ABSTRACT:
A variable-weight play piece, such as a ball or bat, the weight of the piece depending on the amount of water dispersed within a compressible internal body confined within a water-impermeable outer casing. The casing, whose shape is determined by the nature of the piece, is provided with a port having a removable closure, at least one section of the casing being flexible so that when manually pressed in, it acts to compress the internal body, and when pressure is released, the body then resumes its original shape which conforms to that of the casing. The internal body is formed of open-cell, flexible foam material having sponge-like properties. To impart heft to the play piece, the port is opened and pressure is applied to the flexible section of the casing to compress the internal body and thereby expel air therefrom through the open port. The pressure is then released to cause water introduced through the port to be drawn into and absorbed by the body, the port then being closed to retain the water in the play piece. To thereafter reduce the weight of the play piece, the port is opened and the internal body compressed to expel water therefrom through the open port.
