So in the [thread=505137]Swiss Army Knife thread,[/thread] it came up that I’d once set myself afire.
I was an oceanography graduate student at the time. I’d been to the antarctic and collected a bunch of water samples for dissolved sulfur compounds, and had to analyse them back in the US of A. I had arranged to work with an old flame ionization detector gas chromatograph, which lived in an underutilized outbuilding. I’d put the seawater sample in a gastight chamber and submerge it in boiling water, which would drive out all the interesting chemicals. The chemical gases would go down a tube filled with resins, which was submerged in liquid nitrogen *, where they would stick, getting concentrated. I would then switch the liquid nitrogen with boiling oil, driving the concentrated gases into the gas chromatograph, where they would hit a pilot light, which would ignite them. The machine would then detect the amount of gas by detecting the burny-ness of the flame.
This was a very boring process. Water in, sit, boil, sit, liquid nitrogen off, boiling oil on, sit, beep, push button, repeat. The flame kept going out, and the machine would complain, and I had to quick relight the flame with my trusty zippo, or else the sample would be lost. After a week of this, all alone in the world, isolated in an outbuilding, I’m living like a bachelor. I’m reading cheezy mystery novels and wearing my tatty-est, holey-est jeans, and old tee shirts - water in, sit, boil, sit, liquid nitrogen off, boiling oil on, sit, beep, push button, repeat. I discover that I can light the zippo off the jeans of my thigh by rolling the wheel along my leg, then flick the lid down on the zippo to put it out.
After another week of this, I’m sitting there, :water in, sit, read, play with lighter, boil, sit, read, play with lighter, liquid nitrogen off, boiling oil on, sit read, play with lighter, beep, push button, repeat.
Happy in my carefree isolation, I fart. The gas shoots out my butt in the usual fashion, but finds an exit to the outside world through the holes in my jeans. The leading edge of noxious gas meets the Zippo flame and ignites - I see a tongue of blue flame shoot into my pants - did I mention drawers were not coming to work anymore? - and feel my pubic hairs burst into flame.
I yell, leap up, drop trou and, ahem, beat out my testicles. I redress and run to the washroom, so I can inspect the damage. It’s pretty deforested, but I’m otherwise fine.
Moral of the story? Science is a dangerous calling, just like on the late late show.
Now that I’ve set the bar nice and low, tell me your embarrassing story.
*I also froze my tongue to a banana during this period. Go figure.
