so to tell you how to pull a cart across the floor with a rubber band. yeah. so anyway what you do is you stretch a rubber band WAAAAAAY far and you tie it to a wall and a cart. then you let it go and PRESTO the cart flies through the wall! YAY! and that has something to do with elastic force! because the rubber band is like elastic!
