Appearance of matches

In one English city lived a very educated pharmacist John Walker, who was fond of science. He prepared medicines for various diseases for his clients. For hunting shells, Walker created a material by combining different substances, which he stirred with a stick in a glass.

After the stick with the mixture dried on it dried out, John wanted to clean it by rubbing the stick on the floor. But she ignited! So, on April 7, 1827, the first matches were created. After a while, John sold his first box of matches, and noted this event in his book. Hickson became its first buyer, more than 180 years ago. And in honor of Walker, a street was named in his hometown of Stockton.

First lighter

We know that today, flint for lighters is composed of magnesium, iron, copper, cerium and lanthanum, not silicon. And the first table lighter was invented by the German chemist Johann Wolfgang Dobereiner in the early 19th century.

When creating a lighter, he used finely crushed platinum and its catalytic properties. The fuel of the lighter has become hydrogen, which has the ability to explode powerfully. This became the most vulnerable point in the invention.

Monopoly Game

The best-selling game in America was Monopoly in 1935. To date, it has sold over 250 million copies. The inventor of "Monopoly" is Charles Darrow, who created it during the Great Depression in 1934. He first showed his project to Parker Brothers, but they rejected it, citing design errors, of which there were 52 pieces. Then Charles decided to release this project on his own, and sold 5000 copies of the game, after which he again turned to the representatives of the company.

Pressure force of the chewing muscles

The usual pressure of a person's jaws is 9-15 kilograms. When you, for example, gnaw nuts, the pressure reaches up to 100 kilograms. It has been shown that the absolute strength of the chewing muscles on one side is 195 kilograms, and on both sides it can reach 390 kilograms. But, under normal conditions, this force is not used, since the periodontium cannot withstand it.

Candy wrapper

The first wrapper for sweets was waxed paper, which was created by the great scientist-inventor Thomas Alve Edison in 1872. In total, his "arsenal" contains about a thousand patents, including a typewriter, a direct current generator, an exchange telegraph, a phonograph, and, naturally, a light bulb. Although he only improved the light bulb, it was the Russian scientist Alexander Lodygin who invented and patented it for the first time. In 1882, according to the project of Thomas Edison, the first DC power plant was built.

Champagne cork speed

It is believed that the origin of the thick glass bottle, as well as the technology for making sparkling wine, is France. But, in Britain, claims appeared that it was in England that they appeared several decades earlier. Friedrich Balk, a German physicist at the Technical University of Clausthall in Lower Saxony, came to the conclusion that the speed that a cork escaped from a bottle of champagne reaches is 40 km / h. He measured it with acoustic and photovoltaic devices.

To achieve this, the bottle only needs to be shaken to create a pressure of 2.5 bar inside it. When a bottle of champagne is in direct sunlight for some time, then, with good shaking, a pressure of 3 bars will arise in it, and then the cork from the bottle will fly at a speed of 100 km / h!

Coat hanger

What people used to hang their clothes on is not clear. After all, a patent for a coat hook was obtained only in 1869, O.A. North. At the wire factory where Albert Parkhouse worked, there were constant complaints from workers that they did not have enough hooks for their coats. Then, in 1903, he built two ovals of wire, which were located at a certain distance, parallel to each other. Their ends were hooked.

Later, in 1932, in order to avoid sagging wet clothes, as well as to prevent wrinkling, the ovals were connected with cardboard. Three years later, the invented hanger with a bottom bar became the prototype for all modern hangers.

Toilet paper

In ancient times, after satisfying their natural needs, the Vikings wiped themselves with hairballs. The Americans used all kinds of leaves and ears of corn for these purposes. In ancient Rome, this hygienic procedure was performed using a sponge attached to a stick. Then she was placed in a solution with salt water.

François Rabelais argued that it is most pleasant to do this procedure with the help of a live duckling. The French kings approached this issue very exquisitely - they used linen rags or lace. The very first to use paper were the Chinese emperors. Much later, paper was used by everyone else in the world. For these purposes, catalogs, old newspapers and almanacs were used.

Cutting paper into squares and packing it into packs first occurred to New Yorker Joseph Gayeti, in 1857. On each piece of paper, he printed his name, because he was very proud of his invention. The name of the person who first wrapped the paper on a roll is not known. But in 1890, the American paper mill "Scott Paper" was the first to produce such rolls.

Button

Who invented the very first button is not known. Some believe that it was the Romans or the Greeks, others think that the button is from Asia. Most often, buttons were created from ivory. Ancient people used thorns from plants, sticks or bones of animals instead of buttons. The Egyptians passed one piece of clothing through a hole that was made in another piece. They also used buckles, or simply tied the ends of the clothes.

The recognition and widespread use of buttons only reached in the 18th century, and were a sign of noble birth and wealth. Silver and gold buttons were ordered by the kings of the aristocracy. Buttons made of copper or metal began to be made only at the beginning of the 18th century. But they were so expensive that they were used many times, changing from one garment to another.
