ABSTRACT:
The game device includes a hollow outer ball and a small relatively heavy mass inside the ball. The mass is a flexible bladder which contains a liquid. When the ball is rolled or projected, the bladder moves around inside and changes shape so that the device travels erratically. The device is made by partially inserting the bladder into the filler opening of the outer ball, injecting liquid into the bladder through its filler passageway, which is then sealed, fully inserting the bladder into the outer ball, inflating the outer ball and sealing its filling opening.
