A fidget spinner in space!? How long does it spin? I'm not sure, but it’s a great way to experiment with Newton’s laws of motion!

Allowing the fidget spinner to float reduces the bearing friction by permitting the rate of the central ring and outer spinner to equalize, and the whole thing spins as a unit.
