I think a larger version of this should be called the Leviatron

Neat, even with the overindulgence of “let’s enclose this in a tube to prove there are no wires.” Two things, though. 1) It’s not antigravity 2) The blurb about torque isn’t right — it’s not that the spinning exerts a torque, it’s that the spinning means there is angular momentum. You need a torque to change angular momentum, and the torque present because of the same-facing poles is not enough to flip the top. Just like gravity exerts a torque, but cannot flip the spinning top, either.
