It is called ‘The Swedish Torch’ and it is absolutely brilliant.
Said to be created by an early train hopper to stay warm in between jumping trains, this simple hack will allow a single log to burn for hours upon hours.
Youtuber Doogly put the legend to the test and created his own Swedish Torch and it actually worked!
You simply take one log, make two cuts across the top in a cross-hair pattern and go roughly 3/4 of the way down the log with the cuts. Start a small fire on top, airflow through the cuts will fuel the fire on top. Once the small fire on top burns down, coals will fall through the slits and the log will begin to burn from the inside out, creating a long lasting fire.
Cut the log flat on both side and you will be able to place a cooking pot on top and cook all of your meals directly on the fire! So cool!
