A toy object that repeatedly submerges and rises in the water, which toy is plastic molded and has a chamber for receiving baking powder and the like. The toy has a cap member integrally molded therewith and connected by a strap. The cap member serves to cover the powder chamber yet permits water to enter the powder chamber which will cause a bubble to be formed in a bubble or gas chamber on the underside of the cap, the cap also forming a holder for supporting a separately formed ballast rod in an off-center position. The toy will descend to the bottom of the water vessel and when the bubble forms in the bubble or gas chamber and enlarges it will cause the toy to ascend towards the top water level. The toy will remain at the top water level for a short period of time during the period that the bubble continues to enlarge in the bubble chamber and during this period the toy will be influenced to tip to one side due to the off-center ballast rod. After the bubble leaves the bubble chamber and breaks, the toy will straighten out and will then descend to the bottom of the water vessel. This action is repeated until the baking powder in the chamber is expended, after which it is refilled by removing the cap member. The integral formation of a toy with a cap member permits the toy to be formed of a small size, yet will pass Government safety standards in that it will not prove hazardous to small children who might try to place the toy in their mouths.
A toy object that repeatedly submerges and rises in water, comprising a body having a chamber for receiving a gas producing material, a cap having an aperture therein for sealing said chamber and providing communication between the water and said chamber through said aperture, a bubble retaining chamber for accommodating a gas bubble during the growth thereof, and a ballast longitudinally off-set of said body which in combination therewith provides an average density greater than water, whereby said toy object having a gas producing powder in said chamber sealed by said cap sinks in water until a bubble in said retaining chamber formed by coaction of water and the gas producing material is sufficiently large to cause said toy object to rise to the surface where said toy object tips to one side due to said longitudinally off-set ballast permitting the bubble to escape resulting in sinking of said toy object.
A toy object that repeatedly submerges and rises in water, comprising a body having only one chamber therein and a pivot member extending outwardly from said body, a cap having an aperture therein for sealing said chamber and providing communication between the water and said chamber through said aperture, a bubble retaining chamber separate from said body for accommodating a gas bubble during the growth thereof, and a ballast which in combination with said body provides an average density greater than water, said body and pivot member and ballast cooperating to ensure said toy object during operation thereof remains substantially submerged, whereby said toy object with a gas producing material in said chamber sealed by said cap sinks in water until a bubble in said retaining chamber formed by coaction of water and the gas producing material in said retaining chamber is sufficiently large to cause said toy object to rise until said pivot member breaks the water surface permitting said toy object to pivot about said pivot member releasing the gas bubble resulting in said toy object sinking.
