10 inventions have appeared by chance
Thomas Edison said - "Everything comes to those who work and knows how to wait." But not always, progress is the goal. Some great ideas come to mind quite by accident. You will find 10 of inventions that were created by accident.
In 1942, the American physicist Dr. Harry Coover was trying to separate the clear plastic for optical sights portable weapons. he worked with cyanoacrylate, which tightly glued test materials in the course of the experiment. But only after 6 years, Dr. Coover realized the full potential of this substance, which does not need any pressure or heat. It was created as superglue.
Interesting fact - during the Vietnam War, superglue used to arrest bleeding in open wounds. That's how the invention which was to improve the weapons saved many lives.
The American physicist Spencer Silver invented the glue, but the self-adhesive sheets for notes were created by Arthur Fry. In 1968 Silver was trying to create the ideal glue for paper handling, which could hold the paper on the surface, but not strong enough to be able to remove the paper without tearing it. In addition, he had to be sticky reusable.
True to the company where he worked Silver nobody was not interested. Until Arthur Fry did not use adhesive for bonding of bookmarks in the hymnal. It was he who suggested the use of a substance to create a reusable adhesive tabs. So the idea has gained popularity.
3. Inkjet printer
Canon company engineer accidentally put red-hot soldering iron on the handle. And when the ink ran down the idea to create an inkjet printer.
Dynamite opened Alfred Nobel. When he worked on nitroglycerin, he tried to make it more stable, to avoid accidental explosions. Vial of the substance fell to the floor, where there was a lot of sawdust. Sawdust stability and gave a small bubble is exploded. Nobel formula improved by adding silica to nitroglycerin. And there was dynamite.
English chemist Robert Chesebrough in 1859 noticed that many of the oil industry workers complain of a waxy substance - "wax" that accumulate in the pipes of oil pumps. Chezbro immediately took the matter sample and began experimenting. It turned petroleum jelly perfectly heals wounds and cuts. Chemist gave him the name "Vaseline" - (German "Wasser" -. Water and the Greek "elaion" -. Oil). The range of application of Vaseline was then wide - from carpet cleaning to cleanse the nose. The author is so believed in the miraculous powers of Vaseline that all his life he ate a spoonful a day. He died at 96 years old.
The initial purpose of Viagra - the treatment of angina. But when producing pharmaceutical company Pfizer has studied the side effects, it is found that high blood pressure does not drop and the subjects appear excellent erection. So the company changed the test and race began to explore erectile dysfunction and exposing it to Viagra. In 1998, the Administration of Quality Supervision approved medication and since then, many men began to celebrate life
7. Stainless steel
English metallurgist Harry Brearli tried to create a fusion of stainless steel for the production of weapons.
Stainless steel has appeared when he mixed with 12.8% chromium 0.24% carbon. the resulting alloy is resistant to acids, even vinegar and lemon juice. Later, the inventor realized that the resultant alloy is ideal for the cutlery that are made of silver and carbon steel and gradually came unusable due to corrosion.
diethylamide d-lysergic acid was discovered by Swiss scientist Albert Hofmann, who was trying to create a drug relieves pain during childbirth. The resulting material seemed to him not remarkable, and he put it on the shelf. In 1943, while working with the material without gloves and accidentally received a large dose of the substance, he realized the true properties of the compound. He felt a "continuous stream of fantastic pictures, extraordinary shapes with intense kaleidoscopic play of colors."
9. The teabag
A trader at the New York store Thomas Sullivan decided that selling tea in silk bags will be much more convenient and tea sales skyrocketed. It turned out that buyers mistakenly omitted the full bags into the boiling water, and the result they like.
In 1946, Percy Spencer, an engineer tested the magnetron emits microwave radiation. During the tests, the chocolate melted in his pocket. Percy suggested that this was due to the magnetron and placed near the instrument for grain popcorn. After receiving popcorn, Spencer decided to cook an egg, but it exploded. All this led him to believe that the low-frequency energy helps to quickly cook and a year later appeared the first microwave oven.
