I was leaving a doctor's appointment and walking across the lobby to the front door of the building. There were people all around me (I mention this because a friend of mine insisted at the time that it was a hallucination), and they witnessed it as well. My purse was unzipped, and as I was walking to the door, I looked down and began to reach in for my keys. I saw a flame coming out of my purse, which was a small, leather purse that looked like a bladder. I gasped and threw it to the ground. I should mention that there was nothing flammable in the purse. Other people stopped to watch, and the flame grew to about 9" from the top of the purse. I kneeled down and swatted at the purse, and blew on it, and after a few seconds it stopped burning. I shrugged at the other people, and we all kind of laughed, and then I picked up my purse and looked inside - I had my wallet in there, and money, and wanted to see how bad the damage was. Nothing was burnt, or singed, or even hot!
So... I'm not sure that is actually combustion, because nothing was destroyed. But it was odd, to say the least.
