ABSTRACT:
An aerostat amusement device in the form of a ballast member including a resilient container adapted to contain a liquid such as water and having defined therein an opening sufficiently small to preclude flow of the liquid through the hole as a result of the surface tension of the liquid, but adequate to permit flow of the liquid through the hole in response to a pressure differential induced by deforming the resilient container to thus flow liquid into or out of the container in a carefully controlled manner, the ballast device being adapted to be secured to a balloon filled with buoyant gas to resemble an airship, the ballast device being accurately adjustable to maintain the balloon at a desired height by providing an equilibrium with the buoyant force generated by the balloon.
