Oh, boy, does aluminum have a high rate of replacement!!!

I discovered this by making the mistake of trying to etch a circuit
board in an aluminum pan. Bad Mistake (the caps are not accidental).
This reaction goes fast enough to boil the FeCl - not to mention eating 
completely through the pan and spilling nasty etchant all over.

I was young, then...
