Almost Perpetual Motion Levitron in a Vacuum Chamber

Channel Page: Twitter: Google : mopatin Perpetual Motion Levitron in a Vacuum Bell Jar. Of course the vacuum is less than perfect and the levitation lasted less than 1 hour. Perhaps with a diffusion vacuum pump it will last a lot more. I think that the instability of the movement (precession) may create kind of tidal forces that weakens the rotation movement through magnetic induction.
