The progress of the balloon has gone from sewn animal skins to stylish materials - promising, beautiful and durable. For the time being it is a essential attribute of every holiday. But initially, the purpose of creating a balloon was completely different.

The basic balls
Mentions of the first balloons were silence 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 rest in wellnigh every Karelian family. There are legends that in this withdraw people moved for everyone off-road areas. At the very conditions, the balls themselves were not really smelly: lower than drunk zephyr pressure, the animal's strip could burst at any moment. But reliable figures on the method of such movement between settlements has not been found.

The beginning 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 arise, he came up with the idea to create a rubber ball.

In 1824, he assassinate interrupt in view two circles from the uncured nugget, sprinkled them with flour on the reversed, and blinded the edges with his hands. The end result was a bag made of rubber, which Faraday filled with various gases, most commonly hydrogen.

Already in 1825, Thomas Hancock launched the car-boot sale of kits consisting of a bottle of liquor rubber and a syringe. Using these items, it was realizable to frame a ball yourself.

The fundamental balls made of vulcanized rubber, that is, of increased strength, were presented in 1847 through J. G. Ingram in London. They were already closer to what we occupied to see.

In 1889, the balls came from Europe to the USA. They rate 4 cents in the service of 1 piece. And in 1907, in Ohio, the system "Rubber Following" began to neaten up balls independently. Already in 1912, the party's assortment expanded, they began to cause oblong-shaped balls balloon arch garland kit

At the beginning of the XX century, rubber balls became very current and were used on megalopolis holidays. Owed to the gas clandestine them, they soared insusceptible to the compass basis, which conquered people and caused sincere delight.

Until 1922, the balloons were filled with hydrogen. They flew no worse than those that are at the moment filled with helium. The refractory was that hydrogen is explosive. And in 1922, at a conurbation anniversary in New York, USA, decorated with balloons, some uncharted myself staged an explosion. Because of him, people and a foremost proper suffered, to which law enforcement agencies without delay responded. Filling balloons with hydrogen was forbidden. Helium was chosen to put in place of it, which is still euphemistic pre-owned concerning these purposes. It is protected and does not ignite beneath the waves any conditions.
