After we featured how to make an emergency fire starter out of a t-shirt, we've gotten a few other tips on other useful flammables. With a few common household items, though, you can also create a pretty handy stove.
The t-shirt and Vaseline ideas are both great in an emergency, but if you're, say, out camping and have a few more items with you (namely a can, cardboard, and some wax) or you've done a little preparation ahead of time, you can make a pretty handy emergency candle or even a nice little heater. The "Buddy Burner," as it's called, is especially nice because it is pretty immune to moisture and, unlike propane, will light at fairly low temperatures. Plus, they should burn for about 2-3 hours, which isn't bad considering its size and weight. Thanks, Bob!
