Toy balloon in "Swiss Family Robinson" (1813) and in "Moby Dick" (1851). 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..." Faraday made his balloons by cutting round two sheets of rubber laid together and
Balloon rocket that occur in the opening as the air escapes, causing it to flap rapidly and disperses air outwards in random direction. Near the end of its deflation, the balloon may suddenly shoot quickly in the air shortly before it drops down, due to the rubber rapidly squeezes out the remaining air inside as it reaches the inclination to return to its uninflated size. The flight altitude only amounts to some metres, with larger or lighter balloons often achieving longer flights. In addition, a cylindrical-shaped (or "airship") balloon may have a more stable flight when released. If the balloon is inflated
