Life hacking. How to boil water without dishes

[DARPA]

This post will be useful to anyone who goes camping in the woods, in the mountains, picnics, etc.
In it, I talk about how to get into the field boiling water for tea, coffee or cereal fast food, if you do not bring any pot or kettle or pan, or even clubs, which could heat the water.
All we need to do - fire and water.
The method is very simple and convenient, he taught us in the course of survival during a special training Combat Camera.

2. Going to a short hike, we usually do not take with kettle, pot or pot without planning boil water for tea. But sometimes it happens that, or hike is delayed, or the weather deteriorates, or someone feels unwell, or just turn the situation so that it is necessary to stop for a rest. From tea in camp no one ever refused, and sometimes it is extremely necessary to keep warm. What to do if you need hot water, and heat the water is not what?
In fact, the heat it has what. After all, we brought it in something with him? Typically, water is we take in plastic bottles - they are both easy and practical.
Therefore, we boil water in a plastic bottle ...

3. Kindle Fire, completely fill the bottle volume with water and gently put it in the middle of a campfire.
Moreover, in order to boil 0.5 liters of water, fire is needed is quite small, it will be enough just a dozen small dry twigs. If you need to boil more water, better to do it in a few taps, you can use a bottle of large volume, as the water in it will boil a lot longer and a bottle can greatly deformed

4. All leave a bottle of water in the fire and wait for just two or three minutes.
You do not have to worry, the bottle melts !!!
Why is that?
Referring to the school course in physics. What is the boiling point of water? That's right - 100 degrees Celsius or greater degree. Then it begins to evaporate. Melting plastic PET - 260 degrees, i.e. significantly higher. Being in the fire with water inside, plastic just can not warm up to the melting point. Water, in fact, it cools to 100 degrees.
So while the water in the bottle, it does not melt and will be fine for you to perform the function of the kettle.

5. Before the water boils, it is necessary to remove the cork from the bottle (in principle, it can not be worn from the beginning). If left, the unscrewing can be seriously burned, because boiling water spill due to increased pressure in the bottle

How to get a bottle with boiling water from the fire?


And especially do not get carried away, after all plastic ..

UPD for a reason to harm the plastic bottle.
The material from which made plastic containers for water: PET (polyethylene terephthalate or polyester) - a polymer resistant to the heat (melting temperature - 260) and to the effects of chemical agents. Act on it only the strong alkali (sodium hydroxide or KOH). So that the negative impact on the critical water is not.
