Perfect for BBQs and outdoor play, the Monster ball project provides instant fun and games. Make your own by combing an old cereal box and craft material with the bend sensor, fan, power and wire Bits. Once it’s completed, take it to your next summer gathering and try to get a ball (we like crumpled paper) into the cup below the monster’s tongue. Whenever the ball goes in, the Monster’s eye spins!
