Abstract: A balloon storage and inflation assembly comprises a circular inflatable balloon containing a pair of chemical reactants separated from one another, one of the reactants being held in a burstable container. The balloon is placed between two plates of a support structure, the burstable container and a portion of the balloon being disposed in a recess formed by two aligned openings in the plates. The support structure is further provided with a pair of doors hingedly secured to respective ones of the plates along edges of the openings. The doors are swung into the openings to compress the burstable container and to facilitate a rupture thereof upon the striking of one of the doors by a fist or other object.
