Toy utilizing bubbles in liquid

A toy utilizing bubbles in liquid, comprising at least one in-liquid movable member, a transparent sealed vessel adapted to contain a liquid and said in-liquid movable member, said vessel having a lower portion, an upper portion and an opening adapted to permit introduction of said liquid into said vessel, such that a volume of air will remain in the upper portion of said sealed vessel, a lid for closing said opening to seal said vessel, a bubble generating means adapted to manually introduce air into said sealed vessel through a bubble generating opening in the lower portion of said vessel thereby creating air bubbles which will ascend through said liquid, which bubbles are capable of engaging and moving said in-liquid moveable member, whereby the air from said bubbles will be collected in said volume of air remaining in the upper portion of said sealed vessel, means associated with said bubble generating opening sufficient to permit said air to pass therethrough without permitting said liquid to pass therethrough, and a means in the upper poriton of said sealed vessel sufficient to permit air to egress from said volume of air without permitting egression of said liquid, to thereby prevent an increase in pressure of said volume of air.
