The Amazing String Thing lets children create a magical string effect of light 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. Kids can play with it on a tabletop using its own display cradle, or they can hold the lightweight unit in their hand. Measures 4 x 9 x 4.5 inches (10cm x 23cm x 11cm).
