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.

Problem : Problem We are wasting petrol!
But we don’t waist air!
Step 1 : Step 1 Put the box on your table, than put holes in the parts that the wheels and straw will come in.
Step 2 : Step 2 Add the wheels on the holes, and put the straw on the back part of the box, were the hole was.
Step 3 : Step 3 Blow up the balloon and then stick it onto the straw.
Results : Results My project did not work, so I decided to get a real car, and blow the balloon, and stick it on the car.
Unfortunately I had to give up, none worked.
