ABSTRACT:
A variable-weight play ball having an inflatable inner bladder of elastomeric material disposed with a non-stretchable outer casing of flexible material to create a water region therebetween. The outer casing is provided with a valved water inlet through which water is introduced into the water region in an amount which depends on the desired weight of the ball. The inner bladder is provided with an air passage stem terminating in an air-inlet valve sealed to the outer casing and accessible from the ball exterior, thereby making it possible to blow up the inner bladder to the degree necessary to cause the water in the region to become evenly distributed therein to create a spherical water layer pressed between the bladder and the casing, the thickness of the layer determining the weight and play characteristics of the ball.
