Perfect for the executive or anyone who likes high quality gizmos. This new design gives a much larger hot point allowing you to fly the top on a much larger surface area. Flying saucer look with high flying features. The advanced design includes adjustable legs for ease in leveling the device. Spin the top on the clear plastic cover. Lift it the desired height and remove the cover. The top will continue to spin in the air.

What holds the top up?

The 'antigravity' force that repels the top from the base is magnetism. Both the top and the heavy slab inside the base box are magnetized, but oppositely. Think of the base magnet with its north pole pointing up, and the top as a magnet with its north pole pointing down (fig 1). The principle is that two similar poles (e.g., two north poles) repel and that two similar poles attract, with forces that are stronger when the poles are closer. There are four magnetic forces on the top: on its north pole, repulsion from the base's north and attraction from the base's south, and on its south pole, attraction from the base's north and repulsion from the base's south. Because of the way the forces depend on distance, the north-north repulsion dominates, and the top is magnetically repelled. It hangs where this upward repulsion balances the downward force of gravity, that is, at the point of equilibrium where the total force is zero.
