The mainspring inside the robot turns gears which enable it to march forward on two legs. The race car zooms across the floor as its mainspring uncoils and turns its wheels. The countdown timer uses a more complex system of springs, gears, ratchets, and linkages to slowly tick down the seconds as it discharges — for a countdown of up to six minutes. As you assemble these models one at a time from over 130 pieces, you will learn about the inner workings of spring-powered devices like wind-up toys and ticking mechanical clocks.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eDiscover the physics concepts of potential and kinetic energy as you experiment with your spring-powered machines.
