  • Patent number: 5199716
    Abstract: A ball or sphere which has suction cups distributed around its outside surface and is of a size that it can be handled and thrown in the air by hand. Generally, a ball of baseball size has been found to be the preferred size. The ball can be thrown in the air against a smooth, nonporous surface and attaches to the surface by the force of suction.The suction ball works well in adverse environments such as water in water sports and is useful for improving coordination and motor skills in throwing objects. When used in conjunction with a hand held catching surface, the suction ball can be caught by swinging the hand at the approaching ball. The ball and catching surface are particularly useful for persons who are unable to throw and catch a conventional ball.
