Curious Craft Make Your Own Bouncy Balls Kit

Curious Craft® Cosmic Bouncy Balls includes everything kids need to make at least 5 bouncy balls in a variety of fun shapes. Kids simply add bouncy crystals to one of the three shaped moulds, soak in water and voila, they’re ready to bounce! The included crystals can make super-cool coloured, metallic or glow-in-the-dark bouncy balls or even an LED ball that lights up with every bounce.
