Wahu Zoom Ball.

Zip it to rip it! With this high-speed action game that's safe for indoor play, players face off on either side of the Zoom Ball holding two handles. Pull the handles apart to send the ball racing full-speed toward your opponent, and don't let it hit your handles! It's super fun and a surprisingly good arm workout! For enhanced play and extra challenge, try standing on one foot, kneeling down, or changing arm movements to build strength and balance! For 2 players.
