Teflon: In the early 20th century, Roy Plunkett, a chemist, worked in DuPont (an American chemical company), stumbled on not chemically react, do not stick chemicals during their experiments with refrigerants in which deliberately tried to find non-toxic chemicals for use as a coolant. After some time he kept tetrafluoroethylene (TFE) in small cylinders in a gas, the frozen state, the gas suddenly turned into a waxy substance. Further experiments showed that the wax had some interesting properties, some of which is well known: it is one of slippery substances known to man. Dupont quickly patented it, and today, this substance is known to us as Teflon.
Self-adhesive leaves notes: In 1968, Spencer Silver, a chemist who worked at 3M (US diversified innovation and production company), came across a sticky substance "low tack", at a time when he was trying to make a super strong adhesive for use in aircraft. Silver thought the low tack adhesive which disappeared without a trace, and was to some extent reusable, was helpful, but no one agreed with him. He advocated its use for 5 years before someone in 3M heard it, but even then it took another 7 years of improvements, of which 3 have been there, where they were created, self-adhesive sheets for notes, but they were intended only for internal use as management 3M believe that they have very little commercial value. Finally, they were subjected to the test leaves for notes on a few test markets, but they suffered a setback in four test cities. No one wanted to buy them. Management tried to stop these futile attempts by giving these leaves many companies free of charge. After that, everyone wanted to buy them, and self-adhesive leaves today one of the most purchased goods for the office in the world.
Plastic: In the early 1900s, when it came to insulation, shellac was a popular material. But in view of the fact that it was made of beetles in Southeast Asia, the material has been subject to an expensive import. For this reason, the chemist Leo Hendrik Bakeland believed could earn some money by producing an alternative product. What he came up with, however, was formed by a material that could be heated to very high temperatures, without any Amendments - plastic.
Microwave: Every bachelor in the world should be grateful to Percy Spencer, a true genius, an orphan, is not over even high school (although at a mature age, he was engaged in self-study and achieved amazing results by studying all possible calculations in the industry, and has become one of the world's leading experts for the manufacture of equipment for radar). At the time when he worked as a specialist in radar, he often was near microwave emitters and stood in front of one of them, when he noticed that the chocolate bar that lay in his pocket melted. Shortly thereafter, he spent a few more experiments, and eggs which have undergone one of them, and did explode, and realize the full potential of the microwave to prepare food. It was 1945, and the world, or, more precisely, the kitchen, was no longer the same.
