I've seen a lot of things, but this one took my by surprise when I came across it on Youtube.
A rotating object flipping direction, appearing to violate conservation of momentum. Never saw this in school.

Irving posted this up a while back. I think it might be in the cool video thread.
ETA: It was brutal that posted this up in the video thread: https://www.ar-15.co/threads/146129-...=1#post2244529
Irving also posted it in the Post Whore Thread.
Veritasium has a bunch of cool videos. As well as Smarter Everyday, Steven Mould, Vsauce, Practical Engineering, etc.
My apologies, I didn't realize it was posted previously.
Didnt watch entire video, it is 3d, and it has X-axis Y-axis and Z-axis at Cartesian coordinates.
If ZERO force applied to 1 axis, it will just spin 1 way.

Now, if you want to talk detail mechanical/classical movement in Jupiter with much higher atmospheric pressure + You drop it from 1000 ft from top, and you try to hit a spinning racquet with tennis ball in the middle of spin, it requires 20%er. :D
No need to apologize for spreading cool stuff bub.Quote:
