Build a motorized robot, a speedy race car, and a countdown timer without using any batteries or electrical power! The magic lies in the mainspring, a spiral-shaped spring. When you wind it up by hand, it stores energy. As it discharges, this energy turns into motion. The robot's mainspring turns gears, making it walk on two legs. The race car zooms across the floor as its mainspring uncoils and spins the wheels. The countdown timer uses a complex spring and gear system to tick down up to six minutes. Assemble these models from over 130 pieces and learn about spring-powered devices like wind-up toys and mechanical clocks. Explore 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.

Using the SpringBots 3-in-1 set is a breeze. First, find a clean and flat surface to start assembling. Take your time to follow the step-by-step illustrated instructions that come with the kit. You don't need any glue, just snap the over 130 pieces together. For the robot, make sure the gears connected to the mainspring are properly aligned so it can march forward on its two legs. When building the race car, ensure the wheels are attached firmly so it can zoom across the floor smoothly. With the countdown timer, be careful while setting up the complex spring and gear system. To wind up the mainspring, turn the winding key slowly and steadily. When you're done playing, store the set in a dry place away from direct sunlight. If any pieces get dirty, you can gently wipe them with a dry cloth. Don't try to force any pieces together as it might damage them. Enjoy exploring the world of spring-powered devices with your SpringBots!
