Step 1: Screw Eye Screws Into Mousetrap and Attach Base
1. Twist the eye screws into the side of the mousetrap opposite the “bait” hook. They should be as close to the edges as you can get them without splitting the wood.
2. Duct tape the mousetrap down to one end of the paint stirring stick. If the mousetrap arm is held down with a little staple type thing, remove it.

Make Your Own Mousetrap Powered Car
There’s a kinder way to take advantage of the energy stored in a mousetrap’s torsion spring: make a mousetrap-powered car! NYU-Poly PhD candidate Dustyn Roberts created this project, featured in her book, Making Things Move: DIY Mechanisms for Inventors, Hobbyists, and Artists (McGraw-Hill, 2010).
- 1/4” diameter wooden dowel
- 2 eye screws that the dowel fits into (like McMaster #9496T27)
- 24" of monofilament (fishing line)
- 2 laser cut wheels (make yourself, or order from Ponoko.com)
- Wooden paint stirring stick
- Ping-pong ball
- Multi-tool with knife and file
- Duct tape
