For a fun classroom activity that really measures up, check out the Toolbox Racer Kit.
Powered by the toolbox’s favorite occupant – the tape measure – this racer is quick and simple to build. It demonstrates the elastic potential energy of the tape measure’s spring and gets students excited about learning! Students can change out the 6' tape measure with a bigger one.
The racing setup is simple – just tape and string. Requires a tape measure – our 6' economy tape measure is recommended – duct tape, twine, and white glue, all sold separately.
