This is the worlds fastest mousetrap powered car designed after Doc Fizzix's own record-setting racer that traveled 5 meters in less than 1.2 seconds. The Speed-Trap Racer is engineered to generate a tremendous amount of torque while maximizing the transfer of potential energy into the kinetic energy over a 5 meter distance.  The Speed-Trap Racer is the clear winner for all speed contest and “king of the hill” climbing challenges.

The worlds fastest mousetrap dragster
By far, the biggest secret to this mousetrap powered car's success is the design of its ultra sticky foam wheels that are essential for keeping the Speed-Trap Racer from spinning out at the start line and providing maximum traction to the road. Plans include tips on how you can adjust the gearing of the racer so that you can "dial in" the power delivery to match traction conditions.

Includes the following: balsa wood, ultra sticky foam wheels, low Inertia wheels, brass axle tubing, brass lever arm, Victor mouse trap, thrust bearings, axle hook, step-by-step plans, kevlar string, and secret performance tips.
