Mousetrap cars

Students had to construct a car that would travel 5 meters using the energy from the mouse trap spring as the method of propulsion. A mousetrap powered car is a vehicle that uses a mouse trap for a motor. There are many different ideas but the most common and probably the most successful idea is to attach a string to the mouse trap and axle. In this method one end of a string is attached or tied to the arm on the mousetrap and the other end of the string is wound around an axle. By winding the string around the axle the mouse trap's spring is stretched and now you have your stored energy. As the mousetrap car is released the mouse trap pulls the string off of the axle causing the wheels to turn and off the vehicle goes. Using their creativity and ingenuity, the cars were awesome. After trial and error and much tweaking, the project culminated in a mouse trap car race. Everyone was a winner!
