Beach ball

A beach ball is an inflatable ball for beach and water games and other recreation. Their large size and light weight take little effort to propel; they travel very slowly and generally must be caught with two hands, making them ideal for lazy games and for children. Their lightness and size make them difficult to use in even moderate wind. But their bright colors and ultimate portability--minus their airy filling--make them perennial favorites among both young and old.

The beach ball's invention is usually credited to Jonathon DeLonge in 1938.
