Roro, Dodo & Kiki: How to Open a GIANT Acorn?

[00:00:08]Look everyone, there it is. Wow, it's bigger than I thought. So neat and tidy.

[00:00:13]We can do this together. Let's begin.

[00:00:16]The forest is so beautiful today.

[00:00:27]Good morning team.

[00:00:34]>> [laughter] >> Today is a great day for science.

[00:00:40]>> The summer sun gives energy to the whole forest.

[00:00:52]>> I wonder what we will discover today.

[00:00:58]Waddling onto the path.

[00:01:00]>> Waddling.

[00:01:02]>> I stopped. Quack quack quack quack quack quack quack quack.

[00:01:17]>> Science is good. Dodo.

[00:01:24]But food is also very good.

[00:01:31]Mhm.

[00:01:33]My chubby tummy is empty.

[00:01:40]It is making a funny sound.

[00:01:44]I hope our adventure has lots of yummy snacks today.

[00:01:49]>> Hi, Roro. Ready to go?

[00:01:52]>> Meow. Meow.

[00:01:55]Meow. Meow.

[00:02:11]>> Meow.

[00:02:16]>> Rooro, you are always thinking about your tummy.

[00:02:20][laughter] But food is so good. Kiki, let us enjoy the beautiful morning.

[00:02:35]The air is fresh and the flowers smell so sweet. Look, the rock.

[00:02:43]We found it. Let's climb up. Slow down, friend. Stop. Look. What is it, Dodo? Oh my.

[00:02:53]>> Over there. I see something.

[00:03:17]Hello. [laughter] I am baby lizard.

[00:03:32]I have a very fat tail.

[00:03:36]The sun makes my chubby belly feel warm and happy.

[00:03:41][laughter] I have a chubby tummy, too.

[00:03:51][laughter] We are a good match.

[00:04:21]Squeak, squeak, SQUEAK.

[00:04:30]>> Hello everybody.

[00:04:34]I am Baby Chipmunk. I love to run. Well, hello there, little friend.

[00:04:42]I love to find food. Followed by a frantic scrabbling sound on dirt and the sque. Have you seen any food?

[00:04:51]Maybe that way.

[00:04:53]I'll check over there.

[00:04:56]My chubby cheeks are empty today. Oh, no. Don't worry, little one. Not for long. Come on, everyone.

[00:05:06]>> [laughter] >> Hello baby lizard and baby chipmunk.

[00:05:12]>> We are Dodo, Roro, and Kiki.

[00:05:20]>> We are going on an adventure to find something amazing.

[00:05:25]>> And I know just the place to start our journey.

[00:05:30]Do you want to join our team?

[00:05:47]Yes, please.

[00:05:52]>> Walking is fun if we do not walk too fast. We should continue our walk. It is good for us. Oh boy. Oh boy. Oh boy. I found it. I found it.

[00:06:00]>> Yes.

[00:06:03]>> [music] >> Adventure means finding things over there. Yes, I'm sure of it. Come on, hurry. Let's go. Let's go.

[00:06:32]Ah, this shade feels so much better.

[00:06:37][laughter] Oh, what's that in the grass? LOOK.

[00:06:52]Look at that. Wow. Oh my. We found it.

[00:06:57]Yes, there it is.

[00:07:09]Wow, it's massive and perfect.

[00:07:16]Wow. Wow.

[00:07:20]>> I think it's time to gather the others.

[00:07:23][laughter] That is the biggest nut I have ever seen.

[00:07:32]Science tells us that a big nut has lots of nutrients inside. Ooh, yummy. We need to lift it. Let's go.

[00:07:43]>> Oh, wow. I can't believe how big this is.

[00:07:50]Quack.

[00:07:52]A giant acorn quack.

[00:07:56][screaming] >> That means a giant snack.

[00:08:04][laughter] My tummy is doing a happy dance.

[00:08:10]Catch me if you can. Squeak.

