Abstract
A toy including separable base and central portions defining a cavity therebetween and a cover portion pivotably mounted on the central portion. The cover portion has a concave surface positioned over an aperture communicating with the cavity when the cover portion is in a closed position. When a chemical which will produce gas bubbles in the presence of water is placed in the cavity and the toy is dropped into a container of water, the concave surface will trap gas escaping through the aperture under the cover portion until the buoyancy of the gas moves the cover portion to an open position, allowing the accumulated gas to escape.
