The amazing ball that bounces on water. Great fun for pool, lake, river or ocean. The easiest way to have fun with a Waboba is to simply throw it so that it bounces on the water between you and a friend. Try different angles, catching it with one hand, bouncing it on waves etc. The Waboba Pro is made of polymere gel and has a polymere and elastan coating. The polymeres and the elastan surface makes the ball bounce well, and float, on water. The ball is made to endure some rough handling, but avoid bouncing it hard on ground or on walls etc.Assorted contrasting colors; sorry no choice..Designed to bounce on water only..Size: 2.3".
