Rivers and lakes can be found beneath the ocean. When salt water and hydrogen sulphide combine, it becomes denser than the surrounding water, forming a lake or river that flows beneath the sea.

Human settlers first arrived in Madagascar very recently, probably as late as 500AD, some 300,000 years after Homo sapiens originally appeared in Africa.

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. 

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.

The Tonle Sap supports about half of Cambodia's agriculture and is a key fishing source. The incredible thing about this lake is that it regenerates in major areas throughout the rainy season, when monsoon rain pours and floods the centre area between Siem Reap and Phnom Penh.

While Assassin's Creed is already a household brand, it almost became something quite different. The original crusade-era period game was inspired by a Prince of Persia game called Prince of Persia: Assassin, which had a prince's bodyguard as the protagonist. Unhappy with the thought of a Prince of Persia game not being about a prince (which, interestingly, Nintendo doesn't see as an issue with when it comes to Zelda), Ubisoft's upper brass insisted on a new brand, and Assassin's Creed was created.

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.

Despite the fact that Nazi scientists tried to produce weaponized versions of illnesses such as typhoid and cholera, Hitler banned the employment of offensive biological weapons in war, probably due to his experiences with bioweapons during World War I.

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.

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.

Santa Claus parades are held in a variety of places, and each one is unique in its own way. The parade in Peoria, Illinois, on the other hand, is the oldest of its sort in the United States. It's been going on every Christmas season since 1888—that's well over a century of festive pleasure!

Muammar Gaddafi took power in Libya in 1969 and reigned for 42 years. As a result, he became one of Africa's and the world's longest-serving leaders of state. Gaddafi was well-known for being a despotic ruler. He did, however, serve his country well by increasing health care to the point that it was among the finest in Africa. He also boosted Libya's literacy rate from 25 percent to 87 percent during his tenure. When he was removed from power in 2011, his reign came to an end. The militia hunted him down and murdered him in his hometown, where he had sought safety. Gaddafi's net worth was $200 billion at the time of his death.

The most expensive coffee on the planet is "Kopi Luwak." It is made in Indonesia from beans digested by the Asian Palm Civet. That is, it is derived from cat poop. It can cost up to €350 per kilo!

Hot chocolate was not something we were served in restaurants these days. Cocoa was brewed in both Aztec and Mexican cultures, but it was nothing like the hot chocolate we have today. It was primarily a bitter concoction that was frequently consumed at weddings and other special occasions. Many people used it as a medicine or as a base for other medications.

Texas is where German chocolate cake was invented. The "German" in German chocolate cake is the work of an American man, not a European country. It is named after Sam German, who created the formula for a mild dark baking chocolate bar for Baker's Chocolate Company in 1852, which was later renamed Baker's German's Sweet Chocolate. Let's go back to June 13, 1957. According to What's Cooking America, the Dallas Morning Star published the recipe for the cake, which was invented and submitted by a reader identified as Mrs. George Clay.

Hüseyin Kalkan, the mayor of Batman (a town in southern Turkey), sought to sue Warner Bros. and Christopher Nolan in 2008 for exploiting the town's name without authorization. Despite saying that there was only one Batman in the world, there was no true news about it after that. Batman originally debuted in a comic book in 1939. The issue is, which came first, the chicken or the egg? Which came first, the chicken or the egg?

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...

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!

The origins of this strange-sounding celebration may be traced back hundreds of years, beginning in the early 1900s. People did not have refrigerators in the 1900s, so they hung a piece of cloth in their larders. It is thought that doing so provided the home good fortune, tranquilly, and wealth. The tradition evolved to accommodate the contemporary kitchen throughout time. Every year on May 29th, families throughout the world place a pillow on top of their refrigerator.

Dubai claims to have the world's largest picture frame. The 492-foot-tall Dubai Frame soars above the city's skyline and is a popular tourist attraction.

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.

Edison was, without a doubt, one of the world's most renowned intellectual property thieves. He stole nearly all of the 1,093 things he smashed a patent on from real geniuses like Nikola Tesla, Wilhelm Rontgen, and Joseph Swan – the latter of whom invented the lightbulb!
