LoL...Lance beat me to the oxygen isn't flammable part. Drat me for being in Egypt. It just adds fuel to the fire. So if you see movies where someone sets an "oxygen" line on fire in a hospital or whatnot, it's sooo fake. It can't hold any flammable stream like say...oh.... propane coming out of a nozzle can.

Of course you could always still create your own missle projectiles with co2 cannisters (the small ones)... I read a story online about this kid and a 20 oz. co2 for his paintball gun became de-valved when he was unscrewing it and it shot out of his hand and crushed the forehead of a mom across the way.

It's why you always point it at the ground when you unscrew it.
