The Six Foot Walk On Water Ball.

This giant 6' inflatable sphere lets you walk across water as fast as you can stride thanks to hundreds of exterior inset cups that help "grip" the lake or ocean surface as you "clamber up" the sphere's interior (Play Video). With two of the fleet, buoyant spheres, opponents can race on the water, or bump and bounce the against one another harmlessly. A speed valve allows rapid inflation (electric pump sold separately) of the ball in approximately five minutes, and the sphere can be quickly and safely deflated through the same valve for easy storage and transport in the trunk of a car. The heavy-gauge PVC ball has two entrance/exit openings, and supports a single occupant up to 170 lbs. Includes rope and tie-down grommets for securing the ball to a dock. For ages 10 and up with adult supervision. Water use only; not for swimming pools. Inflated: 72" Diam. (50 lbs.)
