physcics project. rubber band car ideas

[v8power]

so for one of my physics class we have to make a rubber band car, using paper and coat hanger wire. now i know how to get it to go all that great stuff, but i want to make a one wheeled car then i am guaranteed a much needed A. the wheel can be wide, hollow anything. what you got?

Well, the wheel itself would have to be much lighter than the mechanism powering it. That way all the energy is not used to spin the mechanism backwards instead of moving the wheel. Since there is no limitation on the wheel's size, maybe a empty toilet paper roll could be used? Either that, or a wheel in which a leg would drag behind on each side of the wheel to keep it stabilized.

i figured it out. i had one wheel and one axle. then left two pieces of coat hanger drag behind it for stability....
