Weird Orbit Spinning Tops

These unusual spinning tops consist of a metal disc, and an off-set sphere made from either plastic or wood. Stand the top on edge and spin it on any flat surface, and the top will sometimes spin with the sphere at the bottom, and will sometimes flip so that the sphere is at the top, like a tippe top.

The action of a tippe top does depend partly on the friction between the spinning top and the surface it is spinning on, so these tops will behave differently on different surfaces.
