ABSTRACT:
A swivel connection between one end of a tether and a figure having a buoyancy chamber permits the figure to rotate relative to the tether. The figure is heavier than water when the chamber is filled with water and lighter than water when the chamber is filled with gas. The tether is secured to the bottom of a water container at a point spaced along the tether from the end with the swivel connection. A plurality of holes in the figure establish communication between the chamber and the outside of the figure. Gas is supplied to the chamber at a rate alternately to cause the figure to ascend and descend. Preferably, gas is supplied to the buoyancy chamber by an air pump, which could be an aquarium air pump, through a length of flexible tube, which serves as the tether.
