Hi, my name is Crystal and this is my Co2 car that I designed in my Technology class at Naches Valley Middle School. It took me about two and a half weeks to make this (thats a long time ). First I had to draw thumbnail pictures, then a full scale one of the actual size and shape. After I got done doing that I cut it out of a piece of wood. Then I had to sand it till it was really smooth. Then I had to wet it down and wait for it to dry and then sand it more. I had to do that about three more times after that. I then put the first coat of paint as the primer and then sanded it so more. I repeated it one more time. Then it was time to put the final coats of paint on. The color I chose was black I had to put about four or five coats of black on my car. When I got ready to race my car I had to set it up by myself. I had a lot of fun doing it. I learned a lot about Co2 car's and what a Co2 is. This as a very fun project but if I were to do it all over again I would hallow it out to make it weigh less and go faster.
