This is an Euler's Disk

BSRsays...

I would be interested to see what would happen just before the disk stopped and suddenly there was no gravity. Even though it sounds like it's spinning faster I'm sure it's just because the edge of the disk is just closer to the mirror.

Suddenly without gravity would the energy cause the disk to rotate making it look like a ball floating in space or would it wobble and take off in one direction?

Could this even be done in space?

Are there any mathematicians in the audience tonight?

Are four questions in a row too much?

Moving this video to Mordhaus's personal queue. It failed to receive enough votes to get sifted up to the front page within 2 days.

in space? I think gravity is the primary instigator here, so in space you'd need to do this under intense acceleration or in a centrifuge to get similar results. it's just taking a really long awkward way to fall:)
