ABSTRACT:
A ball having an outer chamber and a first center of volume contains an inner chamber which is substantially smaller than the outer chamber. The inner chamber has a body portion and a neck portion, the neck portion extending between the body portion and the outer skin of the outer chamber. The neck portion is the only connection between the inner and outer chambers and comprises a flexible tube for permitting the inner chamber to swing back and forth within the outer chamber about the connection. The inner chamber contains a selected amount of a medium much denser than air and when the ball is in use the ball has eccentric and unpredictable flight characteristics.
