They don't like seeing the recipies contained in them ... now many people on
rec.pyrotechnics used to make PE4, Naplam, Nitro, TNT etc.

I remember a chemistry practical at school where we made NT;
probably ended up with a mixture of mono- and di-nitrotoluene.
(Can't recall if it was O-level or A-level.)
Had to keep the test tube running under a tap to keep it cool.
At the end of the lesson, someone's blew up when they poured it
down the sink. Teacher thought it was probably triggered by some
other chemical residue in the sink. Blew out a ceiling tile, but
no other harm done.

I bet they don't do that in GCSE or A-level chemistry any more.
