Little Moe MTV

The Little Moe kit from Doc Fizzix is designed for students who have limited access to tools or are new to building mousetrap vehicles, and it requires only glue for construction. Little Moe creates one of the fastest mousetrap cars and travels distances from 15 to 30 meters (49 to 98 feet). Little Moe can be built in less than 30 minutes for most first-time builders. The kit is predrilled and ready to assemble and includes the following materials:

Two Pre-Drilled Balsa Wood Side Rails (8" x 1/2" x 1/4")
Two Brass Tubing Axles (6 x 3/16")
One Brass Tubing Lever Arm (6 x 1/8")
Four DVD Wheels
Eight Rubber DVD/CD Spacers
Four Metal Thrush Washers
One Victor Mousetrap
One Zip Lock Axle Hook
One 36" long piece of Kevlar String
One Top Secret Construction Guide and Performance Tips Sheet

REQUIRES: CA Glue and Needle Nose Pliers
SPECS: Length: 13" (330mm), Width: 6" (152mm)

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 set mousetrap's spring. The most basic design is as 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 opposite 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.
