The largest padlock in the world (according to Guinness World Records) was created by a team of students and teachers at Russia's Pavlovo Arts College and measures 56.8 inches tall, 41.3 inches wide, and 10.2 inches deep. The total weight of this heavy lock, including the key, is 916 pounds. Whatever it's guarding presumably weighs a lot more!

While Walt Disney invented Mickey Mouse and gave the voice, the visual was developed by animator Ub Iwerks, who designed all of the famous characteristics. You'll never look at the adorable mouse the same way again.

Alexander the Great died at the age of 32, having conquered and established the world's biggest land-based empire. It spanned the Balkans to Pakistan. Alexander became sick in 323 BC and appeared to die after 12 days of intense torment. His corpse, on the other hand, showed no indications of decay or decomposition for a whole six days. Alexander was thought to have suffered from the neurological illness Guillain-Barré Syndrome, according to modern experts. They believe he was just paralysed and intellectually aware when he "died." In other words, he was horrifyingly buried alive!

Though it was not the first film ever made, "The Great Train Robbery" (1903) was the first to tell a story and is widely regarded as the first narrative fiction film. It was produced by Thomas Edison's Edison Studios and was only about 12 minutes long. The filming took place in New Jersey. 

Something frowned upon in most other nations is quite acceptable in China. In China, spitting, yawning, grunting, and burping is normal eating behaviours, just as they are in Vietnam. It was repulsive to us, and we couldn't get used to it. We would bear it better if we stayed in this nation for a little longer.

Under the sea, there are more historic artefacts than in all of the world's museums combined. There are approximately 1,000 shipwrecks off the Florida Keys alone, some of which are protected by the Florida Keys National Marine Sanctuary. Other underwater museums have opened in recent years, including Christ of the Abyss, a submerged bronze statue in the Mediterranean.

The entire ban was based on the discovery of a picture of a swastika-adorned Pooh owned by a single person known for supporting the Nazi party. That was apparently enough to get Winnie banned for good.

With its enormous size and mass, you'd think Jupiter would rotate slowly around its axis. With a rotational velocity of 45,300 km/h, it is the fastest spinning planet in the solar system. As a result, a day on Jupiter lasts only 9 hours and 55 minutes. A year, on the other hand, is much longer; Jupiter orbits the sun once every 11.8 Earth years.

Kites were first seen in America in the mid-1700s, according to history. Benjamin Franklin, one of America's founding fathers, famously flew a kite during a thunderstorm in 1752 to demonstrate an experiment about electricity and nature. This is the first documented kite flight in American history, and Franklin demonstrated that lightning carries electricity. He would later invent the lightning rod as a result of this experiment. What a fascinating fact about kites—it aided one of the world's best inventors in making a fascinating discovery.

A particular female servant with the Queen's shoe size breaks in her new shoes for her. Although Elizabeth II has favored comparable shoes of the same brand for many years, she does not want to suffer the agony that new shoes generally bring.

What could be better than dedicating one day of the year to yourself? Having two of them! Many Greek names are derived from religious saints, each of whom is commemorated by the church on a particular day. People with the same name as the saint are wished a happy name day on that day, and a party is thrown with family, friends, and even neighbours. Marios and Marias, for example, have two name days each year!

As if the Nazis weren't already evil enough, they got dangerously close to producing plutonium, the material that powers nuclear bombs. When the Germans invaded Norway, they seized control of a facility in the Telemark region that manufactured heavy water, which was used to generate plutonium. However, before they could create anything, a group of 11 Norwegian commandos damaged the factory, detonating explosives in the base without incurring a single death.

USA's present 50-star flag was created by 17-year-old Robert Heff as part of a high school project. It was 1958, and there were only 48 states at the moment, but Heft had a feeling Hawaii and Alaska would get statehood shortly. His teacher gave him a B- but later raised the mark to an A after Heft submitted his design to the White House, resulting in a call from President Eisenhower announcing that it had been chosen as the official U.S. flag.

Malaysia is home to the world's biggest cave chamber. The Sarawak Chamber at Gunung Mulu National Park is enormous, with enough capacity for 40-50 Boeing 747s. It's another matter if you could actually park these jets in the Sarawak Chamber...

It's amazing how ancient some of Europe's structures and cities are. Pharmacies are no different. The Raeapteek on Town Hall Square, according to VisitTallinn, is one of Europe's oldest continually running pharmacies. This institution appears to have been in operation since 1422.

Alaska, the biggest state in the United States, was sold for a total of $7.2 million, or roughly 2 cents per acre. In 1867, the state was bought. America made its $7.2 million investment back more than 100 times over in the 50 years that followed. Talk about a good investment.

Yes, truly. Nintendo rented a warehouse in Tukwila, Washington, in 1981 to serve as its American headquarters. According to NPR, when a guy called Mario Segale went into his Nintendo tenants' offices demanding late rent, he created an impression. Even Segale's preference for overalls and short stature appear to have influenced Mario's design over time.

When you think about Greece, you probably see sandy beaches, turquoise seas, whitewashed houses, and blue domes. However, one of the most unexpected facts about Greece is that the bulk of the nation is really made up of mountains. It is one of the most mountainous nations in Europe, with mountains covering 80 percent of the land area. Remember to bring a decent pair of walking shoes!

If you look closely at your zipper, you'll notice the letters YKK, which stand for Yoshida Kogyo Kabushikikaisha. This business, founded in Tokyo in 1934, is believed to create 7 billion zippers every year.

In the year 1897, machine-spin cotton candy was invented by the dentist William Morrison and a confectioner John C Wharton. These candies were first introduced to a wide audience in the year 1904 at 'Fairy Floss' and achieved great success.

Egypt's ancient pyramids were built during an 85-year period, between 2589 and 2504 BC. The Sagrada Familia, Antoni Gaudi's masterwork, began building in 1882 and has continued under development ever since. Gaudi was never able to see his masterpiece completed. After 144 years of development, Barcelona hopes to have it finished by 2026, the 100th anniversary of Gaudi's death.

If you go to Moldova for a vacation, you won't have to compete for space with other tourists: just 121,000 foreigners are believed to have entered the nation in 2016 (according to the UN World Tourism Organization), making it the least visited country in Europe. According to Priceonomics, only Bangladesh and Guinea are less touristic places on a worldwide scale (in terms of tourists per inhabitant).

Algeria is the continent's biggest country, spanning more than 2 million square kilometres and borders Mali, Niger, Libya, Tunisia, Morocco, and Mauritania. This places it above Libya, Sudan, and the Democratic Republic of the Congo, and it is about five times the size of Spain.

Yes, indeed! You may walk by foot between the United States and Russia during certain times of the year, owing to two islands known as Big and Little Diomede. Big Diomede is located in the Russian Federation's easternmost region, whereas Little Diomede is located in Alaskan territory. When the water freezes in the winter, daring visitors can cross the 2.4-mile distance between the two islands. However, you do it at your own peril; while experts believe the voyage is technically feasible, it is risky and not encouraged.
