MOUSETRAP POWERED CARS

CDs and DVDs make great wheels because of their low rotation inertia and great aerodynamics but come with the added challenge of attaching to an axle. Doc Fizzix manufactures a special, flexible rubber insert that is designed to fit perfectly inside any standard sized CD/DVD so it can then be fitted to a 3/16" inch diameter axle. Even the smoothest of hallways and surfaces have some small imperfections and bumps that can steal energy from a moving vehicle causing a decrease in performance. Our CD/DVD inserts are made from a flexible rubber that is also engineered to act as a shock absorber to help damper small bumps and imperfections along a floor's surface while providing for a smoother ride with less wasted energy. Our shock absorbing CD/DVD Inserts will help increase both the speed and the travel distance of your mousetrap and/or rubber band powered STEM vehicle project. Spacers can also be used to center an axle between the frame in order to cut down on the "side-to-side" movement of the axle. This is a hard to find item and is a "must have" part when using CDs and DVDs as wheels with any mousetrap, rubber, balloon, and/or STEM vehicle project. Give your next project the winning edge and use our shock absorber CD/DVD Wheel Inserts. You get 20 flexible CD/DVD rubber spacers that fit perfectly inside any standard sized CD/DVD opening to converts the hole size down to fit a 3/16" inch diameter axle.
