CO2 Car Racing


One of my colleagues asked me to create a dramatic race sequence to heighten student interest in his CO2-propelled car design project. Students race their successful designs on Race Day. I stretch the 3-seconds of action using iMovie, and enhance the audio with iMovie sound effects and GarageBand loops.

    i just finished my tech class i have the second fastest car in 6th grade it went 10 yards with 35-40 mph cartiriges mine went 42 it is really aerodynamic

  2. chris carey says

    i car made it down about a 15 foot track in .5 seconds

  3. Jonathan Hunt says

    i just raced my car! It only got 1.19 secs though

    What's the conversion in mph?

    Everything used for racing came from a Pittsco catelog, out of Pittsburgh, Kansas. (Yeah, Kansas…not a misprint) Looks like the track had lots of bumps; but I agree with you. I probably didn't record the best cars, but the students cut and formed each of them.

    I just made the video for a friend to increase student interest in the CO2 project. As I recall, all cars are made of a lightweight balsa wood chassis, hand-crafted and painted by each student. After two cars are in place, a computer program linked to the track performs a sequence of track checks, pierces both CO2 tanks in unison, and times each heat, compiling a tote board ranking each car running that day.

    man can u tell me the weight of the car, what capacity of co2 tank?, and how the hell you open the co2 tank?
    hope u answer i need help!!

    that's what the students thought when my colleague showed it to his classes
