Good old loony chemistry teacher
Although he was probably only in his late 30's at the time, to a 15yr old, thats almost dead. Anyway... apart from some very sage advice (http://b3ta.com/questions/ignoringinstructions/post54110), he also managed to inspire one hell of a curiosity in anyone who bothered to listen to him.

The most memorable of which was the very first lesson of my last year of secondary school. Cue Mr. M holding two test tubes, both half full of clear liquid. Pour both into a beaker and hey presto! it now looks like someone's mashed a couple of bags of skittles in their food and then put a stool sample in there.

He then says "thats nothing" and proceeds to pour a load of hydrochloric acid into the beaker, upon which, the skittle poo disappears and the liquid returns to being clear again.

"If you want to know how that works - Pick A-Level chemistry for when you leave"

Needless to say I did.

So, Did you find out how it worked?
It's too late for me to pick that subject. I'd blow up the office.
