No table needed for Door Ping Pong! It's like a floating version of the classic game of table tennis-a super fun way for kids to engage in hours of indoor active play. Just attach the clamp to any doorway, turn the dial to adjust the length of your string, and you're ready to play ping pong without a table. The goal is to hit the ball back to your opponent every time without missing, just like in regular ping pong. Great for strengthening and enhancing hand-eye coordination, concentration, reflexes, cooperation and more. Clamp opens to a max of 9" and attaches easily to any doorframe. Tethered ball, two paddles included.
