Step 3 Construct the cups

Ok, you have your forms and your materials so lets go to work.

You will use the first, second and third forms to make aluminum foil cups.

Once the cups are formed fold back the edges or use a pair of scissors or a knife to cut the edge of the first and second cups to make the heights of the cups about 1" to 1-1/2".

Make the second cup a bit shorter than the first by cutting off about 1/8".

Cut a circular (or other geometric shaped hole) centered in the bottom of the larger second cup about the size of a quarter or a little larger. You can increase the size after testing the results by burning a little alcohol. If you have enough pieces of aluminum you can use trial and error to find the optimum dimensions.

In the first cup cut out triangler sections about 1/8" deep around the top edge and about 1/8" to 1/4" apart. These will be the intake vents.

In the second cup cut out similar triangles about 1/2" deep and 1/2" apart. If you have a piece of aluminum that is big enough you can make its diameter a little larger than the cook pot and go all the way to the top instead of using cutouts for the exhaust ports.
