Doc Fizzix CD/DVD Wheel Spacers (20 Pack) for Mousetrap Cars, Rubber Band Racers, STEM Science Projects

DESCRIPTION:
CDs and DVDs make great wheels but the biggest challenge is attaching them to an axle. Doc Fizzix manufactures a special rubber insert that is designed to fit perfectly inside any CD/DVD so that it can be fit onto a 3/16-inch axle. Spacers are made from a lightweight, flexible, rubber that also acts as a cushion to smooth out a vehicle's performance. Spacers can also be used to center an axle between the frame of a vehicle 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 for making a mousetrap powered racer. CD/DVD spacers comes in a pack of 20 CD/DVD spacers with a complete step-by-step instruction guide.
