No pics,won't need 'em. Take a coffey [<-- can't spell it,don't drink it either.]can,empty obviously. Preforate several large holes around the rim. a roll of cheap toilet paper.[Make sure there's more TP!] Pour in 1/4 bottle of rubbing alcohol,let it soak about 5 minutes. Light a piece of paper and drop it in. It produces enough heat to fry an egg in a thin skillet or warm a small hunting blind,it lasts 30-45 minutes.
