The evolution of the balloon has gone from sewn animal skins to stylish materials - bright, magnificent and durable. In this day it is a essential ascribe of every holiday. But initially, the utility of creating a balloon was from start to finish different.
The principal balls
Mentions of the earliest balloons were stilly in Karelian manuscripts. There was described the technique of their start from the integument of whales and bulls. Balls were also made from the bladder of pigs. In the annals of the XII century it was mentioned that balloons were set up in bordering on every Karelian family. There are legends that in this way people moved for everyone off-road areas. At the unvaried interval, the balls themselves were not darned strong: subservient to zephyr sway, the animalistic's lamina could rupture at any moment. But reliable statistics on the method of such repositioning between settlements has not been found.
The inception of the employ of rubber
In the XIX century, the English scientist Michael Faraday conducted experiments with gases in London. He intentional the pliancy properties of rubber. As a result, he came up with the viewpoint to make a rubber ball.
In 1824, he cut in default two circles from the uncured nugget, sprinkled them with flour on the exclusive, and blinded the edges with his hands. The arise was a baggage made of rubber, which Faraday filled with various gases, most time after time hydrogen.
Already in 1825, Thomas Hancock launched the tag sale of kits consisting of a bottle of limpid rubber and a syringe. Using these items, it was admissible to frame a ball yourself.
The fundamental balls made of vulcanized rubber, that is, of increased guts, were presented in 1847 past J. G. Ingram in London. They were already closer to what we used to see.
In 1889, the balls came from Europe to the USA. They cost 4 cents in the service of 1 piece. And in 1907, in Ohio, the coordination "Rubber Firm" began to make balls independently. Already in 1912, the actors's variety expanded, they began to produce oblong-shaped balls надуть шарики в дубае
At the beginning of the XX century, rubber balls became awfully amateur and were hardened on burg holidays. Proper to the gas clandestine them, they soared not susceptible the ground, which conquered people and caused direct delight.
Until 1922, the balloons were filled with hydrogen. They flew no worse than those that are now filled with helium. The problem was that hydrogen is explosive. And in 1922, at a urban district fete in Up to date York, USA, decorated with balloons, some unsung myself staged an explosion. Because of him, people and a major documented suffered, to which law enforcement agencies right away responded. Stuffing balloons with hydrogen was forbidden. Helium was chosen to supplant it, which is still euphemistic pre-owned an eye to these purposes. It is right and does not ignite below any conditions.
