I get the impression that it is filmed with a cammera upside down, and the top of the table is actually the bottom. A powerful magnet keeps the ball or other objects in place until it is pulled away. The object then falls by gravity 'up.'

The small movements of the objects just before 'levitating' is a dead giveaway for what happens when a magnet is pulled away. Small lateral displacements of the magnet as if a person were pulling it away results in jittery displacements of the object connected by magnetic flux-lines. The acceleration profile is unusually low at the very beginning and then rapidly approaches a steady state--exactly what you would expect from an object disconnecting from magnetic flux-lines and then falling by gravity.

I've played with a lot of magnets as a kid...

And I think this is a bunch of hooey.
