Dumb things that you did.......because you didn't know any better.
around 18.....put a can of header spray paint on my moms gas stove in a pot of water (you know to heat it up so it would spray better)...went back outside to sand on my headers some more, heard a boom........the kitchen was white and the stove top looked like a launch pad, there was a hole in the kitchen ceiling where the paint can went through......
