make something with big , light and thin wheels. That way it will keep rolling after the balloon gives up.

I did this same project last year. I got a 98%. Do what i did

You need:
A Piece of styrofoam
thin wooden dowels
small plastic practice golf balls (wiffle balls)
The casing/shell of a highlighter or marker
your balloon
electrical or hockey tape
hot glue gun

Take your Styrofoam board and glue the 2 dowels to the bottom, spaced evenly apart. then take the wiffle balls and put them on the ends of the dowels, so you have 4 wheels. glue the end of all the dowels so the ball wont come off.

take the balloon and put it over the wider end of the highlighter/marker and tape it. then attatch it somehow to your styrofoam. the key here is that with the air from the balloon coming in from the wider end and going out the narrower end, creates pressure, thus, more thrust. this will make your car go farther and faster.

good luck
