The two balloons were cut into strips, tied together, stretched out and attached to fishing line, attached to a fly-wheel, attached to the driving wheels (back) of the vehicle. The rubber balloon band was twisted and then released to provide power to turn the wheels.
balsa wood frame and wheels
Create some sort of friction on the wheels (possibly by stretching a rubber band around each back wheel). The vehicle would have traveled much further if the wheels had not spun around without traction at the beginning of the run.
It was fun. Thanks for providing the opportunity for all of us to participate....Looking forward to next year.
