This is my mousetrap car. It took a while to make. My car would barely move when I first tried to make it get to  7 meters. I moved the smaller, front wheels so that they would touch the ground instead of them being on the top of the car. This helped and my car went about 5 meters, but then would run into the wall. I thought it was very frustrating when my car would not work the way I wanted it to. Building my mousetrap car was a long and frustrating job, but I finished it!
