Lets see...lit hand on fire with gas...hand was coverned in vasoline, so it didn't burn. Nothing too bad with that. However, on that same night, decided fire was much too small and dumped some acetone onto it...the flame went up the stream and into the can. My brother and I threw the can, which started spewing flames. Our friend freaks, and runs up to kick the can away from all the fire and my brother and I, who were also on fire. More fire speads as my brother and I run and jump into our pool. That was a fun night.
Also, not me, but another one of my brothers stories:
He built a pretty decent potato gun back in the day. Nice piping, decent sized chamber. Anyway, normally we would launch stuff with only hair spray or some crap like that...not at this family party! He decided it would be cool to try it out with pure oxygen and acetone. He didn't put anything down the barrel at first, and a 6 foot flame shot out the end. "Whoa, I gotta see how far this sh!t can fire!" He rams a potato down into it, reloads it with MORE oxygen and acetone, and pulls the trigger...BOOM! A swear to you, a halo of flame surrounded him and our dead grandparents ghosts saved his life that day as the potato gun exploded in his hands. It put holes in our garage and I found shards of it 50 yards away. He escaped with a really bruised hand and some cuts on his neck.
