I always likes gyroscopes as a kid. Do these fidget spinners have the gyroscopic affect of resistance to changing their angle of rotation? I would think they would. Anything spinning on an axis should, if it spins fast enough. I may have to get me one of these. Of course, being an engineer, I would want a finely machined one, probably costing 20x what the ones at store front counters cost. Could easily become an expensive toy!
