This is cool! These pictures show the easiest oil lamp in history! 3 things are necessary: an aluminum can; a cotton wick (any cotton cloth will work); bacon drippings (or something similar.) Just fill the can with drippings, reverse the pop-top, insert the wick, and wait for the drippings to harden into tallow. Easy!
