I'm with you guys...

We made gunpowder and the like in chemistry class. Once I and a friend managed to fill the whole classroom with smoke from a petrol-soap mixture. (Cool high flames, too.) In physics the teacher connected one of the girls to a high-voltage source so that her hair stood out like on film... I hope they haven't changed anything!

I no longer have all the recipies for drugs and explosives that were passed among us pupils. I'm sure those politically correct people would object to people learning how to make everything from LSD to RDX... (I suspect the school would have, had they known.)
