Put a Spring in Your STEM

With this Thames & Kosmos STEM kit you can build a motorized robot, a race car and a countdown timer, none of which need batteries or electrical power to run. How does that work, you ask? Via the magic of a spiral-shaped main spring that stores energy when wound by hand. You know—like a clock or a wristwatch, or a cool Steampunk machine. Kids will learn about potential and kinetic energy, how gears and springs function in different mechanical devices, and lots of other stuff. The car drives up to 60 feet, the robot walks 20 inches, and the timer lasts 6 minutes. Includes (133) pieces, and a (64)-page full-color manual with tons of info and details on the (3) experiments/builds. Ages 6+ with help, or 9+ for anyone who wants to go it alone. !WARNING: CHOKING HAZARD–Small Parts. Not for children under 3 yrs.
