10 inventions that have appeared by chance

May 14, 1878, was patented trade mark "Vaseline". All known cosmetic and therapeutic agent invented and patented emigrated to America the English chemist Robert Chesbro. In this invention the scientist "helped" the oil.

And we decided to recall other famous and undeniably useful inventions that were created accidentally.

Thomas Edison said "Everything comes to him who works and knows how to wait." But not always progress is the goal. Some brilliant ideas come to mind quite by accident.

1. Superglue

In 1942 the American physicist Dr. Harry Coover was trying to separate the transparent plastic for optical sights portable weapons. In the experiment, he worked with cyanocrylate, which is tightly glued test materials. But only 6 years later, Dr. Coover realized the full potential of this substance, which does not need any pressure or heat. This was created superglue.

Interesting fact — during the Vietnam war, super glue was used to arrest bleeding in open wounds. So an invention which was to improve the weapons saved many lives.

2. Stickers

American physicist Spencer silver invented the glue but self-adhesive sheets for notes were created by Arthur fry. In 1968, silver was trying to create the perfect adhesive for working with paper that you can peel off the paper without tearing it. In addition, the adhesive had to be suitable for repeated use.

In the company where he worked silver, this idea nobody was interested. Until Arthur fry did not use glue to stick the bookmarks in the hymnal. He proposed to use a silver invented the glue for sticky reusable bookmarks. So the idea gained popularity.

3. Inkjet printer

Engineer at Canon accidentally put the hot soldering iron on the handle. And when the ink flowed, there was an idea to create an inkjet printer.

4. Dynamite

Discovered dynamite Alfred Nobel. He tried to make nitroglycerine more stable to prevent accidental explosions. A vial of the substance fell to the floor, where there was a lot of sawdust. Sawdust gave a small stability, and the bubble exploded. Nobel improved the formula by adding the nitroglycerin silica. And there was the dynamite.

5. Vaseline

English chemist Robert Chesbro in 1859 noticed that many oil industry workers complain of a waxy substance — "wax" which accumulate in the pipes of oil pumps. Chesbro immediately took a sample of the substance and began to experiment. It turned out, petroleum jelly perfectly heals wounds and cuts. The chemist gave him the name "vaseline" — (German. wasser — water and Greek. elaion — oil). The range of application of vaseline at the time was wide — from carpet cleaning to cleanse the nose. The author is so believed in the miraculous power of vaseline that all his life, ate a spoonful a day. He died in 96 years.

6. Viagra

Original purpose of viagra — the treatment of angina. But when producing pharmaceutical company Pfizer has studied the side effects, she found that high blood pressure does not fall, but the subjects appear excellent erection. So the company changed the kind of test and began to explore erectile dysfunction and the effects of viagra. In 1998, the office of quality supervision approved medication and since then many men have started a fun life

7. Stainless steel

English Metallurgist Harry Brearley was trying to create a stainless steel alloy for the production of weapons.

Stainless steel came when he mixed with 12.8 percent chromium and 0.24% carbon. The resulting alloy was stable even to acids of vinegar and lemon juice. Later the inventor realized that the resulting alloy is ideal for Cutlery, which were made of silver and carbon steel and gradually fell into disrepair due to corrosion.

8. LSD

Diethylamide of d-lysergic acid was opened by the Swiss scientist albert Hofmann, who tried to create a drug to ease pain during childbirth. The resulting material seemed to him unremarkable, and he shelved it. In 1943, while working without gloves, accidentally received a large dose of a substance he realized the true properties of the connection. He felt "a continuous stream of fantastic pictures, extraordinary shapes with intense kaleidoscopic play of colors".

9. Tea bag

Salesman 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 the buyers mistakenly omitted the full bags in boiling water, and the result they liked.

10. Microwave

In 1946, engineer Percy Spencer was testing a magnetron that emits microwave wave. During the tests the chocolate in his pocket melted. Percy suggested that this was due to the magnetron and placed near the instrument grain for popcorn. Receiving popcorn, Spencer decided to cook an egg, but it exploded. All this led him to the idea that low-frequency energy helps to quickly cook and a year later appeared the first microwave oven.
