Ferric Chloride fatality...

Yes, 200ml of the solution, about half the size my usual cup of coffee, only 11.5g of actual Ferric Chloride - 
that's probably only a couple of balls of it in the solid state - and they look a bit like sweets.  People 
with children take note!

When I was about 14 or 15 I was etching a board in the kitchen (my mother was out :-) and on lifting one end 
out of the tray to see if it was done, it slipped and dropped back, and a splashed drop hit me straight in the 
eye.  I spun round in a bit of a panic as things started to feel a bit warm, then I told my self to calm down 
and deal with it - made my way to the sink with one eye open, turned the cold tap on full, got a glass and 
repeatedly filled it and threw it into my eye, opening the latter after a couple of goes to make sure it all 
got washed out.  Did this for about five minutes.  No ill effects that I'm aware of!  (Very lucky, I know, but 
that was in the days before things like safety goggles were even heard of, let alone available to schoolboys).
