Here's the list of top 10 important inventions that were invented through accident or mistakenly lead process.
10. Microwave ovens
Percy Spencer, an engineer from the Raytheon Corporation was conducting a radar-related research project with a new vacuum tube. Spencer realized that the candy bar in his pocket began to melt during his experiments. He then put popcorn into the machine, and when it started to pop, he knew he had a revolutionary device on his hands.
9. Scotchguard
Patsy Sherman, a renowned American chemist, was assigned in a project of developing a rubber material which wouldn't deteriorate from jet African fuel exposure. Once she dropped a mixture on her shoe and noticed that one spot of her shoe is clean and bright but rest of it is stained and dirty. Later, with more research and experiment she turned this invention into this famous stain resistant component.
8. Teflon
In 1938, Roy Plunkett, a scientist with DuPont, was working on ways to make refrigerators more home friendly by searching for ways to replace the current refrigerant, which was primarily ammonia, sulfur dioxide, and propane. After opening the container on one particular sample he had been developing, Plunkett found his experimental gas was gone. All that was left was a strange, slippery resin that was resistant to extreme heat and chemicals.
In the 1940s the material was used by the Manhattan project. A decade later it found its way into the automotive industry. It wasn't until the '60s that Teflon would be used for its most noted application- nonstick cookware.
7. Matches
For more than 100,000 years, humans have been playing with fire. But no one could create a really easy way to start a fire until a British pharmacist tried to clean his stirring utensil. In 1826, John Walker was stirring a pot of chemicals when he noticed a dried lump had formed on the end of the mixing stick. Without thinking, he tried to scrape off the dried gob and all of a sudden, it ignited.
Walker wasn't interested in patenting the idea, so Samuel Jones copied the matches and sold "Lucifer." They were a little more practical than Walker's friction lights. Lucifers were shorter and came in a smaller cardboard box for easy carrying.
6. Saccharin (an artificial sweetener)
The familiar sweetener in the pink packet was discovered because Constantin Fahlberg, a researcher from Johns Hopkins University, forgot to do what even a high school chemistry student knows- 'always wash your hands'. He had spilled a chemical on his hands in the lab that caused his bread to taste very sweet. The researcher immediately requested a patent and mass-produced his product.
Luckily for dieters everywhere, he managed not to poison himself along the way.
