For physics we have a project to make a car, made out of anything but leggos k'nex. The only way to power the car is from a rubber band.
I already have a few ideas in mind, and I've decided I'm gonna use records for the wheels, but if anyone on here has done this before or likes this kind of stuff, let me know of any designs you have.
