Most campers and hikers will often find they need to constantly keep throwing large logs or branches on a fire to keep it burning for even 1 or 2 hours. And, if you fall asleep while camping, you can expect your fire will go out typically within 45 minutes to 1 hour later. This isn’t good if you need to stay warm. Or, you need to keep a fire going in wet conditions.
A Youtube user named “Doogly” created a simple video that will show you how to create what’s called a “Swedish torch,” or better put, a sustainable fire made with just one log. The Swedish torch legend was thought to originate from hobo, who was looking for an efficient way to stay warm during cold winters. So, he cut a small log as the video shows and stayed warm for many more hours versus a traditional campfire.
