DOC FIZZIX Little Moe Mousetrap Car Kit

Q: How big is the mousetrap itself?

It is as big as a regular mousetrap you would buy at a store. About 5in long and 2-3in wide. (Not really exact measurement, just an estimation.)

Q: We got the kit. What are the washers for? It doesn't keep the car in the middle of the axles.

The washers reduce the friction when the rubber spacers bump into the wood frame so the car travels further and factor. The rubber has a lot of friction on the wood but the metal washes has less friction. It is ok for the axle to move back and forth between the frame (side play). This side play prevents the washers from bumping into the frame and again, lets the car roll further and faster. You can always tighten the the axle up on the frame a little bit but not too much, side play is a good thing.
