Beentowns exploding hairspray can came to mind yesterday when I had a turbo torch explode in my hand. I was soldering some copper when I noticed the smell of acetylene. The hose was leaking and sending gas up the sleeve of my shirt. Just as I was reaching to turn it off it ignited sending a fire ball out the end of my sleeve. Got a nice burn on the palm of my hand and side of my thumb. Wasn't funny at the time but looking back I was wishing there was a video camera around. Would have been yourtube gold.
