Making fire in the desert with sunlight, making fire with a plastic bottle with a little water.

The main natural resource desert is bright sunlight. However, after sunset, due to the lack of cloudiness, the earth quickly gives off the received heat. Moreover, the temperature here can drop very sharply. Therefore, if at night you do not follow the route in the desert, you need a heat source to keep warm. To do this, even in the daytime, use bright sunlight to fire in the desert. 

Making fire in the desert with sunlight, making fire in the desert with a plastic bottle with a little water.

All you need to make fire in the desert is a clear plastic bottle with a little water or other liquid and a few sheets of newspaper. Dark ink on paper in this case acts as a flammable substance. Instead of newspaper sheets, you can use dried leaves and grass or fragments of dry branches as a kindling. In most deserts you can find a lot of flammable brushwood.

Use the convex end of the bottle to refract or change the direction of the sun. When light passes through your homemade lens, its rays can be focused at one point. There will be concentrated energy, leading to the heating of this point. This device can increase the power of sunlight to such an extent that the newspaper turns red and then begins to smoke. Turn it a little under the lens so that instead of smoke, a flame appears.

Desert fire using a plastic bottle with a little water.

1. Take a clear plastic bottle and a few sheets of newspaper.
2. Focus the sunlight on the newspaper in the form of a speck of small diameter, for this:

Hold the top convex end of the bottle above the newspaper.
Slowly move the bottle away from the newspaper.
Select the angle of the bottle and the distance to the newspaper so that the sunlight focuses in the form of a hot spot of small diameter.
Printing ink on a newspaper acts as an ignition element. As a result, the paper lights up after a few seconds.

After the paper begins to smoke and a light appears, add another layer of paper. Wave over it or blow on it so that the flame ignites. If necessary, add more newspaper sheets or other kindling.

The intensity of sunlight in the desert largely depends on the time of day and season. The reception described above will work better for a traveler at noon at the equator than for an unlucky tourist who was in the wilderness in the Northern Hemisphere at the height of winter.

A simple glass bottle can also be used for this purpose. If the glass itself is thick enough to refract sunlight, then you can do without liquid. In a plastic bottle, the liquid serves to intensify the process of making fire in the desert.
