Hi BLT
Great photo and I'd rather not be beside a cylinder having a brain aneurysm like that. Go hydro and dive safe.

Wow that's cool. I like the way it seems to be hovering. Someone shot it, eh? I mean, it didn't just blow, sitting out there in the woods with a guy holding a camera nearby...   |

That looks like a 150 psi aluminum dry powder extinguisher. Didn't take much of a shot to penetrate it.

If you Google “Can a scuba tank really explode if is shot by a rifle?” you will find many people have tried shooting at one. The one I like the best is the guy that wrote in some message board that his experience was that the bullet exit hole is bigger than the entry hole. That in essence created a larger jet nozzle propelling the tank back into the shooter’s general direction. In that particular case it missed the shooter by a small distance. It could have been a good candidate for a Darwin award. |

I saw the guys on "Mythbusters" shooting at a SCUBA cylinder to see if the scene in the movie "Jaws" could really happen. They fired at it end-on and straight through the side and concluded it was a myth since the cylinder failed to explode. I felt like writing the dummies to tell them they forgot to fire a glancing shot at it. I'll bet if the bullet were to put a nice furrow into the side of a full SCUBA cylinder it couldn't help but open right up.

Great picture, obviously a forced failure.
Remember a few year ago when there was a rash of Luxfer failures? Really failures occur at the neck. That is the high stress location. Valves blow off, threads fail, etc.
Fortunately, most failures occur due to excessive plastic deformation, i.e., not passing hydro.
Hydro is keeping the ratio of elastic to plastic deformation in check.
Great pic, keep them coming.
