Abstract: A randomly deflatable balloon having a nozzle, and an insertable lightweight ball that can become lodged in the nozzle, thereby forming a ball check valve. The lightweight ball is preferably made from expanded polystyrene foam. The balloon is inflated after the ball is inserted into the balloon. When the nozzle is released to allow air to escape from the balloon, the ball eventually gets trapped in the nozzle of the balloon, thereby blocking the outflow of air. The ball can be dislodged from the nozzle by tapping the balloon, which causes the balloon to rocket through the air until the ball gets trapped again in the nozzle, whereupon the balloon stops moving due to escaping air, and then drops to the ground, partially deflated. This can be repeated until the balloon is completely deflated. The random partial deflation can be the basis of both solitary and multiplayer games.
