A supermagnet cube floats between graphite disks. The cube is lifted by the ceramic magnet a few cm above it, while the two carbon disks repel the cube, keeping it stable. This small physics toy was from Dr. Martin Simon (no longer sold.) A larger version was sold by Educational Innovations: Or make your own, buy $5 pyrolytic graphite wafers from Scitoys http://tinyurl.com/8k6jm, and supermagnets from http://www.wondermagnet.com/ and http://www.supermagnetman.net/
