BALLOONS
Posted by levfra on April 11, 2008
The first rubber balloons were made by Professor Michael Faraday in 1824 for use in his experiments with hydrogen at the Royal Institution in London. The caoutchouc is exceedingly elastic’, he wrote in the Quarterly Journal of Science the same year. `Bags made of it…have been expanded by having air forced into them, until the caoutchouc was quite transparent, and when expanded by hydrogen they were so light as to form balloons with considerable ascending power. Some balloons are even made out animal bladders before rubber ones were invented. Another interesting kind of balloon is the hot air balloon. The Montgolfier brothers, born in Annonay, France, were the inventors of the first practical balloon. The first demonstrated flight of a hot air balloon took place on June 4, 1783, in Annonay, France. Joseph and Jacques Montgolfier, paper mill owners, were trying to float bags made of paper and fabric. When the brothers held a flame near the opening at the bottom, the bag (called a balon) expanded with hot air and floated upward. The Montgolfier brothers built a larger paper-lined silk balloon and demonstrated it on June 4, 1783, in the marketplace at Annonay. Their balloon (called a Montgolfiere) lifted 6,562 feet into the air.
