The evolving of the balloon has gone from sewn unrefined skins to stylish materials - bright, magnificent and durable. In the present climate it is a mandatory put down to of every holiday. But initially, the designedly of creating a balloon was completely different.
The basic balls
Mentions of the earliest balloons were stilly in Karelian manuscripts. There was described the change of their start from the flay 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 found in almost every Karelian family. There are legends that in this withdraw people moved everywhere off-road areas. At the very conditions, the balls themselves were not altogether potent: under feeling pressure, the monster's shell could puncture at any moment. But safe statistics on the method of such repositioning between settlements has not been found.
The creation of the employ of rubber
In the XIX century, the English scientist Michael Faraday conducted experiments with gases in London. He studied the elasticity properties of rubber. As a upshot, he came up with the hypothesis to give rise to a rubber ball.
In 1824, he degrade in view two circles from the uncured flock together, sprinkled them with flour on the at bottom, and blinded the edges with his hands. The end result was a portmanteau made of rubber, which Faraday filled with various gases, most ordinarily hydrogen.
Already in 1825, Thomas Hancock launched the reduced in price on the market of kits consisting of a fiasco of fluid rubber and a syringe. Using these items, it was practical to beget a ball yourself.
The first balls made of vulcanized rubber, that is, of increased strength, were presented in 1847 alongside J. G. Ingram in London. They were already closer to what we old to see.
In 1889, the balls came from Europe to the USA. They price 4 cents in the service of 1 piece. And in 1907, in Ohio, the organization "Rubber Company" began to make balls independently. Already in 1912, the company's assortment expanded, they began to create oblong-shaped balls

At the origin of the XX century, rubber balls became awfully ordinary and were hardened on see holidays. Due to the gas inside them, they soared above the sod, which conquered people and caused direct delight.
Until 1922, the balloons were filled with hydrogen. They flew no worse than those that are right away filled with helium. The problem was that hydrogen is explosive. And in 1922, at a city fete in Different York, USA, decorated with balloons, some uncharted child staged an explosion. Because of him, people and a foremost proper suffered, to which law enforcement agencies without delay responded. Innards balloons with hydrogen was forbidden. Helium was chosen to repay it, which is still used for these purposes. It is safe as the bank of england and does not ignite controlled by any conditions.
