ABSTRACT:
A variable-weight playball whose outer casing is formed of liquid-impervious, non-stretchable, flexible material, such as a resin-coated fabric, the casing being provided with a closable port. Confined within the casing is a compressible body having the same configuration which depends on whether the ball is of the spherical type or in some other shape. The body is formed of low-density, open-cell, flexible foam plastic material having sponge-like properties. To impart heft to the ball, water is introduced through the port into the body and absorbed thereby, the port then being closed to retain the water. To thereafter lighten the ball, the port is opened and the ball is squeezed to discharge water through the port until the ball has the desired reduced weight, after which the port is closed. The weight selected depends on the use to which the ball is put.
