Build an amazing motorized robot, a super - fast race car, and a precise countdown timer, all without the need for batteries or electricity! The magic lies in the mainspring, a coiled spring that stores energy when you wind it up by hand and then releases that energy to create motion. The robot marches forward on two legs as the mainspring inside turns its gears. The race car zooms across the floor as its mainspring unwinds and spins the wheels. The countdown timer has a complex setup of springs, gears, ratchets, and linkages, ticking down up to six minutes. Assemble these models one by one from over 130 pieces and learn about how spring - powered devices like wind - up toys and mechanical clocks work. Explore the physics of potential and kinetic energy through hands - on experiments. The snap - together assembly is easy and requires no glue. The kit comes with step - by - step illustrated instructions. Key features: 3 - in - 1 engineering kit to build three self - powered models. Understand potential and kinetic energy and how gears and springs work in various mechanical devices. The race car can drive up to 45 feet. The robot can walk up to 20 inches on two legs. The timer can count down from up to 6 minutes. No batteries or electricity needed. Suitable for ages 6 - 14+. It has 3 experiments, 133 pieces, 64 - page manual, and product dimensions of 10 x 11 x 2.5 inches.
Using the SpringBots kit is a breeze. First, go through the step - by - step illustrated instructions in the kit. Then, start assembling the models one by one from the 133 pieces. Just snap the parts together, no glue required. For the robot, once assembled, wind up the mainspring by hand. Place it on a flat surface and watch it walk on its two legs. For the race car, wind the mainspring and let it zoom across the floor. With the countdown timer, wind it up and set it to start counting down for up to six minutes. When handling the kit, be careful not to lose any of the small pieces. If a part gets stuck during assembly, gently wiggle it to get it in place. After use, store the kit in a dry place to prevent the springs from rusting. If the models seem to slow down over time, you can wind the mainspring a bit more tightly to give them a boost.
