Thats a secret he wont share untl he has worked out a few flaws and has a patent, Yee. I know they're easy to make and cheap, and I have a few thought's on composition, but it's not my invention or I would freely share it. I don't like the amount of smoke generated by them, but they do dry out and ingnite soaked tinder and kindling. And they put out a good amount of light as well.
