Amusing Geeky Link Of The Day..

Recommended Posts

I haven't had such a scientific laugh in a long time. It's all the better for me being an erstwhile chemist remembering why he got out of this stuff in the first place.

I did Chemistry A-level and I tell not a lie but 3 of the teachers had glass eyes. Made me decide I didn't really want to do something chemistry related when I left.

Spent a year working in a chemical /solvents factory when I was younger.. the worst thing we had to handle was Hydrofluoric Acid, the one that suddenly kills you several hours after an apparently minor exposure.

One of the real fun ones is making up 100 liters of 50% sulphuric acid. Given that the 96% stuff and water boil when mixed, which is fine in a test tube but disturbing when it's enough to completely dissolve you.

Funny you should mention those two, my first job as a chemist was in the lab of a specialist waste treatment company, and we had to deal with both of those.

Apparently the problem with HF is that if you get it on your skin it will continue to eat through you even after you think you have neutralised it, so you have to inject the neutraliser deeper than the HF has currently progressed using a hypodermic needle. That is one of the most unpleasant things I can imagine.

And the handling of oleum is one of the few things that ever really scared me in the lab.

Never handled anything madly explosive and nothing more corrosive than conc mineral acids.

I did work with an awful lot of carcinogens and radiation though. Plus I smoke, drink, and eat loads of red meat. I'm so getting cancer. :ph34r:

Oleum, but HF is bad too! :huh:
