My Idea :My Idea My Idea was that I get a box, get a straw and make a hole in the box so the straw fits in, then I blow a balloon, and tie it on to the tip of the straw.
As soon as I finish, I squeeze the balloon so that the air makes the box move.
Then you don’t have to waste petrol, unless someone squeezes the balloon.
