Mousetrap Car!

My Mousetrap Car

For my project, I built a car that was very similarly structured to this one.

        This car has wheels made from LP records, a crossbar made of wood (some of this design are made with metal but I did not want the car to seem parent-made like others), and a string of fishing line. My mousetrap car was pretty successful when I tested it. It went about 26 feet the last time I tested it. 

        I chose this design because it starts off with a burst of energy as the string unravels and then just as it seems like it is about to stop........IT DOES NOT!! In fact, because of its very large wheels, the car keeps freewheeling and freewheeling and freewheeling....and freewheeling...and freewheeling.....and freewheeling..... Sorry. Point is, that this car has big wheels and uses this because it is hard to stop them from rolling as opposed to small wheels. So that is pretty much my design and why I chose it.
