The bumper balls are new. It takes 2 people to play the game and 2 bumper balls. The contestants are enclosed inside 2 transparent pods with arms and hands inside and your hands holding onto 2 handles for control. You can bump, roll, turn somersaults, and all very safely. Your head is fully protected inside the pod bubble suit and your arms and hands are inside secure and comfortable, with only your feet sticking out from the bottom. Each contestant is free to play in complete safety. Bumper balls come in 3 sizes small, medium and large and so this sport is great for everyone of all ages
