Ah, good. Sorry for snapping at you. Just don’t say “your phrase is meaningless” to me often
Canned “air” is fun to play with, and I recommend it highly. It’s not so cold to be really dangerous, and it’s easier to get than liquid nitrogen. You can condense it on dry ice. I even spelled it without having to look it up. Here’s the MSDS for anyone concerned.
Remeber, kiddos, use the same precautions while inhaling tetrafluorethane as you would helium or nitrous oxide. There’s no oxygen, so you can’t live on it. Make sure you get plenty of real air between uses.
And don’t inhale directly from the can, since frostbite in your mouth or lungs would suck. Fill a baloon, and let it come to room temperature first.
And don’t do this either. Tetrafluoroethane and its relatives act on the brain in a manner similar to many anaesthetics. It would be all too easy to kill youself this way.
Really? Why isn’t that mentioned in the MSDS? Most of them don’t show rat LD-50 untill where it has displaced too much oxygen, rather than biochemical causes.
So this stuff can kill insects? All I have to do is invert the can?
Definantly going to try this tonight to kill a few fruit flys bugging the hell out of me. Time to die you bastards!!!
Wouldn’t this be considered a very safe method of killing bugs? I mean, can injestion of this spray (on eating surfaces) stay present very long in room temp? Wouldn’t it all just evaporate?
badmana, it does evaporate very quickly. The only way it kills insects is by freezing them when you spray it on them directly out of the can.
Although under some conditions the gas and even the freezing liquid can be flammable. And when it burns, it seems to produce some pretty nasty fumes that burn the eyes and throat and whatnot. So maybe if they’re really toxic, the fumes might kill bugs too! I think I smell a science project in the making.
Having um…experimented with this stuff once or twice in my younger days, I can attest that the effects manifest themselves much too fast to be merely a product of anoxia. Or perhpas a different chemical was used back then. We’re going back nearly 20 years.
Oh ah. You should have said that in the first place.
I never noticed any problems, but then I wasn’t inhaling it in concentrated form. I usually just discharge a full can in a small room in the course of an evening’s experiments… The smell is quite accurately described as ‘ethereal’, by the way.
