No one understands how Skyball bounces as high as it does. And to be honest the only person in our company who understands it is our head scientist, whom we have stashed away on a desert island in the middle of the Pacific Ocean, (OK, it's Hawaii- Maui and probably some nice resort) but what we can tell you is it's not just the Helium inside that makes Skyball bounce up to 75 feet. We also know that it provides hours of fun, challenging your friends, challenging yourself, playing catch or super handball. Available in an array of cool colors (Red, Blue, Green & Purple). Skyball is one of the hottest toys of 2009.
