Solution to the most common mysteries

It took 7 years to break down the gum

Although chewing gum can be proved to be more degradable than other organic foods, it does not have any special effects on the digestive system. Doctors say the new digestive seven-year story is just to prevent children from swallowing this sticky substance.

The Great Wall City is the only artificial structure visible from the universe

There are a few changes in this folk comment, and they are all wrong. Astronauts can recognize the low orbit of the Word, along with many other works such as the Giza pyramid and even the runway. But they could not see the Castle from the moon.

People use only 10% of the brain

This information has appeared for at least a century. But fortunately, it's not true at all. The MRI picture clearly shows - people put most of the cortex into a useful active state, even when taking a nap.

Water flows backwards in the Southern hemisphere due to the rotation of the earth

Not only is the earth's rotation too weak to affect the flow of water in a duct, the tests that you can easily do yourself in the washbasin will show the whirlpool in both directions depends. into the tank structure, not the hemisphere.

Hair and nails continue to grow after death

Although our hair and nails still seem to be long after death, this is simply an optical illusion. The body of the dead person is severely dehydrated, pulling the skin, making the nails and hair more exposed.

The coin falling from the top of the building can kill pedestrians

A coin is not the greatest kinetic weapon. The combination of the shape and resistance of the wind meant that, if released from a height of 380 meters of the Empire State Building, it would fly fast enough to sting an unlucky pedestrian.

There is no gravity in the universe

The concept of "zero gravity" is the culprit for this misunderstanding. Gravity is everywhere, even in the universe. Astronauts seem to be relieved because they are in a state of continuous freefall on the earth, and hovering because of horizontal movements. The influence of gravity gradually decreases as the distance increases, but never really disappears. Also, it's not right to say that the universe is vacuum. There are many kinds of atoms there, although they are sometimes far apart (and this thin gas also contributes to the fascinating storage).

Headless chickens still live

Yes, and not just for a few minutes. A chicken can stagger after being beheaded, because the brain stem - the part that is left a little after being cut - controls most of its reflexes. Such an animal lived healthy for 18 months.

Rule of 5 seconds

Think about the cake falling to the floor after 5 seconds to get in contact with the bacteria, enough time to pick it up and put it in your mouth. Unfortunately, tests (and logic) determine that bacteria can cling to most foods almost immediately.

Falling cats always touch their feet to the ground

Studies have shown that, when dropped from most height, cats can land safely on their feet. But this changes when it falls back from a height of less than 0.3 meters or more. Also recommend that you do not try this at home.

Adults do not grow new brain cells

Most important areas of human brain thrive during adolescence, but it does not descend there. Studies have shown that neurons continue to grow and change rapidly in adult years.
