The material we used was rubbernands, cardboard, popstickle sticks and duck tape.
First we got a square in the cardboard and then put the axial in, the we rolled up tapped to the axial and put the cd's and we put the rubber band on.
Our first car went 12 feet
Then we added more tape to the band so we could wind it more because it kept falling off
Our second try went 15 feet because we winded it up a lot more
The on our third try we winded it up more then
We winded our car up to much and the car folded, we had to restart
We did our same design and our car isn't going as far as it used to, so we our brainstorming new ideas and trying to break our record
We keep only getting fifteen and less feet and we keep trying to beat our record
We tried a new technique and we got 17 feet aging so our new technique is doing better
