Default The BIG CO2 cartridge


This image is 1:1 scale (my monitor resolution is at 1280X1024)


I got it out of an old life jacket (the date on the cartridge said 1976!).

Does anyone know if these are still avalible?

Nice Ratty but i have also found a new thing to use for my Crator makers there called Air Chambers and are sold at pluming stores they are a small section of copper pipe that tapers down to a point at one end adn the other end tapers down to a small bottle necked opening depending on what size u buy they get pretty big the largest i have seen are 6" long and 3/4" in diameter and the bottle necked opening it 3/8 of an inch. Also sence ther copper they have a lower pressure burst rate so they will explode even of u use a slower burning podwers also there pretty cheap the 6" ones are $.50 cents apeace US dollors mind u.

Well ok i'm done i need to get some sleep talk to ya later

How heavy is it? I've got one here that is 268g gross, 60g net. I expect it to make quite a big fucking bang.

That should be interesting. What's the wall thickness on that thing? If it's the same as a regular CO2 cartridge you'll get less bang for your buck as you thought you would, I think. Even still, you can fit at least twice the powder in the large one, and twice the powder means twice the expanding gas...

I'd be interested to see what you blow up with this thing.

I feel a little afraid of using it, because I know it will probably be REALLY powerful and lots of shrapnel.

Find a good rock to cower behind and you'll be fine.

If you aren't going to use it, I'll take it off your hands...
