Abstract
A toy having a transparent hollow outer shell is formed in the shape of a surface of revolution with an axis of symmetry and contains an object visible through said shell. The object is clear of the inner surface of the shell. A flexible elastic band having spaced points of connection to the shell and located on said axis of symmetry is fixed to and supports the object between said connection points. The object's center of gravity is below said band. Rolling of the shell about its axis twists the band as the center of gravity of the object remains below the band. When the band has stored up enough energy, it untwists and spins the object first in one direction and then reversely.
