9 Deep Facts About the Dead Sea

The Dead Sea is one of the most intriguing and interesting lakes in the world. Located at the lowest point on Earth, tourists from around the globe flock to this hypersaline phenomenon, which borders Jordan to the east and Israel and the West Bank to the west. Dive into these nine fascinating facts about the "Salt Sea."

1. IT WAS FORMED FROM A RIFT IN THE EARTH'S CRUST.

The Dead Sea came to be because the crust was stretched thanks to a rift being formed. Known as a rift valley, the surface sunk down where the crust was particularly thin. Scientists estimate the Dead Sea may be sinking more each year, so book your tickets ASAP.

2. IT’S LOCATED AT THE LOWEST POINT ON EARTH.

The surface of the Dead Sea is over 1300 feet below sea level, making it the lowest point on Earth's surface. In the deepest part, it’s more than 2300 feet below sea level. It’s located on the edge of the Judean Desert, a very hot region at the foot of the Ha-He'etekim cliff. It’s close to Jerusalem, and the connecting point between the desert and developed land in the Middle East.

3. IT MAY HAVE INCREDIBLE HEALING POWERS.

When doctors prescribe a visit to the Dead Sea for their patients as a source of healing, you know something special is going on. With up to 32 percent salt and extremely high mineral content, the water is said to help people with respiratory issues, joint problems like arthritis, and many chronic skin conditions such as psoriasis, acne, and cellulite. As you go farther into the water, this land-locked lake becomes saltier. The low UV rays from the sun and bromide in the air also contribute to natural healing.

4. IT’S ONE OF THE WORLD'S SALTIEST BODIES OF WATER.

No need for flotation devices. Our bodies are more buoyant in the Dead Sea because of the high concentration of mineral salts that have dissolved. The Dead Sea is eight times saltier than the oceans and has the highest concentration of salt of any body of water in the world—so rather than swim, visitors literally float around. In fact, don’t even try to swim; it won't work.

5. IT’S BEEN A PLACE OF REFUGE SINCE BIBLICAL TIMES.

The Dead Sea is cited in the Hebrew Bible during the rule of King David as a place where he sought refuge. This famous sea is also mentioned in other biblical books throughout history. The first tourist to visit the Dead Sea was most likely Abraham. (Unfortunately there are no photos of Abraham slathering black mud on his skin or floating in the Dead Sea reading the newspaper to back this up.)

6. NO PLANTS OR ANIMALS CAN LIVE IN THE WATER.

No creatures can survive in the Dead Sea, which means no jumping dolphins, no swimming fish, and no seaweed to get stuck between your toes. The massive levels of salt prevent the existence of all life forms, except some bacteria discovered in recent years. Needless to say, don’t drink the water!

7. DEAD SEA MUD IS GREAT FOR YOUR SKIN.

Almost as famous as the sea itself are the images of tourists slathering mud on their bodies, letting it harden, and then rinsing it off in the sea (as much as you can rinse off dried mud with salt water). The deposits of black mud come directly from the seabed. The mud is beneficial to your skin as it is high in magnesium, sodium, potassium, and calcium. Looking to purchase this world-famous mud in North America? No problem. Dead Sea mud and minerals are available online through AHAVA.

8. IT’S THE BIGGEST FREE SPA ON EARTH.

With all that healing mud, the Dead Sea is quite literally the biggest natural free spa on earth. But should you feel the need to indulge in further spa treatments, there are multiple hotels to choose from in the area that offer rejuvenating spa services, including the famous Ein Gedi Hotel.

9. YES, THE DEAD SEA SCROLLS WERE FOUND HERE.

The Dead Sea Scrolls were found hidden in a cave in Qumran and contain some of the oldest copies ever discovered of the Hebrew Bible. They have been called the greatest archaeological find of the 20th century. Portions of the Dead Sea Scrolls now make the occasional tour at various museums so we can learn about their significant history.

