WHY is filtered beer not the same as unfiltered beer?
Unfiltered beer differs from conventional beer as it is not pasteurized. For this reason, unfiltered beer retains more nutrients, but has a shorter shelf life.
Also, as the name suggests, unfiltered beer undergoes fewer filtration steps - it retains yeast residue and remains cloudy.

WHY does the wood in the fire crackle?
In simple terms, the combustion process consists of two stages: pyrolysis of wood and combustion of its products. Pyrolysis is the decomposition of complex organics at temperatures up to 450°C. Approximately one quarter of the products are released immediately in the form of gases: carbon dioxide, hydrogen, methane and carbon monoxide. Another half of the wood mass combusts to form a liquid consisting of water and various organics.
The rest of the mass forms charcoal, which is 80-90% carbon. It is highly porous and smolders by interacting with the oxygen that enters its pores. The resulting gases accumulate between the layers of wood and tear them apart with a loud crackling sound.
The wood also crackles constantly, as it shrinks from the heat and deforms, causing the brittle charcoal that formed on the logs during pyrolysis to collapse.

WHY do moths eat clothes?
Perhaps, you may be surprised that those flying moths you chase all over the house with a newspaper in your hands simply can't eat.
Yep, yes, an adult moth has absolutely no appetite because of the absence of mouthparts, but its larvae have an excellent appetite, which hatch from the eggs laid in the clothes.
As soon as the larvae are born, they need nutrients of natural origin, such as protein, which is found in abundance in clothing made of natural raw materials. The hungry caterpillars pounce on fabrics of animal origin and eat lint after lint, leaving holes in them in the end.
Well, at least you can rejoice that your pestered clothes are actually made of natural wool.

WHY did Picasso stoke the stove with his paintings?
In 1900, Picasso moves from Spain to Paris, where he spends time learning about the work of the Impressionists. His life during this period was fraught with many difficulties. The artist was so poor that at times he was forced to heat the stove with his own paintings instead of firewood. The prospect of freezing from the cold seems to have been much worse for the artist than the sacrifice of his art.
However, the sacrifice was not in vain, because it is thanks to the difficult circumstances of life in the works of the painter there is a famous "blue period. The palette of these paintings are characterized by blue shades. In the paintings of this period are clearly represented the images of poverty, sadness and melancholy, the themes of old age and death.
The artist depicted the poor, the blind, alcoholics and prostitutes, trying to show the world human suffering

WHY shouldn't we drink yesterday's tea?
If the drink is left outdoors for several hours, bacteria and harmful compounds begin to form when exposed to oxygen.
On the surface of the tea, they look like a thick dark film, which leaves a stain on the mug.
By the way, the most destructive effect of these substances is on the organs of the gastrointestinal tract, mainly the liver.

WHY doesn't food burn on oil?
Oil prevents overheating. Food does not conduct heat well. When frying in a "bare" pan, the bottom layer of the food gets so hot that it can char, while the top of the piece stays raw. The oil transfers the heat from the lower layers to the upper ones.
The main thing is that it, like any liquid, cannot get warmer than its boiling point since the incoming new heat is carried away with the vapor. The boiling temperature of oil is sufficient to form a crispy crust on food.
Cooking and braising do not produce crusts: in these cases, water, which has a relatively low boiling point, plays the role of a stabilizer.

WHY does each flower have a different scent?
To attract the right insects.
Almost all fragrant flowers are pollinated by insects. Plants benefit from pollinators visiting one flower and flying to another one.
Then the flowers will get pollen of their own kind, not someone else's. To this end, flowers have features that help insects recognize them: shape, coloration, and, of course, smell. It can include substances that are attractive to the "right" pollinators.

WHY can't you pull the pin out of a grenade with your teeth, like in the movies?
The fact is that the grenade is a dangerous weapon that has a large kill radius when it explodes. To prevent it from going off accidentally, the pin mechanism is made very tight. You can't just pull it out like that.
Even if you can do it with your teeth, the "hero" will then eat only porridge and ground fruit - he will not be able to chew.

WHY are there freshwater icebergs in the salty ocean?
Since the glaciers of Greenland and Antarctica.
When the salty ocean water evaporates, it turns fresh and falls as precipitation. In Greenland and Antarctica, the fallen snow compacts under its own weight and slides off the edges of the land. A so-called ice shelf glacier is formed, and huge pieces of icebergs break away from the edges of the glacier.

