Thomas Edison said - "Everything comes to the one who works and knows how to wait." But progress is not always the goal. Some brilliant ideas come to mind quite by accident. We present to you 10 inventions that were created completely by accident.
In 1942, the American physicist Dr. Harry Coover tried to separate the transparent plastic for the telescopic sights of portable weapons. During the experiment, he worked with cyanoacrylate, which glued the test materials tightly and tightly. But only 6 years later, Dr. Coover realized the full potential of this substance, which does not need either pressure or heat. This is how superglue was created.
An interesting fact - during the Vietnam War, superglue was used to stop bleeding in open wounds. This is how the invention that was supposed to improve the weapon saved many lives.
American physicist Spencer Silver invented glue, but self-adhesive note sheets were created by Arthur Fry. In 1968, Silver tried to create a glue for perfect paper handling that could hold the paper to the surface, but not strong so that the paper could be removed without tearing it. Plus, it had to be sticky for reusable use.
True, in the company where Silver worked, nobody was interested in the idea. Until Arthur Frye began to use glue to glue bookmarks in the psalter. It was he who suggested using the substance to create sticky reusable bookmarks. This is how the idea gained popularity.
3. Inkjet printer
A Canon engineer accidentally put a red-hot soldering iron on the handle. And when the ink started flowing, the idea arose for creating an inkjet printer.
Dynamite was discovered by Alfred Nobel. When he was working on nitroglycerin, he tried to make it more stable to avoid accidental explosions. The vial with the substance fell to the floor, where there was a lot of sawdust. The sawdust gave a slight stability and the bubble did not explode. Nobel improved the formula by adding silica to nitroglycerin. This is how dynamite came about.
The English chemist Robert Chesbrough noticed in 1859 that many workers in the oil industry were complaining about a wax substance - "paraffin", which accumulated in the pipes of oil pumps. Cesbro immediately took a sample of the substance and began to experiment. It turned out that oil jelly perfectly heals wounds and cuts. The chemist gave it the name "Vaseline" - (German "Wasser" - water and Greek "Elaion" - oil). The range of applications of petroleum jelly at that time was wide - from cleaning carpet to cleansing the nose. The author believed so much in the miraculous powers of Vaseline that all his life he ate a spoonful of it a day. He died at the age of 96.
The original purpose of Viagra is to treat angina pectoris. But when pharmaceutical company Pfizer looked at the side effects, they found that high blood pressure didn’t drop, and the subjects had excellent erections. So the company changed the type of testing and began to investigate erectile dysfunction and the effects of Viagra on it. In 1998, the quality control department approved the drug and since then, many men have had a fun life.
7. Stainless steel
English metallurgist Harry Brearley tried to create a stainless steel alloy for the manufacture of weapons.
Stainless steel came about when he mixed 12.8% chromium with 0.24% carbon. the resulting alloy was even resistant to the acids of vinegar and lemon juice. Later, the inventor realized that the resulting alloy was ideal for cutlery, which was made from silver and carbon steel and gradually deteriorated due to corrosion.
D-lysergic acid diethylamide was discovered by Swiss scientist Albert Hofmann, who was trying to create a drug that relieves pain during childbirth. The resulting substance seemed unremarkable to him and he put it on the shelf. In 1943, while working with a substance without gloves and accidentally receiving a large dose of the substance, he realized the true properties of the compound. He felt "a continuous stream of fantastic paintings, unusual shapes with an intense kaleidoscopic play of color."
9. Tea bag
Thomas Sullivan, a merchant in a New York store, decided that selling tea in silk bags would be much more convenient and sales of tea skyrocketed. It turned out that customers mistakenly dipped full bags into boiling water, and they liked the result.
In 1946, engineer Percy Spencer tested a magnetron that emits microwave radiation. During tests, the chocolate in his pocket melted. Percy assumed this was due to the magnetron and placed popcorn grains next to the appliance. After receiving the 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 food and a year later the first microwave appeared.
