PRIMITIVE ROCKET STOVE
We have all seen how to make a rocket stove out of cinder blocks or bricks but here is how you do it out in the woods with nothing but what nature gives you.
You can use this rocket stove to heat your food and because most of the heat is concentrated upwards, you can boil water in a very short amount of time. This rocket stove is also works as a torch to put around your camp or as a signal flare if you need to be rescued.
