"coffee can" trailstoves(aka hobo stoves) are simple.You need to cut about three holes near both the top and blottom .This creates your draft. I like the holes close together for those windy nights.They will get WHITE hot,so use a brick or rock(not from water source as they will explode) underneath.If you clear the soil of debri,the heat will destroy all nutrients.I carry a "'fire cloth" for all my campfires.This is a small space blanket on steroids for zero impact camping.You will have to keep your hobo stove clear of ash buildup.<br><br>