[00:08:14]It looks so yummy.

[00:08:21]>> [laughter] >> I want to put it in my cheeks, but it is too big.

[00:08:34]Meow.

[00:08:36]H. This acorn smells quite lovely.

[00:08:48]Meow. It smells very fresh.

[00:08:52]It will be a wonderful breakfast for all of us.

[00:09:00][screaming] Let us eat.

[00:09:10]Oh, wow. Look at the size of that thing.

[00:09:13]So big. I'm going in.

[00:09:19]M. A juicy shell. Nom. Perfect. Ouch.

[00:09:26]Are you okay, Rooro?

[00:09:30]What happened? Quack. That is not soft.

[00:09:35][laughter] But over there, that looks much better.

[00:09:40]That is very, very hard.

[00:09:46]>> [laughter] >> Let me try.

[00:10:04]Squeak. Ouch. That's no good.

[00:10:08]Sleepy lizard can help.

[00:10:17]My teeth cannot break it. The shell is like a rock and it's too shiny. Why did it have to be so big? I can't move it.

[00:10:39]I am strong.

[00:10:44]I will use my fat tail to crack it.

[00:11:16]H. What's this?

[00:11:21]Is this my tail?

[00:11:27]Oh, that did not work.

[00:11:31]The nut is harder than my tail.

[00:11:37]I can help.

[00:11:48]Meow. The shell is perfectly smooth and thick.

[00:11:55]We cannot open it with our beaks, teeth, or tails.

[00:12:04]We are locked out of our breakfast.

[00:12:09]>> We'll figure it out together.

[00:12:13]Quack. This is a sad adventure.

[00:12:17]Don't worry, little one. I'll help you up.

[00:12:20]We have the biggest, yummiest snack in the forest.

[00:12:31]But we cannot eat it.

[00:12:37][gasps] My tummy is crying.

[00:12:47]My chubby cheeks will stay empty forever.

[00:12:52][laughter] All right, team. I've got a plan. We can get this acorn home.

[00:13:01]I've got it. I know how to move the giant acorn.

[00:13:08]Do not worry team. Worry team.

[00:13:20]>> We are not giving up.

[00:13:24]If our teeth and tails cannot open the nut, then perhaps we need a different approach. I have an idea.

[00:13:32]We will use our brains to figure it out.

[00:13:35]>> We'll use our brains.

[00:13:36]>> Use our brains. Yes.

[00:13:38]>> Yes, we will use science.

[00:13:45]>> We will use science.

[00:13:52]We need a simple machine.

[00:14:00][music] A simple machine.

[00:14:03]Huh?

[00:14:04][laughter] Yes.

[00:14:09]We will build a wedge.

[00:14:12]>> A wedge is a tool that can split hard things apart. See how my paws make a triangle?

[00:14:20]Let's get to work and open this giant breakfast. Listen, team. Quack. Quack.

[00:14:25]>> Meow.

[00:14:28]Croak.

[00:14:29]Chirp chirp.

[00:14:31]>> When we cannot pull something apart, we must push it apart.

[00:14:38][laughter] Science gives us a simple machine called a wedge.

[00:14:49]A wedge is thick on one side and very thin on the other side.

[00:14:55]>> The thin side goes into the hard shell just like this. We swing it and crack.

[00:15:03]>> Then we hit the thick side.

[00:15:09]>> That's the plan. The wedge pushes the shell apart. That's so cool. Oh, that makes sense.

[00:15:20]Quack, that sounds like magic.

[00:15:29]It is not magic, Roro. Oh, okay. Just physics. Physics. H, it is physics. Mhm.

[00:15:44]But where do we find a wedge in the forest?

[00:15:48]Perhaps we can use something else.

[00:15:51]>> We need a rock. 1 2 3. Let's find it.

[00:15:59]>> We need a special rock that can balance on one point but has a smooth surface.

[00:16:07]It must be flat with one very sharp edge and one flat edge.

