I have seen the lamps made in orange halves and the Crisco candle and even the alcohol in a paint can heater but then I saw this one and it is a little different. It is made with things that just about everybody has right in the kitchen and according to the directions it will burn for about 2 hours. If you ever had a power outage and were caught without candles or lanterns you may just have these items around and you could make these and at least have light.
