Mousetrap powered toy cars are great projects for kids. They teach basic physics principles and inspire creativity. The simple design of a mousetrap, powered by a simple helical torsion spring, can be adapted and enhanced with gears and levers to power all sorts of toy vehicles that are simple to build: cars, boats, helicopters, and even airplanes. Even a simple machine dating back to ancient Greece — an Archimedes screw –can utilize a mousetrap to do work. Our project will include a demonstration of the various designs and functionality of mousetrap vehicles and machines. Fun for all ages!
