So you have seen levitation in action and want to create your own levitating toy. W. Wayt Gibbs has put together a piece to show you how to build your own levitating disco ball. This toy magnetically levitates a miniature disco ball and uses a programmable multicolor LED to create a kaleidoscopic night-light. A kit from Zeltom was needed to pull this off. For the mirror ball, a Christmas ornament was used with mirror tiles glued onto it.
