Wasn’t sure what I was going to write about, but today I tested a new method of making fire using a bottle of water, which worked incredibly well (no need to carry condoms any more)!
I inverted the water bottle and held to the sun, and then placed a piece of True Tinder Fungus behind the water bottle at the point where all the suns rays were being focused
Here you can see the bright spot on the fungus which is the hottest point and you can see the grey area where the fungus is starting to burn.
Here is a close up picture of the fungus actually burning. Even with the week winter sun, it worked very quickly (within a few seconds).
