Here is a good source of fire for cooking or even a source of light that can be carried in a small bug out bag or sitting on top of the fridge. No need to try and find dry wood or trying to get a fire going to cook things. It can be used over and over and put back into the bug out bag for use another day. Perhaps your house has lost power and your stove or microwave will not work, or you might be rough camping or on a back packing trip. Take a used up can of tuna or some can of similar size. Cut cardboard box into strips as wide as the can is tall and long enough to wrap in a circle filling the inside of the can. Take an unscented candle and melt it onto the cardboard or melt the candle in a pan and pour the wax inside the can till the cardboard is covered just below the top of the can. Let it cool till the wax is again hardened and your fire can is finished. Whenever you need a fire for cooking, light source, or some heat to warm up with just lite the cardboard with a match or a lighter. Hold a pan with food over the fire or maybe use a stick to hold whatever over the fire. Just like roasting marshmallows. When you are done with the fire hold something over the can to smother the fire. After it cools and the wax is hardened again just put it in your bug out bag to use again. Believe me this will supply many a fire when needed, You can't get a cheaper yet functional carry around fire source. I have three made up in different size tuna cans. Yes it does work very well. Beware using food on a stick because you might get some wax from the smoke on you vittles. The can on the right was used once to heat up a pan of beans.
