    There is a levitating top that will float above the surface of a magnet, which is stable only as long as the top is spinning. I'm not sure if that was ever made into a toy. There are also dynamically balanced magnetic levitators that rely on a sophisticated control computer to keep the object in place, but again, I'm not aware of any such things being developed into toys.

    If you have a superconductor, a powerful magnet will float above it. I saw this in our lab, when a summer student gave a demo. The downside is that you need liquid nitrogen to chill the superconductor, and the tiny rare-earth magnets only float a few mm above the surface - not too impressive.

    Finally, there is the beach ball trick. If you get a hair dryer, and blast the air upwards, you can levitate an inflatable beach ball or balloon. The ball will stay centered in the stream of air. If you got a light, painted styrofoam object, you might be able to levitate it by the same principle.
