10 inventions that have appeared by chance

Thomas Edison said - "Everything comes to those who are working and can not wait." But not always progress is the goal.Some great ideas come into my head by accident. You will find 10 inventions that were created by accident.

1. Superglue
In 1942, the American physicist Dr. Harry Coover was trying to separate the clear plastic for telescopic sights portable weapons. In the experiment, he worked with cyanoacrylate, which is very firmly glued test materials. 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 invention which was to improve the weapons saved many lives.

2. Stickers
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 perfect 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 for repeated use. 
truth in the company where he worked Silver anyone not interested in the idea. Until Arthur Fry did not use glue to adhere better to the hymnal. It was he who suggested the use of a substance for the creation of reusable adhesive tabs. So the idea has gained popularity.

3. Inkjet printer
Engineer at Canon accidentally put the hot soldering iron on the handle. And when the ink ran down the idea to create an ink jet printer.

4. Dynamite
Alfred Nobel discovered dynamite. When he was working on nitroglycerin, he tried to make it more stable to prevent accidental explosions. Vial of the substance fell to the floor, where it was a lot of sawdust. Sawdust is given a small vial stability and exploded. Nobel improved the formula by adding silica to nitroglycerin. And there was dynamite.

5. Petrolatum
English chemist Robert Chezbro in 1859 noticed that many oil-industry workers complain of a waxy substance - "wax", which accumulated in the pipes of oil pumps. Chezbro immediately took the test substance and began to experiment. Petroleum jelly turned out perfectly heals wounds and cuts. The chemist gave him the name "Vaseline" - (German »Wasser» - Water and Greek. «Elaion» - oil). The range of application of petroleum jelly at the time was wide - from carpet cleaning to cleanse the nose. The author is so believed in the magic power of Vaseline that all his life he ate a spoonful a day. He died at age 96.

6. Viagra
Viagra original purpose - the treatment of angina pectoris. But when produced by the 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 gender tests and began to investigate the effects of erectile dysfunction and it Viagra. In 1998, the Administration of Quality Supervision approved the drug, and since then many men have started gay life

7. Stainless steel
English metallurgist Harry Brearli tried to create a stainless steel alloy for the production of weapons. Stainless steel came 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 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 discovered by Swiss scientist Albert Hofmann, who was trying to create a drug eases pain during childbirth. The resulting material was thought he was not remarkable, and he put it back on the shelf. In 1943, while working with the material without gloves and accidentally received a large dose of a 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
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 the buyers mistakenly omitted the full bags in boiling water, and the result they like.

10. Microwave
In 1946, engineer Percy Spencer 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. Having 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 there was the first microwave.
