In the 30s of the 19th century, Europe and the United States saw the real charm of having dry feet. Shoes made from South American resin named caoutchouc, did not let water through, but had a significant disadvantage – on a hot day, the resin turned into porridge. With time, caoutchouc began to be applied in construction and many other places, but all its advantages melted in the sun – literally. Having barely been born, the rubber industry threatened to get thrown off the cart, but then inventor Charles Goodyear came to its rescue. He was not burdened with knowledge, but full of passion; he mixed raw resin with everything that came into his hand: salt, pepper, sugar, sand, castor oil, even with soup, in the hope of finding a good combination. Patience and work have worn out the need and failures: Goodyear received a patent and fame, and humanity received rubber: erasers, balls, wire insulation and soft running machines.
