Strange Rotational Behavior

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.

That's ok if the moment of inertia is identical in all 3-axes. The asymmetry of MOIs gives rise to the flipping of the spin vector.
