Well, my CO2 car that I built for a race for science class came in first place school-wide. It raced down a 102 ft. straight track, guided by a fishing line. My time was 0.62 seconds. The closest other time was 0.88 seconds. I would have pics but the camera battery crapped out. I'll get pics up as soon as possible.
brings back memories of when I was in jr high I was in a model rocketry class, and an assignment we had was to design and build a rocket and everybody but me was more concerned about the looks I was more concerned about performance my design was pretty much just enough body to wrap around an Estes "D" engine with some basic fins and no parachute. I had it painted flat camo...the teacher loved it how it was so basic. When we launched our rockets you didnt see much of mine it was gone in a flash and never seen again...lol
