This astounding robotic creature features an air suction system that enables it to walk up and down smooth surfaces like glass, plastic, whiteboards and glossy laminates. When the Geckobot's tongue hits an object in its path, the motor is triggered into reverse gear and it marches back down the wall. Geckobot's head and tail sway from side to side while it walks with an astonishingly lifelike lizard effect. A 24-page, full-color manual guides you through model building with step-by-step illustrations and fascinating scientific context. Use two AAA batteries (sold separately). Step-by-Step Assembly Video
