I remember a chem. instuctor in 1st year Sci who overheated some in a
demo lab instuction class and filled the 300 seat lecture room with thick
purple smoke necessitating it's evacuation. It was hilarious.
I've often wondered if he hadn't done it on purpose, as he was an amusing
instructor with a Columbo-like personality.

I wonder if children's chemistry sets still come
with all the
interesting chemicals?
Nope, no potassium perchlorate, potassium nitrate, but plenty of sodium
laurel sulfate.
No iodine crystals, either, I take it?
NB: If you don't know what you could do with these you probably had a much
safer childhood. -- Eric Dittman dittman(a)dittman.net Check out the DEC
