Modern bushcraft: Man makes treehouse bivouac from plastic wrap
A Ukrainian man demonstrates how to make a treehouse bivouac from cling film.
By running the plastic wrap between nearby tree trunks, he creates a foundation on which to support a bed, roof and even walls for the improvised accommodation.
If you happened to find yourself in a swamp with a nothing but a very large roll of cling film, this knowledge hack could ensure you get a clean and dry night's sleep.
Given how much it requires, don't forget to take the plastic with you when you move on though.
