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.

Would be better if it electrocuted the child when the wand touched the antenna.
