Swimming Worm Shelf

I'm guessing magnets, but how do they work?

Those are fishing jigs, which have weights inside the plastic worm. The motor is turning that cog which is probably rotating magnets on a wheel inside the box that have alternating polarities. So when a positive comes by, it sucks the worm to the wood, and when a negative goes by it pushes it away. Its just not strong enough to throw the worm. Its just strong enough to push it into suspension.

Thats what I think at least.
