Inflatable latex rubber balloon, (the most common balloon) was Michael Faraday in 1824, via experiments with air and various gases. Inflatable castles and similar structures are temporary inflatable buildings and structures that are rented for functions, school and church festivals and village fetes and used for recreational purposes, mainly used by children. The growth in popularity of moonwalks has led to an inflatable rental industry which includes inflatable slides, obstacle courses, games, and more. Inflatables are ideal for portable amusements because they are easy to transport and store. The name given to such structures varies. They have been marketed with such
Rubber elasticity This phenomenon caught the attention of the English physicist John Gough. In 1805 he published some qualitative observations on this characteristic and also described the dependence of the tensile stress on temperature. By the mid nineteenth century, the theory of thermodynamics was being developed and within this framework, the English mathematician and physicist Lord Kelvin showed that the change in mechanical energy required to stretch a rubber sample should be proportional to the increase in temperature. Later, this would be associated with a change in entropy. The connection to thermodynamics was firmly established in 1859 when the English physicist James