[00:16:15]>> We also need a hammer and maybe a big net.

[00:16:23]A hammer is something heavy to hit the rock.

[00:16:28]Squeak.

[00:16:31]Squeak. I am fast. We'll need you, Speedy. Look, it's him. I am here friends. I will find the sharp rock.

[00:16:45][gasps] Zoom.

[00:16:59]>> Is he in there? SQUEAK. SQUEAK. GET OUT.

[00:17:02]>> OH, there he goes.

[00:17:06]I am slow, but I am strong.

[00:17:16]I will find a heavy hammer.

[00:17:29]Look, they're here finally. Shh. They are coming out.

[00:17:38][screaming] I found it. I found it. Look, DODO.

[00:17:48]ROORO, you found it.

[00:17:53]Look at the edges. So thin.

[00:17:59]All right, team. It's time to test this.

[00:18:07]Perfect. [laughter] [applause] That is a beautiful wedge, baby chipmunk.

[00:18:35]>> [groaning] [snorts] >> Here is the hammer.

[00:18:51]It is very heavy. It made me tired. I need to rest my fat tail now.

[00:19:09]Thank you, baby lizard.

[00:19:14]>> Meow. We have all the parts.

[00:19:23]Let us build our machine.

[00:19:37]Okay. Roro ready. Dodo.

[00:19:44]Hold the rock straight.

[00:19:48]Then we move back this way.

[00:19:53]I will use the heavy branch to hit it.

[00:19:58]Waddles push. Oh no, it's slipping. Be careful.

[00:20:26]We need to try again. It didn't work.

[00:20:29]It's getting away.

[00:20:34]Oh, it's getting away. Don't worry.

[00:20:37]We'll get it. Meow. OH. [screaming] OH, NO. WAIT. Got it. Phew.

[00:20:51]Almost there. I'm going to get you. Here I go.

[00:21:05][panting] The giant breakfast is trying to run away.

[00:21:18]>> Mow.

[00:21:23]A round acorn will always roll.

[00:21:28]We cannot hit the wedge if the acorn is moving.

[00:21:35]We need a base to hold it steady.

[00:21:38]>> That's it, the giant acorn.

[00:21:40]>> But how do we move it up?

[00:21:45]Good thinking, Kiki.

[00:21:57]Let's make a dirt ring. Got to dig fast.

[00:22:00]Got to dig fast.

[00:22:04]Where is it? It's here somewhere.

[00:22:19]Look at it turn into mud. We did it.

[00:22:27]>> Perfect. This spot looks ideal.

[00:22:33]>> H heave. Push. Push. Almost there. Yes, we did it.

[00:22:47]Science problem solved. Look, >> now the acorn is steady. Who wants to swing the heavy hammer? Quack.

[00:23:08]Meow.

[00:23:09]Squeak. Me, me, me.

[00:23:15]Look at me. Watch this. Taa.

[00:23:20][screaming] [crying] I have lots of energy.

[00:23:29]Can't move it.

[00:23:31]Just a little. Almost.

[00:23:35]H N G H N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N G Squeak, [crying] the hammer is too heavy for a chipmunk.

[00:23:56]It's okay. We can do this together.

[00:24:01]>> Quack. Let me try.

[00:24:05]Quack, quack.

[00:24:10]H. Come on. Just a little more. I can do it.

[00:24:19]I can't hold it. I can. Here goes nothing.

[00:24:24][screaming] >> Oh my. That was close. What was that?

[00:24:35]Wow. Look at the size of that. That's a big stick.

[00:24:41]Wa wa wa wa.

[00:24:45]Oh, wow. Goodness.

[00:24:52]Quack. I am not a good builder.

[00:24:56]My wings are too soft. It's okay, Rooro.

[00:24:59]We can still do it. Really? Yes.

[00:25:02]Together. Meow. I am agile.

[00:25:07][snorts] >> God. But I do not want to get my clean paws dirty.