WHY did the church conclude that the fork was a tool of the devil?
At one point, Christian theologians in Europe declared that the fork was "Satan's fork".
Perhaps it was the medieval denial of all things ancient. Since the culture of ancient Greece was based on belief in multiple gods, Christian preachers saw the cutlery as a mini-trident of Poseidon, god of the sea.
For centuries, the Catholic Church did not allow the use of a fork. When the French queen Jeanne d'Herve, who treasured her only fork, died of the plague in the fourteenth century, churchmen called her demise payback for her reckless fondness for the devil's object.
Only by the 16th century did the fork overcome Catholic prejudice. And in 1630 Governor Winthrop of Massachusetts had the first and only fork in colonial America.

WHY is Chanel No. 5 perfume called that?
According to legend, Madame Coco asked Mr. Beaux to create a scent "that would smell like a real woman". Beau was originally from Russia and worked as a perfumer at the tsar's palace, but he had to flee the country after the revolution.
He was experimenting with aldehydes (synthetic floral scents) when Chanel asked him to create a never-before-seen fragrance. As a result, Mademoiselle Coco was faced with ten perfumes. She decided on the fifth one, after which she decided to call it by that simple and memorable number.

Why do cats' eyes glow?
The inner surface of these animals' eyes has a shiny layer, the so-called mirror, which reflects light. The eyes of these nocturnal predators do not produce light as they only reflect the faint light emitted by stars, the Moon, distant light sources that penetrate into the eye and focus on its back surface.

WHY does the voice change with helium?
When you inhale ambient air, your vocal cords vibrate in "normal" mode.
However, helium has a lower density, around 7 times lower than air. As a result, the vocal cords are less strained and vibrate at a higher frequency. The voice becomes higher and more squeaky.
And if you inhale a heavy gas, such as sulfur fluoride, which is five times heavier than air, even a 7-year-old girl will start to speak in a bass.

WHY are the lights dimmed during airplane takeoff?
The reason for this is to get the passengers' eyes used to the darkness, not for comfort but for safety reasons.
If the passengers have to be evacuated immediately, their eyes will be better prepared for the darkness outside 🛫

WHY is blood taken from the ring finger?
The fingertips are easily accessible, hairless, rich in blood vessels, easy to disinfect, and even squeeze if necessary. The skin on the ring finger is thinner than on the thumb, index and middle finger, and contains fewer nerve endings, including pain receptors.
The little finger, on the other hand, is closely connected to the wrist, so if an infection is introduced into a wound on the little finger, it can spread to the bend of the wrist!

WHY do some people only smoke when they're drunk?
Well, there have been various studies on this subject in America. One of them, carried out at a medical center, found that alcohol increases the pleasurable sensation of smoking.
According to another one, performed at a medical university, it was found out that nicotine allows you to drink more alcohol without feeling sleepy.🚬

WHY do we see twinkling stars?
It happens due to the fact that their light, as it flows through the atmosphere, passes through layers with different densities. The refraction is varied, with the layers of air constantly moving in relation to each other.
When the starlight moves from a lower-density layer to a higher-density one, it begins to flicker.✨

WHY is the smell of thunderstorms dangerous?
Have you ever smelled a specific thunderstorm? That's the smell of ozone, an allotropic modification of oxygen. The gas forms as a result of electrical discharges.
Ozone (O₃) is an active substance and an aggressive oxidizing agent. Breathing air with a high concentration of ozone causes respiratory disorders. We can conclude that breathing the smell of thunder is harmful.
Yet, there is the other side of the coin. The ozone layer of the atmosphere protects Earth from cosmic rays.

WHY does white piece go first in chess?
No, racism has nothing to do with it...
Until now, there is no exact answer as to why whites move first. The first mention of the chess game is dated back to 2.5 thousand years ago, the rules of the game gradually evolved over time.
At first the game was called "Chaturanga" and played by 4 people at the same time. The pieces were black, green, yellow and red.
With the passage of time, the number of participants was reduced to two, and the figures were black and yellow. Yellow was soon replaced by white.
Black is thought to be the color of sadness, the color of what is going away. White is the color of life, the color of what is just beginning.

WHY doesn't ice sink?
The only water crystal modification existing under the conditions of our planet is the hexagonal syngony.
❗This chemical structure has a lower density than water as a liquid.
It only occurs under natural conditions. Scientists have already found out that ice has 5 amorphous varieties and 17 crystalline modifications.

WHY do the Germans read numbers backwards?
By the end of the 15th century, Arabic numerals became common in written German. They were recommended to be read from left to right. But when numbers didn't exist, the Germans always wrote units first (one dash for 1, two dashes for 2) and only then - tens (X - 10).
As an example, the notation IXX used to read "one and twenty".
The Germans still have such a peculiarity. Previously, writers and mathematicians were constantly pointing out the problem of the distorted transmission of numbers. But all their attempts to do anything about it were suppressed from above.
