Attempt II

Our second attempt was based on the theory that the air from the balloon would turn the wheels and move the car.

We tried blowing the air on the wheel alone but that didn't work, so we tried adding Styrofoam paddle wheel inserts. That design also didn't work.

We realize that this design did not fulfill the needed requirements to succeed as a car because there was too much friction acting on the wheels which prohibited the movement of the vehicle.
