Inflatable ball with predictable movements
First Claim
1. A ball, comprising:
- an inflatable inner ball partially filled with an inner ball gas and partially filled with a liquid;
an inflatable ball shell having an outer surface and an inner surface; and
an inflatable support for holding the inflatable inner ball in the center of the inflatable ball shell when the inflatable inner ball, the inflatable ball shell and the inflatable support are inflated;
wherein the inflatable support is comprised of at least three elastic spherical shells attached to the inflatable inner ball and each of the at least three elastic spherical shells has a substantially identical radius.

Abstract
A ball having an inflatable ball shell within which is found an inflatable inner ball partially filled with an inner ball gas and partially filled with a liquid that is held in the center of the inflatable ball shell by an inflatable support when the inflatable inner ball, the inflatable ball shell and the inflatable support are inflated. The ball exhibits an eccentric and unpredictable motion unless a concomitant spin is appropriately applied to it and the motion of the ball is primarily determined by movement of the liquid within the inflatable inner ball. The inflatable support can be a donut-shaped chamber having an inner radius which is substantially the same as, and may be attached to, an outer radius of the inflatable inner ball. Alternatively, the inflatable support can be three or more elastic spherical shells attached to the inflatable inner ball.
