The Doc Fizzix propulsion system was designed to work with all mousetrap and rubber band powered vehicle projects and it the most efficient propulsion system available. This bulk pack gives you 100 axle hooks for all your mousetrap and/or rubber band STEM vehicle projects, order as many sets as you need for your next large group activity.

A mousetrap racer is a vehicle that is powered by the energy of a wound up mousetrap’s spring. The most basic propulsion system is to tie one end of a string 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 opposite direction to the vehicle intended motion. As the string is wound around the axle by the turning of the wheels, the snapper’s lever arm is pulled closer to the drive axle causing the mousetrap’s spring to “wind-up” and store energy. When the drive wheels are released, the string is pulled off the drive axle by the mousetrap causing the wheels to rotate.
