My nephew was telling me about a handy little stove you can make out of a soda can. He's made a couple of them. They're small, lightweight, and put out a lot of heat. (Great for hiking.) Here's the link to the site he found: http://en.wikipedia.org/wiki/Beverage-can_stove. Thanks for sharing Ben!
UPDATE: Ben gave me his first prototype. (Thanks Ben!) He demonstrated how it works. "AMAZING" is pretty much the word to describe this little gadget (and my nephew Ben!)
