13 Mysterious Details on Everyday Objects Explained

We’re so used to seeing certain everyday objects that we often ignore their little but important details. Yet, some of the most ingenious ideas are often hidden right in plain sight. If you look closely at a tram's overhead lines, you'll see that its contact wires zigzag back and forth instead of going in a straight line. As the tram moves, the arm-like structure called a pantograph attached to its roof slides along the wire, and it wears down evenly. In a standard 52-deck of cards, the King of Hearts looks kind of strange. Some historians argue that the King of Hearts represents Ajax the Great while the Queen of Hearts is Helen of Troy, the most beautiful woman in the world. Ajax was one Helen’s admirers, but when she refused him, he chose to commit suicide by stabbing himself with his own sword. Have you ever noticed how many spikes are in the crown of the Statue of Liberty, and do you know what they represent? There are seven of them, and they represent the seven seas and seven continents of the world. Is your first thought when playing video game consoles to eat the cartridges? Well, apparently that’s what the manufacturers of the cartridges for the Nintendo Switch thought when they decided to coat them with a bitter-tasting non-toxic solution. Most people assume that the tiny hole on the tip of a pen cap is there to even out the pressure so that the pen doesn’t leak. In fact, it’s to save a person who might accidentally swallow the cap and choke on it. Their airway won't be completely obstructed. w:Period-after-opening symbol on a bottle of mouthwash: By I, Trounce, CC BY-SA 3.0 https://creativecommons.org/licenses/by-sa/3.0, https://commons.wikimedia.org/w/index.php?curid=2389837 Animation is created by Bright Side.

To wear it down evenly, the wire isn’t installed strictly along the tram's straight path but in a zigzag instead. -There are 3 theories explaining why the King of Hearts is the only king who appears to be sticking his sword straight into his head. -When the one-, two-, five-, ten-, twenty-, and fifty-pence pieces are laid out together, they form The Royal Coat of Arms of the UK. -To find out how long you can safely use your makeup for, look for the little open jar icon called the PAO (Period After Opening). -The Statue of Liberty has seven spikes in her crown, and they represent the seven seas and seven continents of the world. -Book pages are often printed on large sheets of paper rather than on small individual ones. And if there isn't enough content to fill these sheets, there will be blank pages. -It turns out that each stripe in the toothpaste has different ingredients and purposes: the white part helps whiten your teeth and remove plaque, the blue (or green) gel has antimicrobial and breath-freshening effects. The red part contains crucial elements for healthy gums. -The bitter taste of the cartridges for the Nintendo Switch is meant to make children spit out the cartridge in disgust. -The numbers in the upper right corner of Heinz packets indicate which filling line the packet was filled on. - If a person accidentally swallows the ballpoint pen cap and chokes on it, their airway won't be completely obstructed thank to the little hole in it. -The little bumps on the “F” and “J” on the keyboard help experienced typists that can do their work without looking at the keyboard find “home keys” where the index fingers rest. -Indentations on the bottom of wine and champagne bottles are there to prevent because the bottom and sides of the bottle from cracking when the bottle is being corked. -Tiny holes in airplane windows help balance out the air pressure and prevent the windows from fogging up.

10 Oldest Technologies Scientists Still Can’t Explain

Thousands of years ago great minds managed to create incredible technologies that were way ahead of their time, like a fire that couldn’t be extinguished by water, an unbreakable medieval sword, and even an ancient computer from 200 B.C.E.! You’d be surprised to find out what crazy inventions existed back then that science still can’t explain today. If you’re ready to learn more about these mind-blowing ancient inventions plus a whole lot more, then keep on watching. TIMESTAMPS The stone globes of Costa Rica 0:59 The Roman dodecahedron 3:16 The Phaistos Disk in Crete 4:48 Greek fire 6:14 Damascus steel 7:31 The Iron pillar of Delhi 8:37 The Viking Ulfberht sword 10:11 The Voynich manuscript 11:56 The Zhang Heng seismograph 14:06 The Antikythera mechanism 15:12 #oldtechnology #damascucsteel #viking Music: https://www.youtube.com/audiolibrary/music SUMMARY -Granodiorite rocks can easily be carved using temperature techniques. Hundreds of stone spheres were found quarried in the foothills of the Talamanca Mountains. Researchers even saw a gigantic ball weighing over 16 tons. -The Roman dodecahedron had 12 flat pentagon-shaped faces with a knob protruding on each corner. It might have been a dice, a kid’s toy, a candle holder, a simple decoration, a measuring device on the battlefield, or an astronomical instrument, to name a few. -The Phaistos Disk was made from clay and measures about 6.2 inches in diameter. Experts concluded that it was a prayer to an ancient Minoan goddess. -The formula of Greek fire was a well-guarded state secret for over 7 centuries. Greek fire was used in naval warfare. -Blades made from Damascus steel were the most sought after in medieval Europe. And that’s because they were the best swords at the time. -The Iron pillar of Delhi dates back to the Gupta period, which lasted from about 240 to 590 C.E. A small amount of rust has started to form, but it is strange that there isn’t more. -Viking Ulfberht swords are believed to have been made around 800 to 1,000 C.E., but experts were sure that the technology used to make swords of such extraordinary quality didn’t come around until 800 years later. -The Voynich manuscript has 240 pages broken up into four sections: herbal, astrological, balneological, and pharmacological. There have literally been dozens of failed attempts to crack this thing. -In 132 C.E., Zhang Heng, a Chinese inventor, astronomer, engineer, scientist, scholar, and artist, invented a seismoscope and presented it to the Han court as an instrument for measuring seasonal winds and the Earth’s movements. -The Antikythera mechanism was retrieved by a group of divers in 1900 and has been dubbed “the world’s first analog computer” and it was made around 200 B.C.E.

