I think you posted the wrong film. When I clicked on it,
the gyroscope was suspended by a string which someone was holding,
no "levitation" involved.

Please repost the one that shows levitation.

Learn some math, then learn some physics. One of the most
intense particle beams in the world is the SNS, being built
at OAK ridge. This will circulate 1.5x10^14 protons at
1 GeV of kinetic energy (.876c). The radius is about 40 meters.
If you plug in all the numbers, this works out to ~.005 kg-m^2/s,
of TOTAL angular momentum, far less than the spinning bicycle wheel
in your picture.

Although, in fairness, it is more than a trillion times less
than a child's top.
