Also, when you open your drink, the gasses go\u00a0out in\u00a0the form of\u00a0bubbles. And the drink is\u00a0likely to\u00a0overflow. The gap helps with this problem too. (Except if\u00a0you shake it\u00a0up\u00a0first, then open\u00a0it. No, I\u2019ve never done that.)\n\n

There are sounds most people can\u2019t stand, like the sound of a fingernail on a blackboard or someone scratching a window. Such noise irritates the amygdala. That\u2019s a small part of your brain controlling your emotions \u2014 including fear and survival instincts.\n

Some cheeses have holes in them. They\u2019re called \u201ceyes.\u201d These \u201ceyes\u201d are made by bacteria used in the process of production. When cheese is almost ready, these bacteria release carbon dioxide. And this gas forms bubbles that later become the cheese\u2019s \u201ceyes.\u201d See?\n

Cats knock different things over because of their hunting instincts. Your cat is simply checking whether the thing is alive or not. Or it might want your attention. Cats are smart and know that humans come very fast when something is broken.\n

When the pizza dough is ready, it gets manually spun in the air. This process removes lumps and creates its circular shape. It\u2019s more convenient to bake a round pizza \u2014 this way, it gets heated evenly. Plus, it\u2019s easier to cut a round pizza into equal parts.\n\"\"\n\n

\n

There have been reports of raining frogs, fish, and other unusual stuff dating back to ancient civilizations. Strong winds, such as those in a tornado or hurricane, sometimes get so powerful that they can lift up a school of fish or frogs and \u201crain\u201d them somewhere miles away.\n

Lightning is never a triangle, straight line, or circle. It always has a zigzag shape. Lightning is an electric current, and it always takes the path of least resistance. Air is uneven and irregular, containing dust particles, gases, and other substances. Lightning just seeks the best way through.\n

Flowers have different colors because of the color pigments they contain. But there are other factors, for example, the amount of light they receive while growing. Or the temperature of the environment around them. Even the pH level of the soil can have an impact on flowers\u2019 coloration.\n

By tilting their head, dogs try to understand all you\u2019re saying correctly. It\u2019s the way to adjust their ears to the sounds they hear. It may also be a way to show their empathy to the owner. Or they got something stuck in there.\n\"\"\n

Tickling is\u00a0bound to\u00a0cause a\u00a0laughter reflex. But nothing will happen if\u00a0you tickle yourself. That\u2019s because there will be\u00a0no\u00a0element of\u00a0surprise\u00a0\u2014 your brain knows what you\u2019re going to\u00a0do.\n

Barcodes speed up\u00a0the purchasing process. If\u00a0a\u00a0barcode consists of\u00a012\u00a0digits, the one on\u00a0the very left is\u00a0a\u00a0system identifier. For example, two means it\u2019s a\u00a0randomly weighed item. Three is\u00a0used for products related to\u00a0health. The next five digits identify the manufacturer. And the following five are the product\u2019s numbers. The last one is\u00a0\u201cthe check digit.\u201d Scanners need it\u00a0to\u00a0make sure they\u2019ve read the code correctly.\n

The song is\u00a0bound to\u00a0get stuck in\u00a0your head if\u00a0its music is\u00a0simple, the text is\u00a0repetitive and short, and the rhythm makes you move. Another reason you might have an\u00a0earworm is\u00a0that you hear some songs too often. And your brain can easily detect them.\n

Highlighters are filled with a\u00a0special semi-transparent fluorescent ink that can glow in\u00a0dim light. Yellow and light-green hues are the most popular because they don\u2019t prevent you from seeing the text after black-and-white photocopying. Photocopiers perceive yellow and light-green marks as\u00a0very pale and don\u2019t print them.\n\n

With age, your hair loses its natural color. It happens because keratin receives less pigment. As people grow older, the pigment cells in their hair follicles gradually vanish. And hair becomes gray. Some time passes, and no pigment is produced at all. That\u2019s when hair turns white.\n

Trees stop growing at a certain age. It might be because when a tree reaches a particular height, it gets difficult for it to pull water from the soil. Because after that, it needs to pump it all the way up to the top \u2014 and that\u2019s when gravity comes into play. Some trees, like the baobab, start growing out instead of up once they reach their full height.\n

Your own body makes mosquito bites swell and itch! A mosquito breaks your skin. Your immune system perceives the insect\u2019s saliva as a foreign substance. So it starts a special reaction to flush the intruder out of your body. A compound produced by the immune system, called histamine, makes the blood flow faster around the bitten area. And it causes swelling. The histamine also sends a signal to the nearest nerves, which makes the bite itch.\n

Geese usually fly in a V-shaped formation to conserve energy and make sure none of their team members gets lost.\n

