This is not spam, but a warning. PVC will fail suddenly after a while. This was band member that hurt badly by a T-Shirt launcher explosion.

ol all my teamates were look at me like what the heck are you doing
How much does the shell weigh? Im trying to build something similar but idk how much a 16g Co2 cartridge can shoot.

about the co2 cartridge: where to get it? is it used for paintball guns? or maybe for a soda machine?
those ones, sometimes are used for paintball guns, but they are more commonly used for bb guns and air rifles. they are also relatively common for CO2 powered airsoft guns. you should be able to find them either online, or the sporting goods section of your local department store, by the airsoft and paintball guns.
my local deparrtment store doesnt have airsoft, i have to go to a weapon store (they sell real weapons, paintball and airsoft). i now use a 300grams CO2 soda-machine-cartridge. ill post an instructable soon
why do soda machines need a co2 cartridge?

....sigh....WALMART and if you're canadian....CANDATIAN TIRE
What about attaching it to the gun? you would need a rail grip. Where can I find a how to on the rail grip?
buy a rail, glue it on, done
or a screw tube (metal band which is tightened around the fixture using a screw

I take the risk of sounding stupid, but could you explain how the grenades themselves work a little more?
temp munkeeboy6 years ago
the co2 cartridge is used to shoot all the airsofts out of the party popper. It's essentialy a small pneumatic potato cannon.
what about attachment? is there a rail attachment to these steps?

how many times do u have to pump to pressurize it?
sgtmik (author)  engineer_017 years ago
u dont have to pump it. IT USES CO2. just open the back valve and colse it. this will pressurize the chamber. ;-)
nice, i hate those overpriced commercial ones.
