This is the game of skill that challenges children to keep a steady hand over a robotic corkscrew course. Children simply turn the crank to power up the robot's internal dynamo, then pass a metal wand over the twists of the antenna. If the metal surfaces make contact, they complete an electronic circuit, making the android buzz and flash his lights in robotic reproof--providing all the motivation a child needs to try, try again. The robotic noggin requires no batteries or external power and has no parts that can become lost. Ages 8 and up. 9" H x 6" W x 5 1/2" D. (2 lbs.)
