The very definition of "cool things with wheels" - angular momentum

watch the above only for one minute, to see the remarkable effect of force, torque, and angular momentum. Skip to 35:35 to see it on the rope, and it's interesting to about minute 39.



here, earlier in the same video, he explains it in math and physics terms.

Now... here's what I think would be cool... if an astronaut would show all this, in zero grav space, instead of playing around with water droplets, and honey twisting in a jar.
