Pulley power system for record setting distances
The secret to Doc Fizzix's world record setting mousetrap distance traveler is it's unique pulley system that is designed to maximize the transfer of potential energy into linear displacement over a 400% greater pulling distance when compared to conventional propulsion systems. The pulley set-up is designed to maintain a more constant and uniform pulling resulting in an increase in a vehicles efficiency. The High-Tech Pulley Set uses a standard sized cassette tape ribbon as the drive chain instead of the more traditional string because the cassette tape ribbon winds more uniformly and produces more accurate results. All parts are machine made for a perfect fit.
