Bouncing ball amusement device having reduced transparency

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, and
• the polyurethane elastomer has a density of 1.1-1.2 g/cm3 and a hardness of 70 A-90 A.