10 Strange Facts About Cleopatra Teachers Never Told You

Whether you’ve seen her portrayed on the big screen, you learned about her in school, or probably a combination of both, Cleopatra is definitely one of the most well-known names out there! She was the last Egyptian pharaoh and without a doubt one of the most influential women in the history of humankind. But because the story of the queen’s life has been told in so many books and movies, it can be hard to separate historical facts from fiction. But we’re about to bust some of the most popular myths about Cleopatra and open your eyes to several peculiar facts of her real biography. TIMESTAMPS Cleopatra married two of her younger brothers. 1:15 Julius Caesar erected a statue of her in the Temple of Venus Genetrix. 2:40 Mark Antony once skipped an invasion to spend time with Cleo. 4:10 She wasn’t exactly a beauty. 5:14 Cleopatra wasn't just a ruler, she was a mother too. 5:56 She loved spending money, but not only on herself. 6:31 Cleopatra might not have died from a snake bite. 6:55 She could speak Egyptian Arabic. 7:40 Cleopatra's famous makeup was a sort of protection. 8:45 Cleopatra owned a perfume factory. 9:37 Bonus: Cleopatra spent money on a cocktail that would be equivalent to over $16 million today 10:21 #cleopatrafacts #cleo #juliuscaesar Music: https://www.youtube.com/audiolibrary/music SUMMARY -Cleopatra ended up marrying her little brother, Ptolemy XIII, who was just 10 at the time. After his death, which occurred several years later, she married her other brother, Ptolemy XIV. -Caesar erected a statue of Cleopatra in the Venus Temple in Rome. -Cleopatra showed up to her first meeting with Mark Antony dressed as the Greek goddess Aphrodite. To no surprise, Mark Antony was impressed, and that's how their partnership started. -Her contemporaries saw her beauty not so much in her looks but in her wit, character, and irresistible charisma. -While Cleopatra didn't have any children with her brothers, she did have kids from both Julius Caesar and Mark Antony. -Cleopatra did spend around 50% of her share of the kingdom’s income on beauty and other luxuries. But she was also an extremely efficient ruler who cared about her people. -Ancient historian Strabo wrote that Cleopatra always had a comb soaked in poison with her, so she possibly could’ve killed herself with it. -People in Cleopatra's family spoke Greek and had Greek traditions. Cleopatra was the first in her family to accept the local culture, ancient customs, and Egyptian gods. -Cleopatra’s makeup contained 4 lead-based substances and was used to fend off eye infections, which were common in Ancient Egypt. -The ruins of Cleopatra’s perfume factory were found near Ein Gedi, which is situated on the Dead Sea. That place was also used as a beauty salon and spa. -Cleopatra once had a bet with Mark Antony that she could spend 10 million sesterces, equivalent to $16.7 million today on just one dinner.

What do you know about ur planet? Many things seem to have existed forever, and certain well-known people are associated with a specific period of time. But have you ever really sat down and considered the relationship between different events in correlation with each other? You’d be surprised how your perception of time really fools you!

By the way, we’ve hidden 3 tiny light bulbs in this video. Can you find them all? If you’re the first one to find them and write the time they appear in the comments, you will get a mention from us in one of our next videos! Good luck, and let’s begin!

TIMESTAMPS

SUMMARY
- The first Star Wars movie was released on May 25, 1977. After that, France officially abolished the use of the guillotine along with the death penalty 1981!
- For example, it's still morning in the US but already the next day in Australia. Anyone who has flown westward over long distances especially gets what we’re saying. You’re travelling for hours and hours but, according to the local time, you arrive to your destination earlier than when you had left!
- The famous American preacher and 1960’s civil rights leader was born in the same year as Anne Frank, a brave little Jewish teenager.
- By the time Cleopatra was born in 69 B.C., the Great Pyramid of Giza had already been around for 2,471 years!
- Herman Melville wrote Moby-Dick in 1851. In his book, the author described a gigantic white whale infamous for its huge size and the destruction it caused to ships. And while such whales have a lifespan of about 50-60 years, the Bowhead whale can live for as long as 200 years and more!
- What happened was a Hawaiian plane took off from Auckland at 12:05AM on January 1, 2018. The passengers on the plane were happy to celebrate the New Year a second time because the plane landed in Honolulu at 10:16AM local time on December 31, 2017.
- John Tyler was born in 1790; that’s over 200 years ago! Yet 2 of his grandchildren, Lyon Gardiner Tyler Junior and Harisson Raffin Tyler, are still alive. Yes, grandchildren!
- In 1903 the Warner brothers opened their first movie theater called the Cascade. Their parents were originally from the Russian Empire, and out of 12 children in the family, it was actually just Harry, Albert, Sam, and Jack that started the famous company.
- Elizabeth II was born in 1926 when Calvin Coolidge was President of the US. Since then, there have been 15 successors.
- The Italy we know today, aka the Italian Republic, was established in 1861, and Charles Lewis Tiffany and John Young opened their first store on Broadway in 1837. But you probably wouldn’t have recognized the company in its early years.
- Let's imagine the Earth’s 4.54 billion-year history is squished into one calendar year. If you crunch the numbers, you’ll see that 1 second would equal 144 years!
- When you hear "10 years ago," you still think of the '90s, not the 2000s, don't you? Isn’t it crazy how so many people are guilty of this? Well, here’s a friendly reminder: it’s been 18 years since the year 2000 (and 28 since 1990!)
