ABSTRACT:
A therapeutic resilient hand exerciser and method of manufacture is disclosed. A mass of tiny glass spheres having the consistency and appearance of a fine powder is enclosed in a resilient inner bladder which is surrounded by an outer resilient bladder and a thin layer of powder is disposed between the exterior surface of the inner bladder and interior surface of the outer bladder to prevent the surfaces from sticking together and allow relative sliding movement therebetween. The tiny spheres roll on each other upon squeezing and releasing pressure on the exerciser to provide low resistance to relative movement and allow the exerciser to be compressed quickly and to resume its natural shape quickly due to the resiliency of the superposed bladders, and thereby produces a smooth squishy sensation.
