1. A ball amusement device comprising:
- an outer shell of transparent or semi-transparent elastomeric polyurethane having good bounce characteristics;
wherein the elastomeric polyurethane of the outer shell is an MDI-based polyurethane;
water within and filling the shell,wherein the ball amusement device has good bounce characteristics;
wherein the transparent or semi-transparent outer shell is configured with a roughened or textured surface to reduce the transparency to light through the ball;
wherein the composition of the polyurethane elastomer includes at least one of isocyanate, polyol, and a chain extender; and
wherein the isocyanate is a methylene diphenyl diisocyanate as part of the polyurethane elastomer,the polyol is at least one of a polyester and a polyether-type polyol with at least two functional OH groups on a molecular chain of the polyol with a molecular weight of 1,000-10,000, andthe polyurethane elastomer has a density of 1.1-1.2 g/cm3 and a hardness of 70 A-90 A.
