BALLOON CAR:

I am in a group with Lyndsey and Emilee:

Our balloon car is basically three CDs for wheels and they are outlined with glue so that the wheels have traction. Also, its balloon has a box with a bottle cap with an opening at the top to keep the air flow constant. The ballon in a normal SDS balloon. The body has two sticks connecting on either side of the CD and then going back to between the other two CDs. The mass is 60 grams and the I do not know the acceleration or speed because we haven't recorded them yet.
