They were the first people in history to make animal sculptures out of inflated cat bowels and present them to the gods as sacrifices. Professor Michael Faraday invented the first rubber balloons in 1824 for use in experiments on hydrogen at the Royal Institution in London. Balloons made their world debut at the Paris Exposition of 1889. They resembled large hot air balloons, which had been around since 1783. The art of balloon sculpture began in the 1920's, but didn't become popular until skinny balloons were invented after World War II and marketed in the 1950's.
