I'm building a cart which must be powered by TWO elastic bands only,
it must ran at least 2 meters, which isn't hard, but my goal is at
least 12 meters, which isn't very hard either(the longer the better).
I have some ideas of how to power the cart and please help me to
choose and give me some more ideas!
(it must be in 3/4 wheels)
