Kobey- Balloon Car

Balloon car

Last week we had to make balloon cars for our STEAM project. The materials that my group used were cardboard cups, straws, balloons and rubber bands. 

Our balloon car had to do these 4 things:

1. The car  must be propelled forward by the air escaping the balloon.
2. The car must be sturdy and not fall apart when in use.
3. The car must travel at least 5 feet. 
4. The car must travel in approximately a straight line.

Some challenges that my group faced were trying to not pop the balloon,  making holes in the bottle tips,  our car not moving 5 feet and the wheels were not turning. My group didn't complete the challenge because it didn't move 5 feet. We were the only group to have our car move at least half a foot.
