    Dilute it with enough water so the pH is close to neutral (adding the acid to the water not vice versa if it is conc. HCl) or neutralise it with a base to give a salt and water.

    That was my introduction - at grammar school - to hydrochloric (and most of the other) acids. Everyone was given test tubes, each with a different diluted acid, and told to drink them.
    Just to show us that, treated correctly, acid, and chemicals generally, were nothing to be scared of.

    I think that would be frowned upon nowadays...

    BTW did they taste noticeably sour?

    I'd imagine HSE officials would have heart attacks 1.

    It was 45+ years ago! I can't remember.

    1 Those were days. I remember one after-school gym club where we'd discovered that you could take a climbing rope to the top of the wall bars (about 16 feet up), push it away from you to make it swing and then do a "tarzan-leap" to catch it and swing across the gym to the top of the next set of bars.
    All great fun until my brother mistimed his leap and landed face-first on floor.
    The only comment from the teacher was "Would you move your brother elsewhere please? He's bleeding and making a mess of the wooden tiling".

    I very much doubt the H&S would let anyone nowadays give the kids some mercury and let them play with pushing beads of the stuff all over the lab bench as I vividly recall doing --- year 8 or 9 --- so that's more than 50 years ago.

    We did the same 25 years ago, but I think you're right, I'm sure it will be verboten now...
