Before even creating Philip, we both agreed that our balloon car had to be light weight and have little friction interfering with the wheels (And even before this, we decided to name our car Philip).We decided to use:
- 4 CDs
- 4 markers
- plastic pipe (cut into ¼ inch pieces)
- Bertucci's take-out box
- tissue box
- balloon
- lots of tape
The idea was to use the markers as axles, but we soon realized that they were pretty heavy. So we removed the ink and the tips of the markers to make them lighter. The marker-axles were glued to the bottom of the Bertucci's box. Then, the CDs were placed on the axles with a ring of plastic pipe glued on either side to hold the wheels in place. We noticed that if we attatched our balloon to the car now, it would interfere with the spinning of the wheels. Carelessly, we grabbed a tissue box and glued it onto our car to raise the balloon above the wheels. Then we blew up our balloon, attatched it, and watched.
Fail. :P We're pretty sure that the tissue box was too heavy. It also wasn't very aerodynamic. We're going to need lighter materials if we want this car to go anywhere. It's back to the drawing board.
