I remember that stuff well - and being deaf in left ear for ten minutes and in my right for 5 hours!
It worked well painted onto the underside of plastic chairs (once dry, exploding when someone sat down and flexed them) or supposedly in one case, painted along the tops of the radiators in the biology lab (until the teacher shouted too loudly).

The watered down school lab stuff seemed to do it just fine...
Thing with hydrogen sulphide is that although it's toxic, it's far stinkier, so you run away because of the smell before it's too bad.
Carbon tet + bleach sounds unlikely. (googles). Acetone + bleach sounds rather more likely.
This was ~45 ya, so CFC.
Reading all the posts in this thread is it any wonder that Britons have won so many Nobel Prizes?
Except at high concentrations when it overwhelms your olfactory receptors (or stuns them) and you cease smelling it. So if you can't smell it, levels have either fallen or risen to a lethal level. ;-)

I see your Collins Gem and raise the OED:
People use it to mean injure, so it has come to mean injure.
You can still buy concentrated ammonia in some hardware stores. I have a feeling Robert Dyas still sell it. For the iodine crystals, you'd have to obtain them from tincture of iodine and allow the alcohol to evaporate.
Not sure - maybe it's more surprising that more of them haven't won Darwins, actually...
Well, being careless and stupid can really further the learning experience. It's only when you're careless, stupid and unlucky that the problems really occur ;)

And I suppose that by definition it's only the guys who haven't had such 'problems' are still around to post their war-stories here!

Thing with hydrogen sulphide is that it kills nerves, so a high enough concentration of it and you can't smell it (or anything else).

Ohh, forgot about that, back in the day when fireworks were actually close to being worth the money they used to 'leak' in the boxes. Collecting all the leaked contents from whatever bonfire party I was taken to became a bit of an obsession.
Not done that myself, I'd say I'd lead a sheltered life but I know otherwise..
Yep. An aerosol full of black paint and a .22 pellet. It took a week to wash the paint off my face.

Have you seen this news report about Tasers?

Mr Benn wibbled:
Could have been worse - expanding foam?

Nah. Yellow paint can (for my Mums old N reg Mini) and I gave my Dad the air rifle and told him that even an old git could not miss from that range. He took the bait.
Ouch. One work suit ruined.

Our Airsporter was effective on such a can at 25 yards - the contents of the can weren't.
