This giant 6' inflatable sphere lets you walk across water as fast as you can stride. Hundreds of inset cups on the ball's exterior help "grip" the lake or ocean surface as you rotate from within the sphere's interior. With two of the fleet, buoyant spheres, opponents can race on the water, or bump and bounce them against each other harmlessly. A speed valve allows rapid inflation of the ball in approximately five minutes (electric pump sold separately below), 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 openings that allow safe, rapid entry and exit and let air circulate. Includes rope and tie-down grommets for securing to a dock. Supports a single occupant up to 170 lbs. For ages 10 and up with adult supervision. Water use only; not for swimming pools. Inflated: 72" Diam. (50 lbs.)
