🛞 Upgrade your STEM ride: smoother, faster, smarter!
This 20-pack of flexible rubber CD/DVD wheel spacers converts standard CD/DVD holes to fit 3/16" axles, acting as shock absorbers to reduce vibrations and improve speed and distance for mousetrap cars, rubber band racers, and other STEM science projects. Made in the USA by Doc Fizzix, these lightweight spacers are a must-have for any serious young engineer.

For building mouse trap cars
These are very helpful for building mouse trap cars. They go inside the CDs and you can then put a wooden skewer through it. The kids think they smelled good!
