The Koreans used aluminum, although copper will also work.

The Hoverboard is a hoax. See the end of the video, starting at 1:41 into the video.

Think about how one would generate side forces (parallel to the floor) without friction. Without side forces, no maneuvering, starting, or stopping.

Completely different principle, but still pretty cool to play with! Picked it up at a small town gift shop a bunch of years back.
