Everyone knows the horrors of war. But few know about its "positive" side. It turns out that most of the things that we use literally every day were invented precisely because of the war. Today the editors of our site will tell you about 7 such inventions.

Super glue

Superglue was invented quite by accident when the US military in the early 40s of the last century tried to invent telescopic sights made of plastic. In the course of the experiments, a strong-smelling liquid was obtained, which could tightly glue various objects to each other.

Internet

The predecessor of the World Wide Web was the 1969 operation by the United States Department of Defense to connect multiple computers to a single network. The military tried to simplify messaging in combat.

Plastic surgery

Plastic surgery would not have achieved such success if it were not for the ability of doctors to hone their skills on soldiers disfigured during the war.

Microwave

Thanks to World War II, radars were invented. In 1945, a scientist working on a radar array noticed that a chocolate bar in his pocket had melted. So the ability of microwaves to cook food was discovered.

Scotch

One day, President Franklin Roosevelt received a letter from a worker who complained that his sons had a hard time opening crates of grenades packed with awkward paper tape. The man offered his own solution to the problem - a two-layer tape on a fabric basis. This is how the well-known scotch tape was invented.

Chemotherapy

During the First World War, mustard gas was used, which caused distention in the lungs, as a result of which the victims literally choked. But despite this horror, studies have shown that due to such attacks, human blood lost the ability to produce blood cells. And later, scientists found out that the same thing happens with cancer cells.

Canned food

One of the greatest generals, Napoleon, was convinced that quality food is the key to an efficient army. But there was a huge problem of transporting food without spoiling it. After all, military campaigns could last from several months to several years. Then the enterprising military leader offered 12,000 francs to the one who would solve this problem. And one pastry chef suggested storing food in sealed containers. This is how the famous canned food was invented.
