The growing of the balloon has gone from sewn unrefined skins to stylish materials - bright, magnificent and durable. For the time being it is a compulsory ascribe of every holiday. But initially, the designedly of creating a balloon was thoroughly different.

The first balls
Mentions of the ahead balloons were silence in Karelian manuscripts. There was described the change of their creation 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 in wellnigh every Karelian family. There are legends that in this withdraw people moved for everyone off-road areas. At the changeless chance, the balls themselves were not very steady: under feeling make, the beast's strip could puncture at any moment. But infallible matter on the method of such action between settlements has not been found.

The inception of the from of rubber
In the XIX century, the English scientist Michael Faraday conducted experiments with gases in London. He studied the pliancy properties of rubber. As a result, he came up with the viewpoint to give rise to a rubber ball.

In 1824, he cut in default two circles from the uncured preponderance, sprinkled them with flour on the inside, and blinded the edges with his hands. The result was a baggage made of rubber, which Faraday filled with various gases, most ordinarily hydrogen.

Already in 1825, Thomas Hancock launched the sale of kits consisting of a fiasco of limpid rubber and a syringe. Using these items, it was admissible to invent 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 second-hand to see.

In 1889, the balls came from Europe to the USA. They rate 4 cents for 1 piece. And in 1907, in Ohio, the system "Rubber Company" began to neaten up balls independently. Already in 1912, the fellowship's set expanded, they began to cause oblong-shaped balls baloon store

At the beginning of the XX century, rubber balls became exceptionally amateur and were used on burg holidays. Proper to the gas preferred them, they soared not susceptible 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 now filled with helium. The problem was that hydrogen is explosive. And in 1922, at a urban district festival in Advanced York, USA, decorated with balloons, some unsung child staged an explosion. Because of him, people and a prime official suffered, to which law enforcement agencies promptly responded. Innards balloons with hydrogen was forbidden. Helium was chosen to supplant it, which is allay used seeking these purposes. It is safe as the bank of england and does not ignite controlled by any conditions.
