Near Santander lies the Altamira cave. In this cave, a lot of prehistoric drawings have been discovered of very varied shapes and meanings. The fun fact about Spain is that this cave is so impressive and of historical importance that people began to call it the Sistine Chapel of Prehistory.

Snow crystals usually form unique patterns, but there has been at least one instance of identical snowflakes in history. Two snowflakes collected from a Wisconsin storm were confirmed to be twins in 1988 at a Colorado atmospheric research centre.

The Pacific Ocean is wider than the moon at its widest point, which stretches from Indonesia to Colombia. This ocean stretches for 12,300 miles, or more than five times the diameter of the moon!

That was Calcutta, after all! During the British Raj, India was a raging hub of all cultures, trade, flourishing cultures, and people. Calcutta, the then-capital of EIC India, is said to have been the second most important city in British colonies around the world after London.

No, flamingos lack mammary glands, but they are nonetheless capable of producing a specific type of "milk" from their upper digestive systems. To feed their offspring, male and female flamingos both make crop milk. Red and white blood cells, protein, and fat are all components of this mixture.

It's true what you just read! Windows 10 may be installed using a USB flash drive. You can quickly and easily upgrade your desktop Windows if you haven't already (where have you been?).

Wisdom teeth, or third molars, usually appear between the ages of 17 and 25. While it varies from person to person, when these teeth appear, they frequently cause problems. Most people have a small jaw, which can cause wisdom teeth to become impacted and unable to break through the gums. Some people's wisdom teeth only partially penetrate their gums, resulting in a flap in their mouth that traps germs. This can result in infections and other problems. Infections, damage to other teeth, and even cysts can result from an impacted teach. Another issue with wisdom teeth is that they are so far back that they can be difficult to clean. This also raises the risk.

Have you ever thought about why you get hiccups? The spasms in your diaphragm compel you to suck in a breath, producing a gulping sound in your voicebox. Hiccups aren't beneficial in today's society, yet they were 370 million years ago. Scientists think that our ancestors had both gills and lungs and that when they pulled water in via their gills, it might aspirate into their lungs. A well-timed hiccup would clear the airway and prevent choking. Even though we no longer have gills, we still love the occasional hiccup!

Tuition expenses at the prestigious University of Geneva, for example, are 500 CHF every semester, or 1000 CHF for the whole academic year. This price range is common at public institutions, however more costly private universities are available. Still, when compared to universities in the United States, it's a steal!

According to the National Sleep Foundation, women are twice as likely as men to suffer from insomnia. Sleeplessness at night is noticed in women due to regular hormonal changes caused by menstruation cycles, pregnancy, menopause, or other comparable factors.

Brown eggs have thicker shells than white eggs, contrary to popular belief. In reality, the thickness of an egg is solely determined by the age of the chicken: younger chickens lay eggs with thicker shells, while older chickens lay eggs with thinner shells. This thickness will occur regardless of the breed of chicken or the colour of the egg.

Rio is Brazil's second largest city, with a population of 6.3 million people. However, it pales in comparison to Sao Paulo, Brazil's largest city, which has a population of 12.04 million people.

When they roll out the red carpet on Oscar night spare a thought for the organizers.

Keeping things as Hollywood as possible, the Academy Awards are held at the impressive Dolby Theatre in the Ovation Hollywood shopping mall every year. Located on Hollywood Boulevard and Highland Avenue, the auditorium first opened in 2001 and has been the home of the Oscars since then.

The average snowflake can be as small as a penny or as large as a human hair. However, some unconfirmed sources claim they can grow much larger. Witnesses to a snowstorm in Fort Keogh, Montana in 1887 reported seeing milk-pan-sized crystals fall from the sky. If this is correct, they would be the largest snowflakes ever seen, measuring about 15 inches across.

The pencil was a favourite of John Steinbeck and Ernest Hemingway. Hemingway wrote letters on a typewriter but did his serious work with a pencil.

Who knew there was so much to know about kites? Aerial warfare has played an important role in history, particularly during both World Wars. Kites were the first air devices used to drop bombs on enemies before planes were invented, let alone used for war. They were also used to communicate and distribute messages through leaflets. Later in the nineteenth century, kites would be used to lift up a soldier for surveillance of their enemies and intelligence gathering.

No, this alleged torture gadget did not exist. The widespread usage of the term "mediaeval" is a typical 18th-century fiction, fueled by conceptions of the Middle Ages as a generally uncivilised era of murder and mayhem. (They weren't awful, but they weren't great.)

Beetroot has been used to cure a wide range of medical conditions, from digestive difficulties to blood-related disorders, since the Middle Ages.

The first tightrope walk occurred in 1859, when Charles Blondin wore pink tights and walked a one-inch-thick tightrope over a part of Niagara Falls. Blondin returned to Niagara Falls numerous times more, including one excursion while blindfolded. In 2012, Nik Wallenda became the first person to walk across the Niagara Falls on a tightrope. Wallenda walked in front of tens of thousands of people and had his journey broadcast live on television.
