With the advent of the ability to attach a plastic bottle filled with water to the stove for heating, its destruction is observed when high temperature reaches - and this may seem quite logical, but this does not happen in real life! While the water is in the container, it plays the role of the cooler, and therefore the bottle does not light up and melt, moreover: it really can boil water in it - if the bottle is complete and correctly fixed over fire, then it will not even get serious damage, but if not, it can deform. This is a simple physics, such an experience can even be carried out with a thick birch bark, adding it as follows: https://www.youtube.com/watch?v=Xywb1beSDWs (by the way, here you have an idea for an “impromptu disposable dishes for boiling water” - from birch bark!) This “trick” is known to many survivors, and In order not to be unfounded, I attach links to these videos where the water in a bottle is boiled directly in the fire: https://www.youtube.com/watch?v=JnyxlHJQ0ew Also take a look here: https://outdoorwilda.com/boiling-water-in-a-pet-bottle/ It would be nice to revise the current situation with this issue and implement this game mechanics: on the one hand, this will add a sort of credibility, and on the other hand - significantly facilitate and diversify the players survival at its beginning (of course, with frequent boiling the bottle will not be “eternal”, but you can “create a game convention” and give players the opportunity to use boiling in a plastic bottle at least once - “for the most extreme case” , and her condition when boiling will deteriorate, while trying to put an empty bottle on the fire - of course, it will be destroyed)