[00:25:19]The hammer is too messy.

[00:25:23]We need a better tool. Let's think.

[00:25:35]I can lift it, but I cannot swing it hard enough to crack this giant shell.

[00:25:40]Oh no, Dodo. That's terrible.

[00:25:44]We need a lot of force.

[00:25:48][laughter] Force is mass multiplied by acceleration.

[00:25:56]H.

[00:25:57]>> We have to get this right.

[00:25:59]>> We need something very heavy and very fast.

[00:26:02]>> Heavy and fast. Okay.

[00:26:04]>> Yes. A heavy fast thing.

[00:26:08]>> H I have an idea. My tail and the branch. I can do this.

[00:26:17][clears throat] >> I have an idea.

[00:26:23]My tail is very heavy, but I can use it to help us carry the giant acorn home.

[00:26:33]My tail is very strong.

[00:26:42]I can swing my tail very fast. Yes.

[00:26:50]Yes. Maybe we can use the rock.

[00:26:54]Let's do it. Baby lizard, you are a genius. H Come on, let's go. We have an adventure waiting.

[00:27:07]>> With your strong tail, we can swing this hammer.

[00:27:14]>> Perfect. Nice find, Kiki.

[00:27:17]We can use this. They're all secure.

[00:27:22]You're so clever, Dodo.

[00:27:25]Is it time to eat yet?

[00:27:29][laughter] >> Wow, baby lizard looks like a dinosaur now. [laughter] A cute chubby dinosaur.

[00:27:48]Are you ready, baby lizard? Yes, Dodo.

[00:27:51]Ready.

[00:27:57]I am ready. Jump.

[00:28:03]>> Okay team. 1 2 3. Let's do this.

[00:28:07]One, two, three. Here we go. That's it.

[00:28:10]Let's go. One. [screaming] two three science.

[00:28:40]Here we go.

[00:29:15]Look, it's splitting. Wow, it's so beautiful. We did it.

[00:29:35]Wa! Delicious jump. [screaming] [laughter] We did it.

[00:29:48]The wedge worked. The simple machine worked.

[00:29:54][laughter] Hooray for science.

[00:30:03]Hooray for baby lizard's fat tail.

[00:30:06]>> [laughter] >> Thank you, baby lizard.

[00:30:10]You're welcome.

[00:30:19]Meow. It is finally time for breakfast.

[00:30:33]Yum. Yum.

[00:30:40]It is so soft and sweet. Squeak.

[00:30:46]Food. Food. Food.

[00:30:59]Meow.

[00:31:01]It is delicious.

[00:31:10]M.

[00:31:11]This is very good. It gives me energy. I think I know what we can do with these.

[00:31:18]H. What is it, Dodo? Look at these shells. They're perfect.

[00:31:25]Uh, look at these shells, team.

[00:31:31]They are perfectly round.

[00:31:34]They are very thick. We can use them.

[00:31:41]Can we eat them too?

[00:31:44][laughter] No, Roro. We cannot eat wood. [laughter] We're heading for the stream, remember?

[00:31:55]But we can use them to float. They are perfect little boats.

[00:31:59]>> Boats. Boats.

[00:32:03]All right, team. Push. Heaveho. We're doing it.

[00:32:07]>> Everyone on board. Let's go.

[00:32:09]>> Hooray. Adventure awaits.

[00:32:11]>> I am the captain.

[00:32:15]>> Ah, nice.

[00:32:19]>> The shape of the shell pushes the water away. This is buoyancy.

[00:32:23]>> Oh, buoyancy. Meow.

[00:32:25]>> Buoyancy. That's it. We used a simple machine, but a simple machine is nothing without a great team. Quack, meow, hiss, squeak. When we work together, we can crack any hard problem. We can do this.

[00:32:43]>> Yay! We did it. Hooray! We made it.

[00:32:46]We're home. The end of the giant summer acorn adventure.