You can\u2019t hum while holding your nose. Trust me. During humming, you exhale air. But when both your mouth and your nose are closed, the air can\u2019t escape. The longest you can hum like this is two seconds. Then you\u2019ll have to open your mouth and catch your breath.\n

Road and construction workers are usually dressed in orange because the bright orange hue is visible even in bad weather. It\u2019s the most effective color to attract attention and alert people. No wonder lots of safety jackets and traffic cones are orange as well.\n

Modern-day perfectly round coins used to be shaped randomly or had no shape whatsoever in the past. But dishonest people stole valuable metals the coins were made of by chipping their corners off. Of course, it was illegal. To prevent this kind of fraud, they invented round coins. After that, it instantly became obvious when coins had been fiddled with.\n

Most ambulances have this word printed on the front of the vehicle \u2014 which is the word \u201cambulance\u201d backward! It\u2019s written in reverse so that the driver in front of the ambulance can see the word properly in their rearview mirror. Then they can move out of the way and let the ambulance pass.\n

White is the most popular color for painting aircraft. It reflects sunlight most effectively, which doesn\u2019t let the plane heat up too much. All kinds of cracks, dents, and other damage are much more visible on the white background. It means the fault can be spotted and repaired as fast as possible. And finally, it costs less to buy white-colored airplanes because it\u2019s the color they have \u201cat birth.\u201d\n

Unlike what many people believe, adding salt to water won\u2019t make it boil faster. It\u2019s true that saltwater gets hotter more quickly than the regular one. But its boiling point is also higher since salt adds some extra mass to the water. So it won\u2019t make things speed up.\n

The first basketballs were brown because they were made of brownish leather. But such balls were difficult to see both for players and for fans. To make the basketball more visible, they decided to make it orange. Ooh, like the traffic cones…\n

Flamingos are born gray. But they turn pink because of their diet: a lot of tiny shrimps and blue algae. Both of these products are packed with special pigments. When the flamingo\u2019s liver processes these pigments, special molecules travel to the bird\u2019s legs, bill, and feathers, painting them pink.\n\"\"\n\n

Donuts are shaped like rings because, otherwise, they might get overdone at the edges but uncooked and gooey inside. With a hole in the center, both the outsides and the insides get ready at the same time.\n

Bears don\u2019t sleep for months during hibernation. Instead, all the processes in their bodies slow down. They don\u2019t need to eat or drink. But they can still react to any unexpected things going on around them.\n

You see the Sun as yellow or orange because the atmosphere of our planet scatters such colors as blue, green, and violet. This is also why the Sun looks warmer at sunrise and sunset.\n

Emergency services use two colors of flashing lights, red and blue. The red one is associated with warning and danger. It\u2019s also one of the most noticeable colors. But this color can get lost in heavy traffic because most cars have red tail lights. That\u2019s when blue flashing lights come in handy.\n\"\"\n\n

Your tongue doesn\u2019t have separate bitter, sweet, sour, or\u00a0salty sections for tasting. Each of\u00a0the 8,000 taste buds you have on\u00a0the tongue, the roof of\u00a0the mouth, and even in\u00a0the throat can detect all the tastes.\n

Lots of\u00a0private houses have triangular-shaped roofs because this allows rain, snow, and fallen leaves to\u00a0slide off the slope. If\u00a0all this stuff piled up\u00a0on\u00a0top of\u00a0your house, one day, your roof would collapse.\n

Kangaroos have muscular legs, big feet, and tails that allow them to\u00a0move forward really fast. But the animals can\u2019t go\u00a0in\u00a0the opposite direction. That\u2019s because of\u00a0their body construction.\n

Leather often looks dull to\u00a0the eye because it\u2019s covered with itsy-bitsy scratches and scrapes. They scatter the light that hits the material. When you coat your shoes in\u00a0a\u00a0layer of\u00a0wax, you fill these tiny crevices. The surface becomes smoother, and the rays of\u00a0light bounce off it\u00a0more evenly. That\u2019s why the leather looks shiny.\n\n

Bread tag colors indicate the day when the bread was baked. For Monday, they use the blue tag. Tuesday is\u00a0green, and Thursday is\u00a0red. Bread bags have white tags on\u00a0Friday, and on\u00a0Saturday, they are yellow. This makes it\u00a0easier for grocery store employees to\u00a0remove stale bread from the shelves and replace it\u00a0with freshly baked ones.\n

Wimbledon tennis balls are always stored at\u00a068\u02daF. The temperature can influence their bounciness. When the ball is\u00a0warm, gas molecules inside it\u00a0expand. This makes the ball bouncier. After the ball cools down, the molecules shrink. This decreases the bounciness.\n

When a\u00a0storm is\u00a0coming, clouds seem to\u00a0turn dark. But it\u2019s just an\u00a0illusion. Thin clouds on\u00a0a\u00a0sunny day let the light through easily. They also scatter all the colors of\u00a0the light spectrum. This makes\u00a0us perceive the clouds as\u00a0white. But the thicker the clouds are and the more water droplets they contain, the less light they let through and the darker they look.\n

