Don"t just play with the Pr, play like one too! With its special design, the Waboba Pro has the control to help you step up your gae! * Designed with athletes in mind, the Pro"s size and weight gives it more accuracy so you can control the bounce to other players! * Official ball for Waboba sport games. Teams and leagues welcome. * For best results, throw like skipping a rock. The harder you throw, the better it will bounce on the water. * Bounces on water only. Do not bounce on hard surfaces
