There are situations when you need to light a fire, but there are no matches or lighters at hand, and even the weather leaves much to be desired, for example, it is pouring rain. But you can get out of the situation. True, the method is more suitable for motorists, or the necessary ingredients should always be in a backpack.
To start a fire, you will need a rag, no matter what - a rag, an old T-shirt or T-shirt, and so on. In addition, you need potassium permanganate, which is in almost every first-aid kit in the car (if, of course, you complete it yourself), and a small amount of antifreeze.
The last ingredient is usually found in any car as well. Drivers are thrifty people. This liquid is probably in the trunk.
The process itself is as simple as possible. A small amount of antifreeze is poured onto a rag and potassium permanganate is poured on top. The latter also need a little. The rags need to be rolled up a couple of three times and wait a few seconds. A reaction occurs, as a result of which, after ten seconds, fire appears.
It will be no less interesting and useful to find out how to make a stove from a simple log that will burn for 5-6 hours.
