There is an ancient book full of strange symbols no one can translate

Via Google

The Voynich Manuscript is a curious collection of symbols, drawings, and writings. Women, men, and what appear to be plants are depicted in the pictures, but it's unclear what they're doing. The writing appears to be words, but it is not in any language that can be deciphered. Some folks believe it's a midwifery textbook or a cookbook. Others believe it's a spell book, while others believe it's a scam! People have attempted for years to figure out what it says, but no one has succeeded!

In 1872 a ship was discovered floating in the ocean with no signs of its crew or passengers!

Via Google

It was known as the Mary Celeste, and when passengers boarded, they discovered no one and no trace of a struggle. The ship appeared to be in decent condition, with only a small amount of water at the bottom. What happened to the people aboard the plane? What happened to them? Many explanations have been proposed over the years, including pirates, marine monsters, and even alien abduction! However, it has never been solved. What are your thoughts?

The Tower of London is haunted by lots of ghosts

Via Google

The Tower of London is approximately a thousand years old, giving it plenty of time to amass a large collection of spooks! The ghost of Anne Boleyn, Henry VIII's wife, Lady Jane Grey, the nine-day queen, and even a ghostly bear are among the spectral visitors. There have been many gruesome events in the tower, including murder, torture, beheadings, and more, so it's no surprise these ghosts want to stay! There was also a zoo there, which explains the bear! Have you ever encountered one of these phantoms?

A dead councillor still attends University College London's meetings

Via Google

In 1832, Jeremy Bentham, an 18th-century philosopher, academic, and one of UCL's founders, died. But that didn't stop him from attending council meetings – his skeleton, clothed in his clothes and stuffed with straw, can now be discovered in the halls of UCL, and has been in attendance at UCL council meetings on at least one recorded occasion, in 2013. He is listed as 'Present, but not voting' in the meeting minutes. When you call in ill to school now, I'm sure you're feeling horrible!

The Golden Poison Dart Frog is so poisonous it can kill you with one touch

Via Google

They may appear cute, but their skin is quite dangerous! It is, in fact, one of the most poisonous animals on the planet. The frogs' skin is venomous because they are small and sensitive, making them vulnerable to predators. This little froggy from South America is barely the size of a paperclip, but it packs enough venom to kill up to 20 humans! Scientists aren't sure how the poison is generated, although some believe it comes from the plants the frog eats.

The Mummies of Guanajuato may have been buried alive

Via Google

Guanajuato's mummies are known for their horrifying, dramatic facial expressions (think of your mums face when the dog poos on the carpet). There are around 100 mummies dating back to a 19th century Cholera pandemic, yet only roughly half of them are on display. Some of them may have been buried alive as a result of some of these heinous facial expressions! This is a possibility because cholera wasn't well recognized at the time, and people may have been mistakenly buried alive, believing they were dead. Scary!

There was a Vampire scare in America in the 19th century

Via Google

In the nineteenth century, the New England Vampire Panic happened in New England, USA. Connecticut, Rhode Island, and Vermont are New England states. These so-called "vampires" actually had tuberculosis, which is unfortunately not treated by garlic! Tuberculosis, like the mummies of Guanajuato, was poorly understood and often left the victim looking like the walking dead. Since then, bodies have been excavated that bore the markings of being buried as vampires, including the removal of their heads! The most terrifying aspect is that this occurred less than 200 years ago!

People used to put cat mummies in their walls

Via Google

Yes, you read that correctly. It was once customary in parts of Europe, notably the United Kingdom, to bury the body of a dead cat in the walls of a new home for good luck. Several old structures, especially taverns, have been discovered with mummified cat corpses. For thousands of years, cats have been considered lucky or superstitious by many different cultures, including the ancient Egyptians, who regarded them as particularly precious. Shoes and magical carvings have also been discovered inside old walls. We're not sure what makes a dead cat so lucky...maybe it saves you money on cat food!

Cockroaches can live without their heads for weeks

Via Google

Yes, these hardy insects have been known to go weeks without head! Cockroaches are well-known for their toughness. The neural system of a cockroach is significantly different from ours; they don't need their brains to accomplish most of the work, therefore even if they lose their heads, their nerve systems will continue to function and keep the cockroach moving. They won't die from blood loss, either, because the blood clots in their necks. Unfortunately, when the cockroach requires food and water, it will die. It's clever...but it's also disgusting.

There are tunnels full of skeletons underneath Paris

Via Google

The graveyards in 18th-century Paris were filling up, causing overcrowding and the spread of illness. What is the solution? All of the old bones should be dug up and stored in the city's underground tunnels. They're known as the catacombs, and they're home to millions of people's skeletons! The tunnels themselves date back to mediaeval times, when they were employed as underground quarries. The tunnels stretch for nearly a kilometer, and many of the remains have been placed in complex patterns and designs. If you really want to, you can even pay them a visit! Every year, almost half a million people explore the catacombs!
