Lightweight Backpack Stove
You can make this simple back packing stove with little cost ($0.25 US).
What You'll Need
Step 1For the base, neatly cut one can about 1 1/2" (3.5cm) from the bottom. For the top, cut the other can about 1" (3.5cm) from the bottom.
Step 2Drill a number of holes (18-30) around the edge of the top and in the center as shown; use a 1/16" drill bit.
Step 3Fill the base with Perlight, just more than half full.
Step 4Make 6-8 vertical cuts around the top. Make the cuts up to but not over the rounded edge. Slowly press the top into the bottom. (A small board can help make it even.)
Step 5Fill the stove about half full of alcohol. Light the burner by slowly moving a match or lighter over the edge of the burner.Note:If it does not stay lit, tip the burner up to leak some fuel into the rim and re-light. Hold it until it stays lit or gets too hot.
