In high school shop class, I had a lawnmower gas tank I wanted to
solder.

I washed the tank with host soapy water and let water run through it for
about ten minutes. I then waited for it to dry.

As soon as I hit it with the torch, kaboom and there went part of my
left eyebrow.


I thought when welding fuel tanks you leave them full of water when you
do the welding.
