Input: Text: this happened around 9 hours ago, and i still have that post-concert-mildy-concerning ring in my ears.

to preface, i work for a small health-sciences company, which occasionally obtains interesting (usually unstudied) new tech. the relevant technology to this story is a gas generation device that creates a water-derived gas that the inventor has yet to identify. it's some state of gaseous hydrogen and oxygen with strange chemical properties (strange to me, at least, but i'm not great with chemistry). it has some biomedical uses, apparently, but i'm​ more fascinated by it's behavior when ignited. run it through a welding torch, and it burns with an intense, bright purple, weirdly narrow flame, which ultimately condenses back to liquid water. it seems to be mostly self-reacting, imploding from a gas to a liquid directly. anyway, the important point is that it implodes upon ignition.

this machine has been sitting unused for a while. having a reputation as a capable tinkerer, i was tasked with checking it's functionality. i got it set up, powered it on, and connected a tiny jeweler's torch to the outline. unfortunately, the rate at which the gas is produced is much faster than the rate that it can escape the torch head. the gas runs through a big plexiglass tube partially filled with water, for various reasons, and my temporary solution for the build-up of pressure was to leave the lid of this tube somewhat loose. not ideal, but i was just testing it briefly. 

at this point, i spark the torch and get a beautiful little flame. testing successful! i waited for a minute to make sure it was stable, and then shut the valve on the torch head really quickly. i had determined in the past that this was an effective shut-off procedure, and it seemed to work safely. there was the usual pop as the gas in the nozzle finished reacting, and then nothing. at this point, i was confident that the risk of implosive flashback was in the past. the rest can be seen in the gif. after a delay of a few seconds, there was a louder pop, and a bright flash in the clear section of the line. i think, "close call — i'm not sure how that happened, but at least it didn't reach the plexiglass chamber." i start to consider detaching the torch line, and then i'm suddenly turned away from the machine with a scary combination of nothing and everything ringing in my ears.

according to my coworkers, it sounded like a shotgun. the lid of the tube shot off, and the cylindrical walls snapped clean off of the base. by a cruel coincidence​, the weekly company meeting was underway in the adjacent room, so i had plenty of alarmed superiors to explain myself to :-p. that went well, to my relief.

this is the interesting part of the security camera footage. you'll have to watch closely to see the first flashback, and the second one isn't really visible. [imgur](http://imgur.com/a/b0cny)

i know how carelessly stupid i was, but feel free to reiterate the point in the comments ;)

i plan to be a tad more careful with this stuff in the future. i like my ability to hear things.
