This is a list of recommended tools and materials. Two soda cans, scissors, pliers, pocket knife, glue, and wick material.
Step 2: Step 1 - First Cuts
First step is to cut the cans, you will be using the bottoms of the cans mated together to form a fuel reservoir and burner. The first image is for reference. You can make the reservoir larger but the larger it is the harder it is to get the fuel to wick unless it is a thin fuel. Using the pocket knife puncture the cans about an inch from the bottom and use scissors to finish cut and to clean up the edges.
Step 3: Step 2 - Building Burner
Punch a slit into the center of one can bottom using a pocket knife. Then using the thumbtack punch holes around the slit to serve as fill holes. Be sure to punch at least one hole on the upper rim to work as a vent when filling. For the wick I used an old sock that I cut into a strip and folded over.
Step 4: Step 3 - Mating Cans
Now force the two cans together my inserting one into the other. Working with this short of cans with usually cause some crinkling but that is okay. Beware that when the bottom can rim meets the top of the other can it will usually cause the bottom can to rip. Next add glue to the mating rim to seal be sure to get glue into the crinkled spots. I use gorilla glue because it is strong and expands in the cracks. I have also used JB weld on similar projects. Now the burner/reservoir is complete.
