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.

1.325

1.337(added weight by painting it)

1.338

What's the conversion in mph?

i made one of these in my Tech Ed. (technology education) class, and mine traveled along a 60ft track from beginning to end in 1.651 seconds, and mine was MUCH more aerodynamic then these! but i have to admit, these do look pretty cool.

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.

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!!

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.

I made a car in school and mine went 83 miles per hour it weighed 32 grams :P

[blueberriesrock25]

thats a good idea. i might have to try that.

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

i am buoilding a co2 car for technology class, mine is a 57 bel air funny car, but i am a mopar fan

[creator189]

mine is so much better and i think i set the record 0.453, when it poped the co2 all u saw was the time on the end of the track on the little board thing 30ft track and it only weighed 23g

[SnoProF5135]

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

[shadow49100]

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

[SaturnVII]

Mine went 60 feet in about 1.2 seconds. It was a really basic design.

[rredzone]

thats fast, my best times was .954

my car is the the one and only General Lee 01 c02 car
