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
James Marsh (chemist) of a milligram of arsenic. He first described this test in "The Edinburgh Philosophical Journal" in 1836.
