCE EVER.

[00:40:37]GET OUT. Virus gets bacteria. Get lost.

[00:40:42]Fungus. Shoo.

[00:40:46]Get out. Bacteria get out. Bacteria [music and singing] get up.

[00:40:54]>> If you get your vaccination [music] vaccination, then the virus can't do nothing.

[00:41:00][singing] [music] We are your antibodies here and we'll stay here. If there's action you can take, we will stay near. We'll get that illness on the go and we'll stop it.

[00:41:08]Your antibodies will fight on and we won't quit. Get out. Virus get [music] lost. Bacteria get lost. Fus get out. Bacteria get out. Bacteria get out. [music] [singing] >> We are your antibodies here and we'll stay here. If there's a vaccine you can take, we will stay here. We'll get that illus on the go and we'll stop it. Your antibodies will fight on and we won't quit.

[00:41:36]>> So that's it. Vaccines have a little of the virus in them. The white blood cells recognize them, activate the immune system and >> and get us out of there. I'm actually feeling a little tired.

[00:41:49]>> Me too. I'm not tired.

[00:41:53][screaming] [crying] >> [laughter] [laughter] >> Now for the call to attack.

[00:42:07][laughter] Now for the call to wake up now.

[00:42:14][laughter] >> Jupiter, can you play the Showtime call, please? You got it, Luna.

[00:42:22][laughter] Hi inhabitants of the space station.

[00:42:27]Today we have a very important show. But before it begins, we'd like to know >> who here has a vaccination card.

[00:42:41]>> ME.

[00:42:43]>> LET'S GO to battle.

[00:42:51]Get out. Virus, get lost. Bacteria get lost.

[00:42:58]Shoo and get lost. Get out now. Go away. Hit the road. Get gone.

[00:43:05]Shoo.

[00:43:09]>> If you get your vaccination, then the virus can't do nothing.

[00:43:16]We are your antibodies here and we'll stay here. If there's effects that you can take, we will stay near. We'll get that on us on the go and we'll stop it.

[00:43:22]Your antibodies will fight on and we won't quit. Get out. Virus get lost.

[00:43:28]Bacteria get lost. Fus and get lost. Get out now. Go [singing] away. Hit the road. Get gone.

[00:43:41]We antibodies here and we'll stay here.

[00:43:43]If there's a vac you can take, we will stay here. We'll get that illness on the go and we'll stop it. Your antibodies will fight and we won't quit.

[00:43:51]>> It's so neat learning new things. I wonder how much stuff fits in our heads.

[00:43:56]There must be so many more things for us to learn in the world, right?

[00:44:02]Oh, so many questions.

[00:44:20]Tears, tears, tears.

[00:44:29][music] 4 5 6 7 8 9 and 10. Ready or not, here I come.

[00:45:01]Ha.

[00:45:08]Clyde, you're hiding in the tree again.

[00:45:12]>> We already told you that's not fair.

[00:45:24]>> Hi, Captain Sh.

[00:45:28]>> Gotcha. Aw, captain got me caught.

[00:45:36]Hi, Grandpa. You're already cooking lunch.

[00:45:40]>> I am. It's already noon.

[00:45:42]>> Eeks. It sure is. My mom will be waiting for me.

[00:45:50]>> Oh, Captain, don't be sad. I'll be back very soon.

[00:45:56]>> Aw, poor Captain is crying.

[00:45:59]>> But he doesn't have any tears.

[00:46:02]That's just how dolls cry without any tears.

[00:46:06]>> How strange. I wonder why Captain doesn't have any tears when he cries.

[00:46:12]>> Me, too. I never really thought about it. Well, I better go. Bye, guys.

[00:46:18]>> Bye, George.

[00:46:20]>> Come back over after lunch.

[00:46:24]>> No need to cry. See, Captain.

[00:46:27]>> Huh?

[00:46:30]Grandpa, why are you crying? Don't cry, Grandpa. George will be back.

[00:46:38][laughter] >> It's nothing, guys. I'm just cutting this onion here. That's all.

[00:46:43]>> Don't be sad, Grandpa. We have lots more onions right here. Look.

[00:46:49]>> Yes, I know. [snorts] Thank you, Jupiter.

[00:46:53]>> Captain was crying, too, but he didn't have any tears.

