[00:00:00]Coming up.

[00:00:09]>> [laughter] >> Watch me splash up this whole pool, BABE.

[00:00:14]>> [screaming] >> INSTEAD [groaning] OF DOING stuff like that, make this pool less boring. Hello, please help me upgrade my swimming pool. What kind of upgrade are you looking for? I want to add a second and third level to the pool. Got it. We'll start preparing the concrete [music] RIGHT NOW.

[00:00:31]I'VE BROUGHT THE CONCRETE HERE. GREAT, let's get to work.

[00:00:38]Now, I'll reinforce the second level of the pool with concrete.

[00:00:52]It's fully dry. LET'S PLACE IT ON THE FIRST LEVEL.

[00:00:57]Come on. Let's hurry and finish another level. Okay, I'll bring another batch over. All right, let's make THE SECOND BATCH OF CONCRETE.

[00:01:09]WOW, the materials have arrived already.

[00:01:13]AGGREGATES, CEMENT, SAND.

[00:01:19]NOW, pour all of them into these hoppers.

[00:01:24]Mixing tank is activated. WOW.

[00:01:34]FINAL STEP, CLOSE THE tank lid and wait.

[00:01:50]This concrete turned out pretty good.

[00:01:52]>> [laughter] >> WE CAN DELIVER THIS BATCH NOW.

[00:01:55]START POURING IT IN.

[00:01:57]>> [laughter] >> THE TRUCK IS FULL, BUDDY.

[00:02:06]ANOTHER BATCH has arrived. All right, it's time for the third level now.

[00:02:18]Nice, this one's ready to go on top, too.

[00:02:22]We only have the staircase LEFT TO FILL.

[00:02:27]>> [laughter] >> THE POOL IS ALL FINISHED.

[00:02:32]>> Thank you so much. Our pool looks way [music] cooler.

[00:02:35]>> [laughter] >> Call me if you want to build something else.

[00:02:38]>> Time to fill the pool with water and enjoy it.

[00:02:49]Wow.

[00:02:55]>> [laughter] >> What's included in the concrete mixing set? One, build the mixing tank.

[00:03:03]Rotating axle.

[00:03:05]Motor.

[00:03:07]>> [music] >> Now, I'll make the discharge outlet for concrete.

[00:03:13]Mixing paddle.

[00:03:17]The cover.

[00:03:20]Pipe connector. Two, build the hoppers.

[00:03:24]I'll build the gear drive system.

[00:03:25][music] Add the gear box.

[00:03:29]Next, I'll attach the hoppers. Pipe connector.

[00:03:34]Place them onto the base.

[00:03:37]>> In a world of beach camp, such a nice place for camping.

[00:03:41]>> [laughter] >> What a jerk.

[00:03:47]>> [groaning] >> Hey, pretty girl.

[00:03:50]>> Your car is so cool.

[00:03:55]I can't sleep here anymore.

[00:03:57]>> You can sleep in my motorhome, pretty girl.

[00:04:03]>> How modern it is.

[00:04:05]>> We don't need that, honey.

[00:04:56]My motorhome is all set up.

[00:04:59]This is so chill.

[00:05:01]I smell grilled seafood.

[00:05:06]>> Your grilled shrimp is ready, honey.

[00:05:08]>> I don't like the shrimp.

[00:05:11]>> Hey, pretty. Want to eat with me?

[00:05:14]>> Mind your businessness.

[00:05:16]>> Yes. Yes.

[00:05:18]I'm coming.

[00:05:19]>> Huh?

[00:05:20]>> This meal is such a feast.

[00:05:22]>> [laughter] >> She betrayed me.

[00:05:30]>> [screaming] >> Help me. Help me.

[00:05:32]The sea is so dangerous.

[00:05:33]>> Don't worry. My car has a pool.

[00:05:36]>> Wow, you surprised me again.

[00:05:39]>> [laughter] >> Wow.

[00:06:16]>> Wow, we should swim together.

[00:06:20]Your motor home is the best. I love it.

[00:06:24]>> Huh? This is my stolen motor home, Mr. Officer.

[00:06:28]>> I need to escape now.

[00:06:29]>> Stay right there, you thieves. You're under arrest for stealing this car.

[00:06:34]>> I'm innocent.

[00:06:36]>> Swimming pool.

[00:06:40]>> [laughter] >> Nothing fun to do here.

[00:06:46]>> I'm coming, Eva.

[00:06:50]Having fun, honey?

[00:06:51]>> This slide is boring. We had better go home.

[00:06:54]>> Wait, we're going to upgrade a special machine.

[00:06:59]The SpongeBob bubble bath toy will create tons of foam for the pool.

[00:07:03]>> [screaming] >> Wow, it looks so fun.

[00:07:09]>> [laughter] >> Now the pool will be filled with bubbles.

[00:08:45]Hoho!

[00:08:47]Wow!

[00:08:49]These bubbles are so soft. This is so relaxing.

[00:08:52]>> [laughter] >> I still have one more surprise for you.

[00:08:54]I've added a water slide to this bubble toy.

[00:08:57]Now let's enjoy this bubble slide.

[00:08:59]>> Yahoo!

[00:09:01]>> [laughter] >> Yahoo!

[00:09:06]>> [laughter] >> It's so sunny. I should go for a swim.

[00:09:25]Water!

[00:09:27]Woohoo! So refreshing.

[00:09:29]>> Yeah. Yeah.

[00:09:31]>> You fool.

[00:09:37]>> I >> [clears throat] >> Why is there no water [music] here?

[00:09:44]That silly thing.

[00:09:49]What a clown.

[00:09:54]I'll build a water pump to save my [music] pool.

[00:10:02]Almost done.

[00:10:13]This pump sucks.

[00:10:15]>> [clears throat] >> I must make a bigger and stronger pump.

[00:10:20]How to build the water pump. Step one, build the pump casing.

[00:10:29]Install the engine.

[00:10:38]Step two, build the piston.

[00:10:47]Install the battery.

[00:10:57]Install the shock absorber.

[00:11:05]Install the piston base.

[00:11:13]Step three, [music] install the water pump.

[00:11:19]Install the pump in the water tank.

[00:11:23]Testing.

[00:11:25]The piston is pushing the water up.

[00:11:28]Haha, water is being pumped up.

[00:11:31]Oh, yeah.

[00:11:34]>> Every detail is perfect. This feels great.

[00:11:43]>> Hiya.

[00:11:47]>> Let's drain all the water from his pool to mine.

[00:11:52]>> [laughter] >> Why is all the water gone?

[00:11:58]Where did this pump come from?

[00:12:03]Awesome.
