2 Minute Stove For $1
As illustrated in my video, you can make this alcohol stove in only 2 minutes, using an empty soda can and a knife. This type of stove is called a chimney stove, because the air that enters throught the lower holes creates an updraft inside the can and accelerates the flame. The best fuel to use is Denatured Alcohol because it burns clean and complete. I used the 70% Isopropyl Alcohol in the video for 2 reasons: Cost; and because most people have it in their medicine cabinet. You can also use 50% Isopropyl Alcohol, but these Isopropyl Alcohols tend to be sooty and leave liquid behind after the flame expires.
Using liquid fuels can be hazardous, and the design of this style burner can be tipsy, so it would be prudent to do it outdoors, or, if indoors, perhaps set it inside a pan or tray in the event it should tip over. I invert an empty coffee can over the stove and cover it in order to extinguish it. Also, when you first light the stove, let it burn for a little bit so that the device can heat up before you place a cup or pan on top.
