A true wonder to watch, The Amazing String Thing transforms an ordinary piece of string into a magical moving rainbow! Creates magical string effect nearly 3-feet 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! You can operate The Amazing String Thing while inside the custom base (directly on any table top), or simply take the lightweight hand-held wand wherever you go and conduct your very own string show!