[00:46:58]Luna, why did the onion make Grandpa sad?

[00:47:02]>> Do you think he doesn't like onions?

[00:47:05]>> Maybe he just wanted to play.

[00:47:09]>> But how exactly do we cry? What's happening here? I've just got to know.

[00:47:21]>> What's happening here? What can it mean?

[00:47:25][music] This is the greatest thing I've ever seen.

[00:47:30]What's happening here? Let's figure it out. I just [music] got to know what this is all about.

[00:47:40]>> Luna, sometimes when I yawn, a little tear comes out of my eye.

[00:47:46]>> That's true, Jupiter. And we're not even sad. And have you ever cried from laughing too hard?

[00:47:53]>> Yeah. when Clyde was dressed up like a little worm.

[00:48:00]>> So then there are different types of crying. There's sad, there's happy, there's even onion. [laughter] I wonder if you can cry on purpose.

[00:48:12]>> I think so.

[00:48:14]>> So then let's try.

[00:48:18]>> But we're not actually sad.

[00:48:20]>> Now what?

[00:48:22]>> I know. What if instead of being sad, we tried to cry from laughing too hard?

[00:48:28]>> Yay!

[00:48:30]>> Okay, so we just need to think of something really funny.

[00:48:34]>> Luna, let's have a staring contest.

[00:48:37]>> Great idea, Jupiter. That game always makes me laugh.

[00:48:45][music] Clyde, your laugh is so funny.

[00:49:06][laughter] Look, I'm crying from laughing.

[00:49:14][laughter] Me too.

[00:49:18]My tears are salty. [laughter] We did it.

[00:49:29]>> I think Clyde is upset because he doesn't have any tears.

[00:49:34]>> Ah, don't be sad, Clyde. You know, Captain doesn't have any tears either.

[00:49:40]Remember?

[00:49:43]>> And George said that's just how dogs cry. No tears.

[00:49:48]>> That's right. And he said it's normal.

[00:49:52]>> Maybe all animals cry without tears.

[00:49:55]>> But Luna, how did our eyes know that we were laughing?

[00:50:01]>> Good question. And where do tears come from?

[00:50:06]I know. Let's make believe that we're little tears and investigate up close.

[00:50:13]>> Yeah.

[00:50:18]We're tears.

[00:50:20]>> I wonder if I'm salty.

[00:50:23]>> I am. I'm salty. [laughter] >> You're right.

[00:50:29]>> But what is this place? Huh?

[00:50:32]>> I wonder if we'll get out soon.

[00:50:34]>> I don't know. Do you think we're in an eye?

[00:50:37]>> No.

[00:50:38]>> We're all waiting to see the big eye.

[00:50:41]>> Do you think it will take very long?

[00:50:44]Ah, only the eye knows these things.

[00:50:47]>> Mr. Teardrop, are you salty, too?

[00:50:51]>> Oh, yes. All of us are salty >> because of the mineral salts. We have one that is especially salty.

[00:50:58]>> Wo!

[00:51:04]>> Oh my goodness, so many tears.

[00:51:08]>> Oh, it's getting really crowded.

[00:51:10]>> Let's begin.

[00:51:12]Are we going to the eye now?

[00:51:15]>> Very, very soon.

[00:51:17]>> I'm sliding.

[00:51:18]>> Here we go.

[00:51:20]>> THE EYE.

[00:51:22]>> THE CRYING is beginning.

[00:51:24]>> But there are lots of types of crying, right? Do you know what type this is?

[00:51:29]>> I think it's from a strong emotion because there are so many of us.

[00:51:34]>> I think we're almost there. Everyone ready? Hold on tight.

[00:51:40]>> This is the experience ever.

[00:51:47]>> We're [music] just little salty [singing] tears, la.

[00:51:53]>> We're just little [singing and music] salty tears, la.

[00:51:59]>> Falling [music and singing] from your eye when you cry. But have you ever stopped to wonder why?

[00:52:07]If you're [singing] sad or hurt real bad and sometimes [music] when you're glad.

[00:52:12]>> Little old salty tears.

[00:52:16]From inside the [singing] eye and swelling out the top [music] down your cheek soon drop.

[00:52:21]>> Little old salty tears.

