Abstract
A toy adapted to be immersed in water and activated by gas generated by wetted baking powder in a cavity within the toy. The toy has a pocket disposed generally above the cavity and the center of gravity of the toy. The pocket is shaped to collect gas from the cavity so that the toy rises in the water and, when the collected gas bubble reaches a sufficient size or the toy reaches the surface of the water, the toy to tip so that the bubble will escape through an orifice at an edge of the pocket which allows the toy to again sink in the water. The cycle will repeat so that the toy repeatedly rises and sinks in the water.
