The Coffee Log

Just went to the health food store and saw the coolest thing. Firestarters made from coffee grounds. What a great idea. It was a log of compressed coffee grounds kind of like the duralog type product. I use these things when I'm camping or starting fire in the outdoor firepit. Haven't tried the coffee one yet, but I'm sure they smell better and I guess their better for the environement too. I'll give it a shot. Wonder what else you could use to make those logs?
