The Amazing String Thing transforms an ordinary piece of string into a magical moving rainbow nearly 3' in the air. Point it up, down, even sideways and watch as the string playfully dances in mid-air. Gently touching the string generates wave patterns and interactive shapes that seem to defy gravity. Kids can operate The Amazing String Thing while inside the custom base (directly on any table top), or they can simply take the lightweight hand-held wand wherever they go and conduct their very own string show. It requires 4 "AA" batteries, not included.
