I saw this on a Facebook share (so this image is definitely not mine, if it is yours, please let me use it). It is quite an interesting set-up, I am not sure how long the set-up of the tree stump or log will hold the strength to prop up the frying pan, stove or pot that will be put up at the top of this set-up which will now be called the Swedish Fire Torch.
I found a video on YouTube that shows how exactly this can be done and it looks like a real easy and simple thing to do. Check out the video below to see how it is being done, as the narrator demonstrates from the beginning to the actual cooking itself. Cool stuff.