[00:52:25]And it won't [singing] be long till you're feeling better. Even if your face is wetter. [singing] >> Little old [music] salty tears. La.

[00:52:37]We're just [singing] little old salty tears. [music] La.

[00:52:43]We're just [singing] little old salty tears. La.

[00:52:51][laughter] Who wants some orange juice?

[00:52:59]>> Me.

[00:53:01]>> Yay.

[00:53:05]>> Grandpa, we have the best show ever for you today.

[00:53:09]>> A show? I can't wait.

[00:53:14]>> Everybody ready?

[00:53:16]>> Hi. What are you guys doing? Ready for what?

[00:53:19]>> You know, you got here just in time for the show, George.

[00:53:24]>> Yeah, perfect timing.

[00:53:25]>> Yay.

[00:53:30]We're just little old salty tears.

[00:53:36]We're just little old [music] salty tears. La have you ever stopped to wonder [singing and music] why.

[00:53:50]>> If you're sad or hurt, feel bad. And sometimes when you're glad little [music and singing] old salty tears la from inside [singing] the eye and spilling out the top down your cheek we still drop [music] >> little salty [singing] tears.

[00:54:08]>> And it won't be long till you're feeling better.

[00:54:12]>> Even when your face is wetter >> little [music] salty tears. [singing] We're just little old salty tears. La.

[00:54:22][music] >> We're just little [singing] old salty tears. La.

[00:54:30]>> Wow, Luna. You know so much.

[00:54:33]>> Excellent. [applause] Excellent. Well done.

[00:54:36]>> Look, a mama duck and her little ducklings are following her. Wow. I wonder if they're going to the lake. Why do they always walk in a line? And why are ducklings yellow if their mom is white? And are ducks born knowing [music] how to swim? Ah, so many questions.

[00:55:19]La [music] Luna Luna Luna.

[00:55:30]La Luna Luna Luna.

[00:55:36]La the questions and adventures never end.

[00:55:41]How do nights turn on? Where have dinosaurs gone? Can the wind sing a [music] song? Are there really black swans? Why do people yawn where the stars at dawn? The questions and adventures never end.

[00:55:54]La [crying] two.

[00:56:03][music] Gardening is fun. It sure is.

[00:56:29]Thank you, Clyde. You're doing an excellent job digging holes.

[00:56:36]>> Do you think they'll grow fast?

[00:56:38]>> How fast?

[00:56:41]>> By tomorrow or Saturday?

[00:56:45][laughter] >> I know, Jupiter. I don't think we'll see these flowers till next summer.

[00:56:52]>> You guys are doing an excellent job in the garden. The flowers. [music] Thank you, and so do I.

[00:57:00]Thanks, Grandma.

[00:57:01]>> And for you, >> I got a flower.

[00:57:04]>> And this one is for you, Clyde.

[00:57:08]>> Looks like Captain wants one, too.

[00:57:10][laughter] Come on, Captain. Let's pick you out a pretty little flower.

[00:57:20][laughter] >> Luna, what a funny sneeze.

[00:57:26]>> You okay, Luna? I'm okay. I was smelling my flower and it made me sneeze.

[00:57:32]>> Oh, must have been the pollen. That yellow powder in the middle of the flower.

[00:57:40]>> I want to sneeze, too. [snorts] You smelled all the pollen and now I can't sneeze.

[00:57:47]>> But why did the pollen make me sneeze?

[00:57:50]>> I wonder why we sneeze when we're not even sick. I've got to know. I've just got to know what's happening here. What can it mean?

[00:58:07]This is the greatest thing I've ever seen. [music] What's happening here? Let's figure it out. I just got to know what this is all about.

[00:58:22]>> I know. Let's investigate.

[00:58:25]Is there anything in my nose, Jupiter?

[00:58:28]>> Like boogers?

[00:58:29]>> No, like pollen. That yellow powder?

[00:58:33]>> I don't see any pollen in your nose.

[00:58:36]>> There's none now. But there was, and there can be again.

[00:58:43]I've got an idea. Let's do a super uber duper amazing experiment and sneeze again.

[00:58:52]>> What are we going to do?

[00:58:53]>> We're going to sneeze. So we can figure out why sneezes happen.

[00:58:58]I think this feather will make us sneeze a lot. needle.

[00:59:06]Hoo!

