I have been meaning to ask this here, and the Tomb Raider Light Stick Thread reminded me about it...

In various movies, I have seen people use what looks like some kind of micro flare that was only about two or three inches long... It looked like they struck them like a match and then they burned for about a minute or two...
I was first reminded about these the first time I lit off a REI weatherproof match, and the thing looked like a flare...
I was thinking that, seeing as how you cannot get much better than a flare for fire-starting in the rain, that some of these(they looked smaller than cigarettes), would be a great way to get a fire started in WET areas...
They looked metallic, and MAY be some kind of magnesium rod with an igniter attached...
Anyone know anything about these???
