The Nimble Noggin Challenge is a simple ‘steady through the wire maze’ game, no batteries required. Just a lot of patience. Not something to play with the kids the morning after the night before, perhaps. $34.95.
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.
