We first started building our balloon car in class on the Tuesday, November 29, 2011. We started out with one idea for our car and we continued with that. The first car's materials contained 4 CD's, paper cups, hot glue, cardboard, and 2 paper towel rolls. The CD's served as the wheels for the car and with hot glue the paper towel rolls were glued onto them. There were 2 paper cubs glued together and placed in the middle of each paper towel roll. Glued onto the paper cups was a piece of cardboard which served as the base to the car.
We then discovered that the car only travels one foot so we threw our first design out and started to build a new one the Friday, December 4, 2011. This design is quite successful compared to the first one. The materials in this car contain wooden skewers, straws, Cd's, Styrofoam, and cardboard. The design process is the wooded skewers in straws so that the skewers would be the wheels and the straws would make the wheels spin. Styrofoam and cardboard were glued to each wheel to insure that the wheel would spin properly without the skewer falling out. The straws were glued to the cardboard so the wheels can spin. The balloon is placed on tip used scotch tape, and once the balloon car is ready to be released the balloon is opened and the car begins. We didn't make any expenses for our balloon car because we had all of the materials in our houses. Mr. Kozsan, Kaitlyn's dad helped us design the second car.
