Yesterday Deanne decided to sort a toy storage area that we have, and she pulled out this mousetrap-powered car that Alison and I built years ago. I had forgotten all about it, so it was pretty exciting to see. It needed some minor repairs, but it still works!


Its powered by two mouse traps which lift a wire that pulls a string that is wrapped around the rear axle. The wheels are made from two plastic Pepsi bottles, which have rubber bands around them for traction.

The axles are made from a wooden dowel, and are attached by a folded over piece of the Pepsi bottle, stapled to the bottom of the thin board that gives it its frame.The rear uses two pieces of plastic with a space in the middle where the string comes down to wrap around the axle.

It goes about 10-12 feet!
