Make sports safer with foam
Woggles are useful for aquatic exercise, but they’re used for land sports too. In the following picture, a foam bar supports the ball before the kid hits it. The bar could have ruined the hit if it had been made of a more rigid material.
Other sports involving sticks and bats can also be played with water woggles, especially if there are young kids involved, who could accidentally (or on purpose, as a game) beat themselves or each other.
