* Coffee can
* Can opener
* Tin snips
* Drill and drill bits
* Metal coat hanger
There are many methods that could be used to build this stove. Instead of tin snips a chisel or a flat screwdriver could be used to cut into the can.
We use a metal coat hanger to build rods which will help hold up the cooking pot.
The top side of a coffee can is already opened. If the bottom is left on, we would not need the can opener for this project. Just make sure to drill extra holes in the bottom area of the can so the tinder gets proper ventilation.
We then used the tin snips to cut a small door. This opening will be used to feed the fuel for the fire.
We tried to use a can piercer (triangle can opener) to make the holes instead of a drill. In an attempt to save money companies are using thinner cans and this is what happened. This could possible be avoided by leaving the bottom side of the can untouched. The added rigidity should allow the use of a sharp triangle can opener to make the ventilation holes.
For this project we used a drill with a 1/2 inch drill bit to make the larger holes at the bottom of the can. If a drill is not available, the can needs to be supported by a piece of wood and a screwdriver or knife can be used to punch holes into the can.
Four more holes need to be drilled along the top side. The holes will allow us to push the wire pieces we built using the coat hanger. Use wire cutters, a multi-tool, or just bend the hanger back and forth until it breaks.
Now you can see how the two wires will hold up our cooking pot or smaller can. This is just another way to adapt to the situation. Water can be boiled in a beer can or empty food can.
Next we started a small fire using leaves and twigs. Normally we would allow enough time to build a bed of coals. Here we started attempting to boil the water as soon as we started the fire. We wanted to time the process.
We placed the pot on top of the stove and within minutes we started to see steam. We would want to wait until the water comes to a roaring boil. We added small twigs and sticks through the square hole we cut into the can using the tin snips.
A little over six minutes and we had boiling water. The temperature on this day was eighty degrees Fahrenheit. During cold conditions we would want to allow the coals to build up and a longer time to boil.