Modern light bulbs come in\u00a0all shapes, styles, and sizes. But in\u00a0the past, all light bulbs used to\u00a0be\u00a0spherical. This shape made the glass stronger and less prone to\u00a0breaking. And the sphere worked best when it\u00a0came to\u00a0delivering light evenly.\n\n

If\u00a0your blender stops chopping food and just spins it\u00a0around in\u00a0circles, you\u2019ve probably skipped the \u201cpulse\u201d button. Most modes make the ingredients move around in\u00a0the same direction at\u00a0the same speed. But the pulse function creates turbulence. And instead of\u00a0rolling around, fruit pieces fall into the center and turn into a\u00a0smoothie. I\u00a0like smoothies.\n

The markings on\u00a0the bottom of\u00a0a\u00a0toothpaste tube are there for the factory robots. Colorful squares mark the line that helps the machines understand where to\u00a0cut and fold the tube.\n

Green and black tea come from the same bush. The leaves get their different tastes and look after they get harvested. Green tea is\u00a0withered and heated through steaming. And black tea is\u00a0crushed or\u00a0curled and then left to\u00a0oxidize and darken.\n

The stop sign has an\u00a0eight-sided shape to\u00a0help drivers recognize it\u00a0easily\u00a0\u2014 even if\u00a0they see it\u00a0from the back. And when the signs weren\u2019t reflective yet, the octagonal shape prevented drivers from confusing the stop sign with any other at\u00a0night.\n\n

Water is\u00a0great at\u00a0cleaning stuff because it\u00a0has triangular molecules. They\u2019re made of\u00a0one oxygen and two hydrogen atoms. Um,\u00a0H2O? Such molecules have slightly different charges on\u00a0their opposite sides\u00a0\u2014 pretty much like magnets. That\u2019s why water easily sticks to\u00a0other molecules, including those that makeup dirt!\n

Glass breaks so\u00a0easily because its atoms are arranged rather loosely and randomly. They can\u2019t rearrange themselves fast enough to\u00a0maintain the glass\u2019 structure. As\u00a0a\u00a0result, glass doesn\u2019t bend; it\u00a0shatters.\n

Earth doesn\u2019t get closer to\u00a0the Sun in\u00a0the summer. In\u00a0reality, it\u2019s closest to\u00a0it\u00a0in\u00a0January and farthest in\u00a0July. It\u2019s warmer in\u00a0the summer because Earth\u2019s axis is\u00a0tilted. It\u00a0lets the planet\u2019s northern part catch more sunlight for half of\u00a0the year and the southern part\u00a0\u2014 for the other half.\n

You can always squeeze in\u00a0some dessert, no\u00a0matter how much salad, soup, or\u00a0meat you\u2019ve eaten before. Your body gets bored of\u00a0savory tastes. But when you see and smell something sweet, like ice cream, cakes, or\u00a0chocolate, your brain gets excited. It\u00a0overrides all fullness signals for pleasure. Plus, your stomach is\u00a0a\u00a0flexible organ, and sugar helps it\u00a0relax and physically make room for dessert. I\u00a0can use that information.\n\n

The first solar calculator hit the shelves in\u00a0the late 1970s. That\u2019s when scientists began experimenting with relatively cheap solar cells. Calculators were among the first products that needed little power to\u00a0work. Later, this technology moved to\u00a0larger stuff, such as\u00a0lights and highway signs.\n

Light isn\u2019t the fastest thing in\u00a0the world. Of\u00a0course, nothing can compare to\u00a0its speed in\u00a0a\u00a0vacuum. But it\u00a0slows down while going through water or\u00a0glass.\n

Oranges (the fruit, not the traffic cone) aren\u2019t always orange. The green-skinned variety is\u00a0just as\u00a0sweet and ripe. This unusual skin color protects oranges from the Sun. It\u2019s also a\u00a0sign there\u2019s plenty of\u00a0chlorophyll in\u00a0the fruit. That\u2019s why green oranges mostly grow in\u00a0warmer climates.\n

A\u00a0shadow is\u00a0cast when you have an\u00a0object in\u00a0the path of\u00a0light. Light travels in\u00a0a\u00a0straight line, which is\u00a0why you always get a\u00a0shadow when something\u2019s in\u00a0front of\u00a0a\u00a0light source. Birds and airplanes are no\u00a0exception. They DO\u00a0cast shadows, but you can\u2019t see them. The closer the object is\u00a0to\u00a0a\u00a0source of\u00a0light, the denser its shadow\u00a0is. And if\u00a0the object is\u00a0too far away, its shadow disperses.\n\n\n\n\n\n\n\n\n\n\n\n\n","protected":false},"excerpt":{"rendered":"
