ABSTRACT:
A zig-zag ball useful as a toy or in sports is disclosed. The ball moves in a zig-zag manner when rolled out on a flat horizontal surface. The zig-zag movement is achieved by a mechanism placed inside the ball which alters the center of gravity of the ball as it rolls. One embodiment of the invention comprises a ball containing an internal shaft with engraved left and right threads, a hollow cylinder slideably mounted on the shaft, a weight attached to the cylinder and a pin on the cylinder contacting and following the threads on the shaft as the ball rolls and the cylinder turns on the shaft.
