      His production team built one that keeps spinning for longer. Something to with it’s shape. It’s been a long time since I read about it.

      Sometimes it’s pretty straight forward to just do stuff for real.

        They could have made an indefinitely spinning one by sticking a ring of copper wire and running power through it while making the top magnetic, building a type of brushless motor.