15 Must-See Holiday Horror Movies
Echo Bridge Home Entertainment
Echo Bridge Home Entertainment

Families often use the holidays as an excuse to indulge in repeat viewings of Planes, Trains and Automobiles and Elf. But for a certain section of the population, the yuletide is all about horror. Although it didn’t truly emerge until the mid-1970s, “holiday horror” is a thriving subgenre that often combines comedy to tell stories of demented Saint Nicks and lethal gingerbread men. If you’ve never seen Santa slash someone, here are 15 movies to get you started.

1. THANKSKILLING (2009)

Most holiday horror movies concern Christmas, so ThanksKilling is a bit of an anomaly. Another reason it’s an anomaly? It opens in 1621, with an axe-wielding turkey murdering a topless pilgrim woman. The movie continues on to the present-day, where a group of college friends are terrorized by that same demon bird during Thanksgiving break. It’s pretty schlocky, but if Turkey Day-themed terror is your bag, make sure to check out the sequel: ThanksKilling 3. (No one really knows what happened to ThanksKilling 2.)

2. BLACK CHRISTMAS (1974)

Fittingly, the same man who brought us A Christmas Story also brought us its twisted cousin. Before Bob Clark co-wrote and directed the 1983 saga of Ralphie Parker, he helmed Black Christmas. It concerns a group of sorority sisters who are systematically picked off by a man who keeps making threatening phone calls to their house. Oh, and it all happens during the holidays. Black Christmas is often considered the godfather of holiday horror, but it was also pretty early on the slasher scene, too. It opened the same year as The Texas Chainsaw Massacre and beat Halloween by a full four years.

3. SILENT NIGHT, DEADLY NIGHT (1984)

This movie isn’t about Santa Claus himself going berserk and slaughtering a bunch of people. But it is about a troubled teen who does just that in a Santa suit. Billy Chapman starts Silent Night, Deadly Night as a happy little kid, only to witness a man dressed as St. Nick murder his parents in cold blood. Years later, after he has grown up and gotten a job at a toy store, he conducts a killing spree in his own red-and-white suit. The PTA and plenty of critics condemned the film for demonizing a kiddie icon, but it turned into a bona fide franchise with four sequels and a 2012 remake.

4. RARE EXPORTS: A CHRISTMAS TALE (2010)

This Finnish flick dismantles Santa lore in truly bizarre fashion, and it’s not easy to explain in a quick plot summary. But Rare Exports involves a small community living at the base of Korvatunturi mountain, a major excavation project, a bunch of dead reindeer, and a creepy old naked dude who may or may not be Santa Claus. Thanks to its snowy backdrop, the movie scored some comparisons to The Thing, but the hero here isn’t some Kurt Russell clone with equally feathered hair. It’s a bunch of earnest kids and their skeptical dads, who all want to survive the holidays in one piece.

5. TO ALL A GOODNIGHT (1980)

To All a Goodnight follows a by-now familiar recipe: Add a bunch of young women to one psycho dressed as Santa Claus and you get a healthy dose of murder and this 1980 slasher flick. Only this one takes place at a finishing school. So it’s fancier.

6. KRAMPUS (2015)

Although many Americans are blissfully unaware of him, Krampus has terrorized German-speaking kids for centuries. According to folklore, he’s a yuletide demon who punishes naughty children. (He’s also part-goat.) That’s some solid horror movie material, so naturally Krampus earned his own feature film. In the movie, he’s summoned because a large suburban family loses its Christmas cheer. That family has an Austrian grandma who had encounters with Krampus as a kid, so he returns to punish her descendants. He also animates one truly awful Jack-in-the-Box.

7. THE GINGERDEAD MAN (2005)

“Eat me, you punk b*tch!” That’s one of the many corny catchphrases spouted by the Gingerdead Man, an evil cookie possessed by the spirit of a convicted killer (played by Gary Busey). The lesson here, obviously, is to never bake.

8. JACK FROST (1997)

No, this isn’t the Michael Keaton snowman movie. It’s actually a holiday horror movie that beat that family film by a year. In this version, Jack Frost is a serial killer on death row who escapes prison and then, through a freak accident, becomes a snowman. He embarks on a murder spree that’s often played for laughs—for instance, the cops threaten him with hairdryers. But the comedy is pretty questionable in the infamous, and quite controversial, Shannon Elizabeth shower scene.

