Can a sphere stablely have two axes of rotation without an external input of energy?
A similar question was asked here:
Sphere rotating in several directions simultaneously?
But, based on this:
https://www.youtube.com/watch?v=_AV5JinSviE
Some of the answers appear wrong because clearly there is no single axis of rotation that the two axes of rotation can be reduced to.
Intuitively I look at that video and wonder if gyroscopic/precession would attenuate the rotation that had less energy, but maybe gyroscopic force would merely inhibit the start up of a second rotational axis, but once going there would be some conservation of momentum. Help!

This might be partially explained as ‘no’ in the section solid body rotation around 2-axes. But solid bodies still don’t consider deformation which for anything other than an object with symmetry about both axes would cause an energy loss. Possibly a bit like how one side of the moon always faces the Earth.
