  • Hey it's time to shape up! Think about it! You pay with round coins for a round doughnut

  • with a hole, pass the octagonal stop sign on the road, step into the house, turn on

  • the round light bulb, then the rectangular TV and ask yourself: why do objects have such

  • shapes? Well, I'm going to tell you.

  • The bulb is round because the light is distributed evenly this way. The tungsten thread (which

  • is lit) should be in the center. And in the round shape it's easiest to mark the center.

  • Besides, these light bulbs are cheaper and easier to produce.

  • Toilet paper is roll-shaped because machines making those rolls process them much faster

  • than individual leafs. Earlier on, toilet paper was sold in square sheets, but such

  • production required more energy and time. Donuts have a hole in the center so that the

  • dough is evenly fried. There's even a story that a Captain Gregory, then a 16-year-old

  • sailor, made a hole in a lump of dough, which was then fried to create the world's first

  • doughnut. And no, he was not a cop! Initially, coins were minted in the form of

  • rectangular ingots made of an alloy of gold and silver. But it turned out that round coins

  • are easier to count and mint. Also, sharp edges on rectangular coins wore out more easily.

  • Stop signs are the only octagonal road signs. This way, they're recognized from afar and

  • distinguished from other road signs even from the backside.

  • Triangular signs warn the driver of hazards on the road. Round signs regulate the traffic

  • speed. And rectangular signs are informative: they give information about localities and

  • routes. TVs are rectangular because movies are made

  • for this screen format. But they used to be round before, since they had round cathode

  • ray tubes (CRTs) inside. And these tubes were round because it was cheaper to produce them

  • like that. But even though the lenses are round, it doesn't

  • matter: the image is projected onto square-shaped film. And it is square because it's easier

  • to use it this way. Camera lenses are round because this is the

  • most convenient form to focus the image. Sugar sticks are elongated because they don't

  • have air inside this way. After all, if the air gets in, there will be moisture, and the

  • sugar hardens. But the main reason is that sugar is very easy to add to tea. You can

  • do it even with one hand. Place the stick on your index and middle fingers and push

  • your thumb on the stick. Previously, sugar was produced in large blocks,

  • and pieces had to be chipped from it. Small square packets appeared after a sugar factory

  • owner's wife cut her finger when trying to chip a piece of sugar from a large block.

  • The director then decided to make sugar that would fit perfectly in the cup.

  • Airplane windows are round for a safer flight. If the aircraft windows were square, pressure

  • and strong airflow would accumulate in their corners, which would lead to loss of pressurization.

  • With rounded windows, the load is distributed and doesn't collect anywhere.

  • According to one theory, the symbol of the heart looks like that because Aristotle described

  • the human heart as a three-chamber structure "with a small dent in the middle." Artists

  • and scientists in the Middle Ages created the first symbol of the heart according to

  • Aristotle's description. Bananas have a curved shape because they try

  • to get closer to the sun while growing. According to the most popular theory, the

  • baguette got a long shape to make it easier to break off. During construction of the Paris

  • subway, the manager was afraid of conflicts between the workers because each of them had

  • a knife to cut bread with. So he asked the company baker to create bread that wouldn't

  • need to be cut. Thus, baguette appeared, and the manager took away the sharp things.

  • The "Turbo" brand gum is different from all the rest because of its unusual shape. It

  • looks like it's been run over by a race car.

  • One of the most popular theories says people used pots made with a special kind of clay

  • called "pygg" to keep coins there. They called it a "pygg" bank. Since the word sounds like

  • "pig," potters started making money jars in the shape of those curly-tailed animals. Thus,

  • we got the "piggy bank." Also, the pig symbolizes prosperity and wealth in many countries.

  • Most water bottles are round not only because it's easier to hold them in your hand, but

  • also because the manufacturer's labels are easier to put on them.

  • The shapes of pasta are so different because a certain kind of it fits a certain sauce.

  • Thin pasta like capellini is more suitable for light sauces and ingredients. Thick, ribbed

  • pasta, like penne, is good for more viscous sauces and vegetable stews.

  • The round Pringles can was made because it's easier to transport. Chips inside have a small

  • chance of being broken. The chips are saddle-shaped for the exact same reason, by the way.

  • Pizza is round for the heat to evenly distribute throughout the pizza while cooking. Also,

  • it's easy to divide into equal parts. And the pizza box is square because it's cheaper

  • in production and easier to fit a round shape into it.

  • Pans are much like pizza: they're round for even distribution of heat and ease of

  • washing. But most importantly, of course, you can throw and catch pancakes while cooking.

  • A hockey puck was originally made from a lacrosse ball. The ball was cut into three parts and

  • the middle was used as a puck. Almost 100 years later, they decided to abandon this

  • tradition and began to glue two pieces of flat rubber from tires. But, such a puck was

  • short-lived. Only in the '90s, the puck took its final form.

  • We don't know exactly who was the first inventor of glasses. In Ancient Rome, people

  • read texts using a round glass bowl filled with water. This inspired people to new ideas,

  • and closer to the 13th century, the first glasses appeared.

  • Other shapes of glasses only came about in the 20th centurybecause of fashion. People

  • realized round glasses didn't fit all head shapes, so the frames began to change shape

  • and size. The lollipop stick has two small holes to

  • fix the candy. When the stick is dipped in hot liquid syrup, it flows through these holes.

  • When it's completely solidified, it holds firmly on the stick.

  • Diamonds are a rare form of carbon that is found deep in the earth's crust. Initially,

  • a diamond's appearance isn't very attractive, but when it's cut and polished, it shines.

  • Most diamonds have a round shape with slightly pointed corners. In this form, a diamond sparkles!

  • The size of a cooking hat depends on the role and status of the kitchen worker. Chefs are

  • kings and queens of the kitchen, so they wear the tallest hats. From a practical point,

  • this is also convenientthanks to the high hat, it's easy to find the chef among

  • the rest of the staff. It's also easier the hide the Rat Chef on your head. (Ratatouille)

  • The number of hat creases indicates the number of ways to cook eggs the chef knows.

  • And that's how it all shapes up!
