This reminds me of a caving trip I took in West Virginia with some church group when I was fifteen. We were wearing these helmets with chemically powered lanterns attached to them. There was a tiny hole in the center of the reflector. Gas shot out of this hole and it was lit to produce a very thin, intense flame an inch or so long.
Anyway, I was climbing along behind this girl with long, frizzy blond hair. Apparently, I must have leaned over a bit too far, because when I looked up, a strand of her hair was going up just like a fuse. Kinda like in your picture.
So I started slapping her on the back of the head to put out the fire. Naturally, this produced some puzzled exclamations from the girl in question. I informed her that I was just putting out her hair and that she should shut up and climb.
