Beginner to Expert - Lego Boosters for Hot Wheels

Do you think Hot Wheels jumping should be included in the Olympic Games?😊

3:07 A pullback motor is a coiled spring. It stores energy when compressed, like a stretched rubber band. When released, the spring uncoils rapidly, transforming stored energy into motion.

Clean content, battery-free! It's incredible to see what can be made without batteries.

Not a hate comment, just an observation. In the first two jumps at the end of the video, the support is way too low for the cars to actually have a chance to jump at maximum height (especially in the first low jump). The "dangling" of the ramp makes the cars jump way lower than actually possible, compared to the last section where the support is almost all the way up to the tip of the ramp (doesn't matter that much though, because the force applied to the ramp in the x-axis is less as the car moves upwards, so the position of the supoport is okay). Maybe I'm wrong or maybe the differences wouldn't be that noticeable. Either way, I enjoyed the video! Keep it up!

3:16 Imagine a one-way street for gears! That's a ratchet and pawl. There's a wheel with teeth (the ratchet) and a little gate (the pawl). The gate only lets the wheel go one way. It's like a super cool traffic cop for gears!

The last few frames of the video are absolutely incredible!!! A stunning finale!

2:06 the car: (in slow motion) OH YEAH.

from creative idea to great video, well done bro

I love that you swapped the little guy's expressions between scenes. Super thoughtful video throughout!

the fact that no motors were used makes this so much better

Nice

For speed calculation you could use more sections than only two, for example using four instead - you gain two times more possible outcomes. If you use 6 sections that you prepared measurement accuracy grows even more.

Next videos should be about making hotwheels drive at sound speed with lego

The Pull Thruster brought a car wash to mind. :) It's a fantastic model!

3:37 the speed would increase if you put a rubber band on the front axel that speeds the car up

Reminds me of a (also) LEGO based car pusher my brother made for me when we were kids for a micro car set. These are fun!

1:32 Reciprocating motion is like a seesaw, but for machines. Imagine a piston going up and down in a car engine. That's reciprocating motion. It's basically back and forth, back and forth. Simple, right?

Cool concept! I recall a track set from about a decade ago called Turbine Twister or something like that that kind of worked like the final design in this video! That one was built into a closed loop though, so this one being a standalone booster is really cool!

This is a masterpiece.

The video is very interesting and cute, as if I returned to my childhood, looking at these mechanisms ... Super!!!🎉😘
