ABSTRACT:
A floating body disposed within a liquid-filled container has top and bottom portions provided with extensible and retractable objects, some of which have a greater buoyancy then the body and the remainder of which tend to sink in the liquid. The body and objects have various configurations and designs which create three-dimensional changes during floating of the body each time the container is turned upside-down.
