Sternos are a little aluminum cal used for mobile food warming, like BBQ beef sandwiches on Polynesian comedy night. You pop off the lid and there is neon purple goo inside in which you throw a lit match. Whatever the purple stuff is it burns for about three hours. You put it underneath the food so it stays hot. Then you throw it away. I'm just thinking, that it would be pretty useless if the substance of my life was like purple goo from a sterno.
