Añadido: 2026-05-11

[00:00:00]What's up, guys? Today, we're answering a crazy question. Can a Lego car actually drive across a track made of slippery ice cubes? Let's find out.

[00:00:13]First things first, we're setting up an ultra cold ice bath, packing it completely full with ice cubes.

[00:00:30]Now, let's assemble our first contender, the power hub.

[00:00:34]It comes equipped with dual motors. The chassis has a special tall design to minimize contact with the icy surface.

[00:00:43]Connecting up the control unit and finishing it off with four wheels.

[00:00:52]Here we go.

[00:00:56]Oh no, it sank immediately.

[00:01:03]Okay, let's swap the rubber wheels for four sliding plates.

[00:01:11]Meet the paddle walker.

[00:01:16]It flipped over in the icy water, too.

[00:01:20]Next up, what's this? The steel tracks.

[00:01:24]Attaching Technic beams and support frames to the motors.

[00:01:37]Switching to four smaller, more compact wheels.

[00:01:45]Then the control unit and the key feature, tank treads.

[00:01:52]Halfway there.

[00:01:54]No way. Belly flop in the water.

[00:01:57]Update time. Let's add studs to the treads. Lightning fast. Cross the finish line. Up next, introducing the slide pad.

[00:02:09]This version features two sliding plates mounted centrally, locked in place with sturdy Technic beams.

[00:02:25]Motor and control unit installed.

[00:02:29]Ready to roll.

[00:02:33]The two plates are working, but not how we imagine. It's just stirring up ice without moving forward.

[00:02:47]Now, say hello to the Star Leg.

[00:02:54]Almost there.

[00:02:59]These extended sliding plates make a huge difference.

[00:03:04]And perfect run. The Star Leg dominates.

[00:03:09]Hit that like button and subscribe for more awesome challenges. Hey Lego fans, I'm back. Today we're tackling an epic and seriously messy challenge. Racing Lego cars through a slime pit. Which one will conquer the goo? Let's find out.

[00:03:31]First up, the crusher.

[00:03:36]Attach the dual motors.

[00:03:41]Then slap on four massive wheels.

[00:03:50]Pop the control unit and let's roll.

[00:03:58]Crusher plows through the slime like a champ. Watch the epic slow-mo replay of Total Domination.

[00:04:06]Next, the glider.

[00:04:09]This one's got two sliding plates, some connector axles and a chain link for power transmission.

[00:04:35]Don't forget the motor.

[00:04:39]Install the protective plates for the chain.

[00:04:43]Finish with the control unit and go.

[00:04:52]Uh-oh, it's crawling. And flip. Total fail.

[00:04:57]Here's another angle of the disaster.

[00:05:02]Now the twister.

[00:05:08]Double motors check.

[00:05:15]Four Lego gear wheels check.

[00:05:25]Control unit done.

[00:05:34]Hit the slime.

[00:05:36]The twister. Lightning. Fast and unstoppable. Another easy win.

[00:05:42]Introducing the blocker.

[00:05:49]Two motors.

[00:06:00]A loadbearing frame.

[00:06:07]and eight small wheels plus a chain link and the control unit.

[00:06:32]Release it.

[00:06:36]Whoa, it's swerving.

[00:06:39]Wait, it's correcting itself.

[00:06:44]Crosses the line. Success.

[00:06:47]Final contender, the stalker.

[00:06:52]Attach the motor first.

[00:07:01]Then the body.

[00:07:16]Connect the body to the sliding plates.

[00:07:28]Toss in the control unit.

[00:07:33]Time to race.

[00:07:41]The slider flipped over.

[00:07:45]It can still move, but way off track now.

[00:07:52]This isn't promising.

[00:07:57]And no surprise here. Stalker goes down in defeat.

[00:08:02]All right, folks. Welcome back. Today, we're testing a Lego vehicle's limits.

[00:08:07]Can it haul heavy cargo across a flimsy nylon bridge? Will it survive? Let's find out. First up, a nylon bridge over a 10 cm gap. Starting with the two wheels.

