True Story: My first experience in making PCB's didn't go so well. I was in junior high and just started getting into electronics because I was obsessed with the dream of creating my own car-audio amps (think Kicker, JBL, etc). Note I was way to young for even a driver's license but that didn't stop me from planning out for when I was old enough to roll (aka Weird Al - White & Nerdy) Anyway, I created my first PCB in autocad and took it out into the garage for etching... "Hmmm I needed something to pour the etching acid into... Something that I could throw away when I'm done... Ah! This pie tin will work out nicely!" So I took the pie tin and placed it on the surface of my Dad's table saw and then placed my unetched PCB in the tin. Then next step of course was to pour the acid in the tin...... $%^&!!!!! The acid reacted violently with the metal of the tin and within seconds the bottom of the tin was completed digested by the acid which then proceeded to flow out of the tin, onto the table saw, and then all over the garage floor. To this day, the table saw still has a rusty look to it and there is a nice brown stain in the concrete. My career as a "EE" was founded on pure genius!
