I thought "relative speed" was your cousin who drives too fast

This was an excellent miniature rendition of the full scale. Love that you're pumping out quality content, Tomato Lord

14:56 I can hear ElectroBoom screaming "THERE IS NO FREE ENERGY!"

you have to give this man respect for putting on a full fit everytime he films

Integza: I can explain it better than you Veritasium: * 4 hours later * here's another video explaining it better

Here after Derek's video about the bet. Maybe you can add some thoughts on this debate, especially considering he also made a 3D model available from his testing.

The reason your car got a 1:1 rotation between the propeller and the wheels is because your gears at the front were a different ratio. This is also why you had some issues with the first propeller not moving very much. If you do a 3:1 ratio or something it might move easier with the first propeller

I understood the explanation about halfway through because i knew dereks explanation, and thenwhen you finished the whole wind exanation i finally realised that the wind can push the vehicle up to windspeed and then the ground is moving backwards at windspeed relative to the car, allowing you to exploit thatby using gear ratios for minimal drag. Dereks old explanation, new explanation, and integza's explanation all came together for an intuitive explanation in my mind.

"3d modeling is boring" I am literally listening to the Integza video while 3d modeling

The most scientific way, that I know, of calling someone fat is telling them "Time goes slower when I'm near you", because of relativity.

I love it when the Youtubers I watch watch the Youtubers I watch, hearing about it always just gives me a little spark of joy.

I’m sure you tried your best, but by adding the fan you broke the experiment. The whole point of using a treadmill is to move the ground instead of the air, so if the car moves in the opposite direction of the treadmill it moves faster than the wind, since the air is stationary. By adding the fan, you had to make sure that the car moved faster than the wind of the fan. Unfortunately it clearly didn’t move faster than the wind of the fan. You can see this because the string attached to the frame went forward instead of backwards. So unfortunately the was too much friction in the gears or the propellor wasn’t optimal.

video idea: design and print vehicle (thats fly or just drives on the ground) which will be powered by one of yours jet engines, i'll be pleased to see that. Tomatoes are disgusting!

I'm more curious about the fact that every science youtuber has a treadmill in their house.

I've been watching the other vids on this topic and yours did indeed clear up a lot of my confusion on how the propeller, wheels and tailwind make this thing go down the road. What made it click for me was understanding that the propeller was acting as a sail as well as a propeller. Thanks.

Dude. I love every video you make. So entertaining! Thank you.

Its fun knowing that the reason this channel exist because of another YouTubers,can't wait for more chain reaction

I don't think it so much "breaks" the laws of physics as it deftly exploits them. ;)

If done right, you can accelerate the car on a treadmill with no fan or wind at all. Just the wind produced by the propeller can be enough to make the car go faster than the treadmill is spinning
