Racer is part mousetrap part car. It zooms along powered by a mousetrap spring. Learn how potential energy is stored and released as kinetic energy. Zoom over 15 meters that’s 50 feet- with the simple mechanics of spring and string! No need to worry about batteries. The young engineer and scientist will soon discover how powerful a coiled spring can be in providing simple elastic, or stored energy. Replace the four wheels with old CD’s to see if you can go further or faster.
What happens if the spring is twisted? How does a spring store energy? What do a mousetrap, clothespin, and watch all have in common?
Transform the power of a mousetrap into energy. When the mousetrap is released, it will set this cool racer into motion. All parts and detailed instructions are included in building this fun DIY kit.
