                           It’s all hot air!
    For hundreds of year, human beings have been deeply interested in the idea of flying, but it was only in the eighteenth century that a piece of practical equipment was designed to achieve this aim. The French brothers Montgolfier observed that paper bags filled with smoke tended to rise. From these small beginnings, they developed the first hot air balloon, and the first manned balloon flight took place at Versailles in 1783.
    Almost at once, ballooning became very popular, but it was the gas balloon which became more widely used than the hot air balloon. The gas balloon in turn was replaced by the airship, which gave way to the more reliable aeroplane at the beginning of the twentieth century. But the hot air balloon never died out completely, and during the 1960’s, using new materials and a safer method of producing hot air, it actually took off again.
    By the 1980’s, marketing managers had realized that balloons made wonderful advertising boards and soon the skies were full of brightly colored and excitingly shaped advertisements for everything from butter to shoes.
