"I do note that if you run the structure [O2F2 or FOOF] through SciFinder, it comes out with a most unexpected icon that indicates a commercial supplier. That would be the Hangzhou Sage Chemical Company.
"They offer it in 100g, 500g, and 1 kilo amounts, which is interesting, because I don't think a kilo of dioxygen difluoride has ever existed. Someone should call them on this - ask for the free shipping, and if they object, tell them Amazon offers it on this item. Serves 'em right. Morons."

#4Two stories about stuff like this:
1)
A plumber in the town of Hilversum near Utrecht here once had an oxy-acetylene rig like this one http://static.werktuigen.nl/afbeeldingen/advertentie/8577/1/... in the back of his trailer, hit a pretty heavy bump in the road, the whole assembly fell out the back of the trailer.
Because of the force of the impact the reduction valve broke off from one of the cylinders and the whole thing went rocketing up and into the roof of a church a few hundred meters away.
2)
A company that I free-lanced for had inherited an extravagant espresso machine from a bar that went out of business in Amsterdam. The thing was ancient and had been repaired many times, and not exactly by experts.
Over Christmas 1985 it remained plugged in and when we returned to the office on the 26th bits and pieces of the pressure tank were found embedded in the plaster walls.
We were very lucky, if someone had been operating the thing when it blew it would have been a 'closed casket' burial for sure.

#5These stories are always turning up. If this isn't an excellent argument for requiring physics be taught in high school I don't know what is.

I love that particular subset of his blog. My favorite is still the entry on chlorine triflouride ( http://pipeline.corante.com/archives/2008/02/26/sand_wont_sa... ) This stuff is so nasty, it'll burn stuff that's already burnt. Oh, and there's no real way to put it out, so you just have to wait for it to finish eating through whatever was unfortunate enough to be in the vicinity when the spill happened.

#7Dave Arnold at www.cookingissues.com posted about this recently. Their protocol for transferring the dewars includes letting the tank take the elevator alone. One particular time a student had set the dewar down a little hard, and the pressure had caused the tank to vent a minute later in the elevator, and blow a hole in the ceiling of the elevator. Had anyone ridden with it, they likely would have asphyxiated

#8I feel a lot better about the big liquid nitrogen tank I had to sit next to while at a internship last summer. That thing was hissing all the time.

That URL needs to lose a trailing hyphen:
