Balloon Powered Car? - fast balloon powered car

In my science class we have this prodject where we have to make a balloon powered car. The ball must be at a straw that sent the air, so it happens to be connected ...

How I can go very fast or long distance?

How do I get the car?
What should I use for wheels?
What should I use as a straw?
Thank you!
