OH, Did I EVER play with fire. Gasoline was my poison.
My parents have an extra wooded lot next to their house (about 3/4 acre). So, one dry summer day, I got the brilliant idea to carry some gas out into the woods and set fire to it. I figged and nice sandy spot would work nicely.
So, I proceeded to dump said gasoline into the sand, (watching in amazment how quickly it soaked up and spread). I then stuck the match, failing to realize I was now standing on gas soaked sand.
WHOOOF!!!!!!!
I looked down and my shoes were on fire, so, what did I do? RAN out of the woods to the back yard, dropping burning pieces all over the groud (which was covered in dry leaves).
My dad actually saw the flash from the living room window. He saw me go into the woods carrying the coffee can and was wonder what I was up to. Dad managed to put me out and the woods before the whole works went up.
He was not pleased

Course, you'd think old age would make you smart. NOT. So when I was 24 or so, my buddy and I decided to fill a garbage bag full of Acetylene gas from his Dad's torch, which was in his 40x80 enclosed shed. It looked pretty good actually, holding on to 10 gallon bag full of acetylene. We twist tied it shut, intending to shoot a bottle rocket into it once we got outside. We never got the chance.
Anyone ever hear of static electricity???
WHOMP!!!
My buddy had just put it down next to the tractor where is apparently grounded out and blew up. We blew out every window in the shed along with 2 window in the car that was parked in the shed.
His dad was not pleased

My ears rang for about a week....
With all the crap I did, its amazing I survived this long....
