Small Backpacking Stoves - Alcohol (HEET)

I made these out of pop cans for camping trips/hiking.  They offer an inside fuel chamber and tiny fuel vents.  One ounce of fuel (HEET) will boil two cups of water in five minutes.  Perfect for warming soup or making coffee. When burning many at a time, various uses are offered all at the same time - making soup, tea, and warming rocks to be used as hand-warmers.  I made little bags to hold the rocks, which can also be put inside boots, to warm the toes on a winter morning.
