Balloon Car Project

The Black Mobile

Our car design is made out of a paper towel holder, two shish kabob sticks, three small straws, two balloons, four milk caps, and duct tape. The way our car works is that to make the wheels move I put the sticks through straws and taped them to the bottom of the car. Then I cut a hole in the milk caps and  put duct tape on the front and back of all the caps and stuck them onto the sticks. To make it go we put one balloon in the other then we put it on a short straw with a rubber band, to make it stay, then we duct taped it on top of the car with the open part of the straw facing the back of the car. Some unique features of our car is that two of the wheels are not the same.