[00:08:20]Easy pass, no sweat.

[00:08:23]The tank rolls right over like it's nothing. Next, the two-legged walker.

[00:08:33]Smooth as butter.

[00:08:36]Now, the four wheels.

[00:08:46]Takes its time, but nails it.

[00:08:51]The black wheel doesn't even hesitate.

[00:08:56]Next challenge. 20 cm gap.

[00:09:00]Can the two wheels handle it?

[00:09:04]Yes. Nailed it.

[00:09:11][bell] How about the two-legged walker?

[00:09:18]Zips across like a champ.

[00:09:23]The tank, no problem. Four-wheel turn.

[00:09:32]Still going strong.

[00:09:35]Black wheel cleared it.

[00:09:39]But we're not done yet. Let's triple the gap.

[00:09:43]Two wheels up first.

[00:09:47]Bridge sags, but it claws its way over.

[00:09:57][bell] Now hook up the cargo trailer.

[00:10:02]Uh-oh. Chain snap.

[00:10:07]Next, the two-legged walker.

[00:10:12]Tilting bad. Almost flipping.

[00:10:17]No, it's swerving off.

[00:10:20]It's gone. Straight off the bridge.

[00:10:27]What if we had the cargo trailer?

[00:10:39]Bridge is way too slippery.

[00:10:47]It's struggling hard, but nope.

[00:11:00]Total fail.

[00:11:02]Next contender, the tank.

[00:11:05]Glides over and towels the trailer like a boss.

[00:11:09]Now, let's lord 60 g of wooden planks.

[00:11:13]Does it? Yes.

[00:11:16]120 g.

[00:11:20]Tank lops it off. [bell] 160 g.

[00:11:27]Tank crosses, but the trailer's stuck.

[00:11:36]Black wheel plays across. Zero effort.

[00:11:41]>> [bell] >> Towing a trailer, no big deal.

[00:11:46]60 g.

[00:11:49]No problem.

[00:11:52]120 g.

[00:11:54]Oops. Same issue as the tank.

[00:12:04]Last try. The four wheels.

[00:12:09]It could win, right?

[00:12:20]And success.

[00:12:23]Now attach the cargo trailer.

[00:12:32]Slow but steady. Right.

[00:12:39]Four wheels pulls it off.

[00:12:43][bell] Load 60 g of wood.

[00:12:59]Come on. You got this.

[00:13:06]Just as I expected.

[00:13:10]120 g.

[00:13:17]The car rolls slowly forward.

[00:13:28]Trailers inching up.

[00:13:31]made it. Nice.

[00:13:34]160 g.

[00:13:39]Can it handle this too?

[00:13:47]Almost there.

[00:13:51]Scores another win.

[00:13:54]Final test 200 g.

[00:14:02]Halfway.

[00:14:10]Nope. Too heavy. Four wheels gives up.

[00:14:20]Up next, I'll show you how to build all five cars.

[00:14:24]First, the two wheels. Simple design, a compact frame, and two big rubber wheels.

[00:14:45]Car number two, way bigger frame.

[00:14:57]and tank treads.

[00:15:02]Guess what? It's the tank.

[00:15:09]Which one's next?

[00:15:17]Check out these funky walking legs.

[00:15:29]Yep. It's the two-legged walker.

[00:15:36]Vehicle number four.

[00:15:48]Another large frame.

[00:15:56]Six gears plus two drive chains.

[00:16:02]Bet you know this one.

[00:16:09]Plus these grippy studded wheels.

[00:16:16]Our champion, the four wheels.

[00:16:29]Last one. Obviously, the black wheel.

[00:16:34]Those wheels are built tough.

[00:16:39]Attach the frame. Add the motor and control unit.

[00:16:45]And we're done. Thanks for watching.

[00:22:41]Oh, thanks.

[00:24:46]Heat. Heat.

[00:26:19]>> [music] >> Okay.

[00:28:25]>> [music]
