Hi, my name is Tara. I am a student at Naches Valley Middle School. In Technology, we made Co2 cars. The way we made them was first we had to make 6 thumbnail drawings. Then we picked our favorite one then drew it so it was the actual size. After that we cut the wood so it looked like our favorite drawing. Then we sanded it until it was smooth. Then we wet it down, let dry, then sanded it again and repeated this process about 4 times. Then after it was done we started painting it. When we got done painting the car I put eyescrews on the bottom of the car. Then I put wheels on it. After I got done with my car it weighed about 30 ounces. That is how I made my Co2 car .
