I am building a knex rollercoaster in the shape of a U. It is 12 feet by 8 feet. I was wondering can I use a small co2 cartrige to send it up the track. I think it will work. do not think I will try it
Will It Work ??????

I think it will work, but too well. It will probably be too powerful and may very well cause the car to break away from the track. I would not reccomend it, if you are going to try it anyway, be careful. Those CO2 cartridges have a surprising amount of pressure built up inside them.

When I was in high school, my friends and I constricted a CO2 morter. It was plastic PVC pipe with a stopper and a nail on the inside of the end pipe. You would drop the CO2 down the pipe, and stay away from the muzzle. It would shoot so far, we sometimes lost sight of the thing. Where did it land? I dunno.
Be careful with CO2 cartridges. Ask a friend of mine when we were testing out CO2 cartridge powered cars, being hit by one of those things ain't fun. I recommend you duct tape that thing down to the K'NEX car, and make sure it doesn't fly off. Especially if you're testing it inside, that thing can do alot of damage.
Soggy: Reminds me of what my friends and I did just a few days ago for their physics video. We built a cannon using PVC pipe, and we launched these stuffed hackey-sack type balls (pretty soft). We launched it a good 50 yards, but that was a hell of a loud shot! :)
Rats, the site seems to be gone, but along similar lines, there was a project called the BFPG-9000, an attempt to make a supersonic potato gun. If memory serves, they got the potato up to an estimated 550mph, but the supersonic attempt failed because the barrel shattered under the load.
This reminds me of when Arrow tried to make the suspended coaster go upside-down. The cars broke free from the chassis and when through a brick wall. The CO2 will overpower the train uphill and remain in contact with the celing for awhile.
