Machine Balances Bowling Ball On Rotating Spool

This is a video of a machine that was created with one job and one job only: to balance a bowling ball on a spool without it rolling off either side, constantly adjusting itself to keep the ball right on top. Not bad, but if it can’t also hula hoop and swallow a sword at the same time it has no place in my traveling circus.
