What is a mousetrap powered car and how does it work? A mousetrap-powered racer is a vehicle that is powered by the energy of a wound up mousetrap's string.
The most basic design is a follows One end of a string is tied to the tip of a lever arm that is attached to the mousetrap's "snapper arm".
The other end of the string has a loop that is designed to catch a hook attached to a drive axle.
Once the loop is placed over the axle hook, the string is wound around the drive axle by turning the wheels in the oposite direction to the vehicle's intended motion.
As the string is wound around the axle, the snapper's lever arm is pulled closer to the drive axle causing the mousetrap's spring to wind up & store energy.
When the drive wheels are released, the string is pulled off the drive axle by the mousetrap causing the wheels to rotate.
