Make Emotional Gift - Celestial Flashlights

Celestial lanterns , or a friend's favorite Chinese balls of desires, brought their traditions to the west from the countries of the rising sun, in those countries they are especially popular. In Russia, such paper flying luminous structures only become known.
Now they say that according to the chronicles it was discovered that for the first time the celestial lanterns were used by the armed forces of Zhuge Liang during his military campaigns and by such an original method they instilled fear of the enemy. These were the times around 180-234.
Zhuge Liang in his command used almost the same basic assembly scheme as it is today: a non-combustible package, like a torch, a lamp with oil was used. The enemy forces were gripped by horror, they imagined that some kind of divine power was on his side.
According to other evidence, the sky lanterns arose even earlier, around the third century BC, as Joseph Needham tells us. At first, the desire balls were used by the Chinese army to send orders, and later it turned into religious bases.

Not only in Asian countries, but also in the European part since 2006, one of the reasons for the massive appearance of sky lanterns in several past years was the beginning of an event in the town of Thailand on Khao Lak beach. It took place in 2005 and became a memory to the victims of the monstrous earthquake in the Indian Ocean in 2004. Then the photographer Zhou Xin or Ganjou Daly photographed a spectacular spectacle of five thousand sky lanterns launched in memory of the memory. And in this way, the journalist-photographer secured almost the first position in the influential magazine World Press.

Traditionally, the main construction or frame of the product is made of a light wood - bamboo, in addition to the frame structure, the actual motor device of this entire structure is installed, or simply a burner. There are at least two options for its production: either of thick paper, well impregnated with special combustible substances, or cotton cloth impregnated with substances from wax.

Flammable compounds are another option for making a burning substance. On the frame is put on a dome, which is usually made of rice paper, impregnated with a special non-flammable means, just as a mulberry tree can be added . The shape of the carcass and the dome can be made completely different - as the simplest variant of spherical and cylindrical, so various others.

The principle by which a celestial flashlight soars up is extremely simple. The burner heats the air mass under the dome of the sky lantern to temperatures above 100 degrees Celsius. There is an increase in the volume occupied by air, for this reason, its part comes out, the air density of the inner part begins to decrease, so we get a soaring heavenly flashlight.

Calculation of the parameters of Chinese lanterns is quite simple. After all, it is not difficult to determine the temperature under the dome of a celestial flashlight, then calculate the mass and finally the density. So, you can measure and the speed with which our desire ball will rise.
A celestial flashlight typically has a mass of about 130 g, with about 1 meter in height. The flight time is about 10-15 minutes, this is enough to reach a height of up to thousands of meters.
I would also like to note the rules for the safe use of Chinese lanterns. It can not be used close to airports and is also very close to fire-hazardous structures. In addition, it is undesirable to shoot a flashlight in a windy weather.
