WHY is the center of the universe is in Tulsa?
Tulsa is a small city in Oklahoma, a unique acoustic place. "The Center of the Universe" is a 75 cm diameter circle of concrete. It is followed by the next circle of 13 bricks and circular brickwork. The whole area extends to about 2.5 m in diameter.
If you stand in the center of this place, any sound you make will be amplified many times over, and the person standing outside the circle will hear your voice distorted and indistinct.

WHY are tsunamis occurring?
When large underwater earthquakes shake the seafloor, tsunamis appear. And the stronger the shocks, the more powerful the tsunami will be.
Underwater landslides and explosions also cause tsunamis. So-called megatsunamis are caused by above-water landslides or "glacier calving".
📌 Unfortunately, tsunamis, as well as earthquakes, are still impossible to predict accurately.

WHY shouldn't we take a starfish out of the water?
Starfish pump in and out of water through their body surface. This way it breathes.
If you take a starfish out of the water, it will get air into its body, but once submerged, it won't be able to sink to the bottom and breathe normally. As a result, it will die an agonizing death.
❗You cannot pull a starfish out of the water for more than 3-5 seconds.

WHY do you see colored circles while rubbing your eyes?
You may have noticed that every time you rub your eyes, the colored flashes are always of a different shape and color😏
Pressing on the eyeball causes mechanical irritation to the retina and optic nerve.
This signal goes to the visual centers of the brain, which perceive it as a normal signal from the retinal receptors.

WHY is chewing gum hard to digest?
That's why chewing gum labels say you cannot swallow it.
The gum is made of plastic, the gastric acid and enzymes are unable to digest it and it passes through the digestive tract unchanged.
❗Only the plant substances such as additives and flavors are digested. The base material is eliminated from the body naturally.

WHY does watermelon not sink in water?
Cause it looks like a ball, and it doesn't sink! Yet watermelon is many times heavier than a ball, and it would seem that it should sink.
The answer to this question lies not in the form, but in the content.
Thing is, the striped berry is mainly composed of water. However, due to the fact that its flesh is porous, its density is less than that of water. For this reason, the berry does not sink, but floats on the surface of the liquid.

WHY do muscles increase in volume after working out?
During a muscle workout, the muscle fibers are torn and the outer cell membranes are destroyed, causing the release of signaling substances.
After that, muscle tissues actively divide and their number, size increases. The muscle becomes bulkier💪🏼

WHY are the pills made in different colors?
The pills, in addition to their direct effect, impact the patient psychologically.
Scientists have proven that the psychological effect is stronger for pills with "beautiful" colors.
📌 Besides, the coloring helps to distinguish the pills. Of course, all dyes have to be tested for safety.

WHY do restaurants give mint gum to customers?
The staff is not trying to hint at customers' stale breath in this way, as it may seem at first 😄
The idea is to take care of digestion. Peppermint soothes the smooth muscles of the gastrointestinal tract. Products containing mint can eliminate heartburn, feelings of bloating and overeating.
The restaurant is interested in making you feel great after your meal.

WHY are the auroras multicolored?
During collisions, atmospheric atoms can lose electrons (ionize) or turn into an excited state for a short time. Photons with different wavelengths are emitted, which is what the human eye or camera sees.
Oxygen is responsible for the green or brownish-red color, as well as the greenish-yellow polar lights. Other constituents of the atmosphere also make small contributions, such as hydrogen and helium giving blue and purple colors.

WHY does audibility improve after it rains?
During and after rain, sound travels best due to little dust and other particles in the atmosphere that absorb and weaken sound waves.
Yet, during fog, when the atmosphere is full with water, audibility gets worse.

WHY do we put out fire with water?
Water, sand, foam, and anything else that puts out a fire cuts off the oxygen to it.
The substances thus cover the burning area and stop the chemical process. Besides, water has a high heat capacity and heat of evaporation. It cools the burning material and slows down the release of combustible gases.

WHY is the temperature on the thermometer set at 42° C?
Have you ever boiled an egg? After a few minutes of boiling, the protein curdles, becomes dense and white; this process is called denaturation.
📌 At 42°C, the body also starts denaturing (clotting) blood proteins.
Furthermore, at this temperature, metabolic disorders begin in the brain. Such a condition is already incompatible with life, i.e. fatal.

WHY don't birds fall when sleeping on a branch?
Humans can fall asleep when their muscles are as relaxed as possible. In birds, it's the other way around.
❗For them, sleep is only possible when they tense the leg muscles that help them sit steadily on the branch.
These muscles are connected to the fingers by long tendons. When a bird sits down, the muscles contract, the tendons tighten, and the fingers clench. During sleep, the bird cannot straighten its legs, so the toes do not release their support.

WHY do sharks never sleep?
Some species have to swim all the time, otherwise water stops flowing through their gills so they cannot breathe.
Others rest during special periods, but do not fall into an unconscious state.
❗Normally, a shark can rest, remaining in place, for no more than an hour. If it fell asleep for a long time, it would die from lack of oxygen.

WHY do llamas spit at people?
📌 According to Successful Farming research, these animals can spit up to 3 meters long😱
They do this most often in a group to establish hierarchy or to tell an unwanted guest to leave.
If a llama spits at a person in the zoo, it means that he annoys it or intrudes on its territory.
So it is better not to stand next to this cute creature at the zoo😌

WHY don't your eyes freeze in winter?
Our body has a unique thermoregulatory system. When the ambient temperature drops, the blood flow to the eyeballs increases, bringing them additional heat, which prevents them from turning into ice❄
The fluid that moisturizes the eyes contains salts. The salt water keeps your eyes from freezing even in extremely cold temperatures.

WHY does food seem disgusting after brushing teeth?
Sodium lauryl sulfate is a foaming agent that is added to almost all toothpaste. It weakens the taste buds responsible for perceiving sweet flavors.
The foaming agent also destroys phospholipids, which normally reduce the sensation of bitterness.

WHY is it easier to swim in salt water than in fresh one?
❗Salt is what makes water heavier. And the greater the density (weight) of water, the easier it is to float in.
An object can float in a liquid if its weight is equal to the weight of the water it pushes out (the water is displaced to give room to the object).
You can also look at it from another angle: if you sit in a tub of water, the water level in it rises. If you drain the water that your body has displaced, the weight of it will be equal to the weight of your body.
