Through the History of China - Flying Chinese Flashlights

The place of the appearance of celestial torches belongs to the East. There they were from ancient times very much loved by the people. To us in Russia, such entertainment only comes and acquires fame.
The chronicles speak, for, in fact, the Chinese lanterns that appeared for the first time were used in 180-234, during the armed campaigns of General Zhuge Liang, he used them to infuse fears of enemies.
How did this happen in ancient times? Using a lamp with oil and a huge paper-made package. The design soared and the enemy was terribly afraid of what the divine beings thought on the side of the general.
Other historically evidences tell us that some scholar of antiquity Joseph Needham says that they belong to an even earlier time -. The sources mention that the sky lanterns were primarily intended to broadcast important messages between the various regiments of the army, and only later they were used in religious activities.

Writer and photographer Zhou Xin in 2005. He came out on a rather high line in the magazine of arts and entertainment in the competition held for journalists World Press, for having filmed a performance on one of the seashores of Thailand from five thousand Chinese lanterns rising above the horizon in honor of Memory of the victims of the earthquake in the Indian Ocean. So, the public increase in the number of desire balls has begun after that moment, and if to be specific - since 2006 in Europe.

Traditionally, the supporting structure or the frame of the product (Chinese lanterns) is made of light bamboo, in addition, an important element is installed in the lower part of the structure - the "engine" of this whole structure, or a combustible substance. There are at least two variants of its execution: either from thick paper impregnated with special combustible substances, in another case it is a cotton cloth that is impregnated with wax.

Another of the existing methods from which the combustible substance is made is combustible polymers. The dome, which is put on the frame, is made technologically from non-changing light piece of rice paper with the addition of mulberry tree, in turn, which are impregnated with specially designed substances. Make the shape of Chinese lanterns can be completely different: from the simplest cylinders, ending with the most incredible.

Calculation of the parameters of Chinese lanterns is easy enough. After all, it's easy to determine the temperature under the dome of a white sky lantern, then calculate the mass and then the density. So, you can determine and the speed with which our Chinese flashlight will go up.
Having a size of about a meter in height and weighing about 150 grams, such a flying object is gaining altitude of about 800 m in 10-18 minutes.
You also need to say about the safety rules when using desire balls. It can not be used closer than 5 kilometers to airports and fire-hazardous structures. Accordingly, it is undesirable to launch in windy weather.