[00:59:23]Clyde sneezes funny.

[00:59:30]>> And now the pepper.

[00:59:33]A two. Your turn, Jupiter.

[00:59:36]>> A two.

[00:59:39]>> Everything is making us sneeze.

[00:59:41]Interesting.

[00:59:43]Now the flower Luna.

[00:59:51]>> A chew. Oh, wow. That was a good sneeze.

[00:59:56]>> The feather, the pepper, and the flower made us sneeze. I wonder why all these three things made us sneeze.

[01:00:05]>> I I think it's our noses that sneeze.

[01:00:09]Yeah, because something happened here inside my nose.

[01:00:13]>> It's tickling.

[01:00:14]>> H I know. Let's pretend we're all grains of pollen and fly till we find >> a flower. No, Jupiter, a nose.

[01:00:34]It's so nice and relaxing to be a grain of pollen.

[01:00:40]>> Huh?

[01:00:41]>> Look, honey bees.

[01:00:46]>> They're so big.

[01:00:49]This part of the flower is soft and it smells so good. Ah, >> yeah, Jupiter. It's pollen. That's to attract bees. [screaming] >> We got stuck to the bee's legs. Whoa.

[01:01:10][screaming] >> Look, it's Captain.

[01:01:16]>> We're going up Captain's nose.

[01:01:22]>> It's so sticky.

[01:01:25]>> That's mucus. It's what's inside noses.

[01:01:28]But get ready because the fun part is about to begin.

[01:01:32]>> The fun part?

[01:01:33]>> Yeah. Just wait until the nerve endings realize that we're here.

[01:01:38]>> Warning. Warning. Sensory nerves.

[01:01:40]Foreign particles are attempting to invade the respiratory system. Repeat.

[01:01:45]Warning. Warning.

[01:01:48]>> But we didn't evade anything. The wind brought us here. Yeah, but it looks like the wind wasn't invited and brought us along with it.

[01:01:58]>> What happens now?

[01:01:59]>> Message received. Third endings. Roger.

[01:02:02]Brain copied. Ejection system activated.

[01:02:07][crying and screaming] >> What? The nerve endings warn the brain that we're here and they're going to eject us. That's it. Amazing.

[01:02:19]>> Eject us? How? by sneezing. Clyde sneezing [screaming] a meal. This is the best experience ever.

[01:02:38]Here we go.

[01:02:46]>> That space was really, really fast. You got that right. We're faster than many cars. I mean, 150 kilometers an hour for a sneeze.

[01:02:58]That is awesome.

[01:03:00]>> So, that's it. Sneezes are like a defense. It ejects what could hurt us.

[01:03:07]>> Sneeze shield. H-bachu.

[01:03:12]P-woo.

[01:03:15]A-hu aw.

[01:03:20][singing and music] I bet you wish you knew the need for a nose. It's true. And it feels [music and singing] funny, too. A chew.

[01:03:28]H- Aw.

[01:03:33][singing] Have allergies [music] got the flu? A chew. A little pollen bothering [singing] you. A chew. That's what we grain [music] [singing] do.

[01:03:55]H- hoo hoo [singing] hoo hoo >> I want to ride another sneeze.

[01:04:12]>> I wonder what kind of nose will go up now.

[01:04:16]>> I'm a sports car and I'm a grain of pollen.

[01:04:25]Let's go again. This time I want to be the pollen.

[01:04:29]>> Ah, no, Jupiter. I'm tired of sledding.

[01:04:32]I know. Let's put on a show about sneezes for Grandpa, Grandma, and Barbara.

[01:04:40]>> Of course, Squid. And for Captain, too.

[01:04:53]Hello everybody. We and these balloons are grains of pollen.

[01:04:59]>> And today we're going to do a show about sneezes.

[01:05:03]>> Do you have any idea why we sneeze?

[01:05:06]We're going to sing all about it. Ah. A true. A a true. A a a true a a true I bet you wish you knew the need for a true queen knows it's true and it feels funny a a true a a true a a a got the flu A little pum [singing] bothering you.

[01:06:43]>> Oh no, my balloon popped again.

[01:06:48]I wonder why balloons pop and why is it so loud when they do?

[01:06:54]So many questions.

[01:07:01][music] Luna.

[01:07:04]No.
