When I was 22 I had a cracked brass float with gas in it. I decided I could solder the crack if I could get the gasoline out of the float. Holding it up squeezing took too long. Aha! I'll take it out in the driveway and set it on fire. That bugger heated up and threw a 20 foot flame in the air for about 3-4 minutes. Holy crap, what did I do! Fortunately, I did not burn anything down! That was 67 years ago.
