I smell bullshit
a) Schools are supplied with 35% HCl, not fully conc.

b) If HCl had evaporated, you wouldn't have people alive and breathing in the same room, would you doofus? I spilled 1cc of 50% bromine a couple of years ago and that damn nearly killed me.

Bullshit? Really?
No. I was told a story with roughly these details by my old physics teacher in 1992. There are tweaks for dramatic effect, but all the details are his.

HE may have been lying, sure, but bearing in mind this is framed as a story that I have been told, not something I have directly seen and done, I dare say most intelligent people could figure that possibility out for themselves.

In reply to a) + b), I wouldn't know as I neither work in a school, nor was I there, and nor do I claim either. Doofus.

You don't need to work in a school
To understand that breathing in concentrated acid is not a great idea.

Anyway, I never said it was your bullshit. Could quite easily have been the prof's.

Who cares?
Funny story, well told.

Find me a QOTW answer that is 100% true and I'll find you a b3tan who isn't a closet troll...

to understand that any anecdote will contain at lease some poetic licence.
