Stranded in the snow with no stove? Take a stick and pack snow tightly around it. Roll the whole thing into a firm snowball. Then stand it upright and compress the snow well before pulling the stick out. Next, make a second hole at the bottom and connect it to the first one. Once you light kindling and place it inside, the snow shields the flame from wind, while the fire pulls air through the lower vent. Even as the snow slowly melts, the stove lasts long enough to boil water and make hot coffee