9. ELVES (1989)

Based on the tagline—“They’re not working for Santa anymore”—you’d assume this is your standard evil elves movie. But Elves weaves Nazis, bathtub electrocutions, and a solitary, super grotesque elf into its utterly absurd plot. Watch at your own risk.

10. SINT (2010)

The Dutch have their own take on Santa, and his name is Sinterklaas. Sinterklaas travels to the Netherlands via steamship each year with his racist sidekick Zwarte Piet. But otherwise, he’s pretty similar to Santa. And if Santa can be evil, so can Sinterklaas. According to the backstory in Sint (or Saint), the townspeople burned their malevolent bishop alive on December 5, 1492. But Sinterklaas returns from the grave on that date whenever there’s a full moon to continue dropping bodies. In keeping with his olden origins, he rides around on a white horse wielding a golden staff … that he can use to murder you.

11. SANTA’S SLAY (2005)

Ever wonder where Santa came from? This horror-comedy claims he comes from the worst possible person: Satan. The devil’s kid lost a bet many years ago and had to pretend to be a jolly gift-giver. But now the terms of the bet are up and he’s out to act like a true demon. That includes killing Fran Drescher and James Caan, obviously.

12. ALL THROUGH THE HOUSE (2015)

Another Santa slasher is on the loose in All Through the House, but the big mystery here is who it is. This villain dons a mask during his/her streak through suburbia—and, as the genre dictates, offs a bunch of promiscuous young couples along the way. The riddle is all tied up in the disappearance of a little girl, who vanished several years earlier.

13. CHRISTMAS EVIL (1980)

Several years before Silent Night, Deadly Night garnered protests for its anti-Kringle stance, Christmas Evil put a radicalized Santa at the center of its story. The movie’s protagonist, Harry Stadling, first starts to get weird thoughts in his head as a kid when he sees “Santa” (really his dad in the costume) groping his mom. Then, he becomes unhealthily obsessed with the holiday season, deludes himself into thinking he’s Santa, and goes on a rampage. The movie is mostly notable for its superfan John Waters, who lent commentary to the DVD and gave Christmas Evil some serious cult cred.

14. SANTA CLAWS (1996)

If you thought this was the holiday version of Pet Sematary, guess again. The culprit here isn’t a demon cat in a Santa hat, but a creepy next-door neighbor. Santa Claws stars B-movie icon Debbie Rochon as Raven Quinn, an actress going through a divorce right in the middle of the holidays. She needs some help caring for her two girls, so she seeks out Wayne, her neighbor who has an obsessive crush on her. He eventually snaps and dresses up as Santa Claus in a ski mask. Mayhem ensues.

15. NEW YEAR’S EVIL (1980)

Because the holidays aren’t over until everyone’s sung “Auld Lang Syne,” we can’t count out New Year’s Eve horror. In New Year’s Evil, lady rocker Blaze is hosting a live NYE show. Everything is going well, until a man calls in promising to kill at midnight. The cops write it off as a prank call, but soon, Blaze’s friends start dropping like flies. Just to tie it all together, the mysterious murderer refers to himself as … “EVIL.”

10 Surprising Ways Senses Shape Perception
The American Museum of Natural History
The American Museum of Natural History

Every bit of information we know about the world we gathered with one of our five senses. But even with perfect pitch or 20/20 vision, our perceptions don’t always reflect an accurate picture of our surroundings. Our brain is constantly filling in gaps and taking shortcuts, which can result in some pretty wild illusions.

That’s the subject of “Our Senses: An Immersive Experience,” a new exhibition at the American Museum of Natural History in New York City. Mental Floss recently took a tour of the sensory funhouse to learn more about how the brain and the senses interact.

1. LIGHTING REVEALS HIDDEN IMAGES.

Under normal lighting, the walls of the first room of “Our Senses” look like abstract art. But when the lights change color, hidden illustrations are revealed. The three lights—blue, red, and green—used in the room activate the three cone cells in our eyes, and each color highlights a different set of animal illustrations, giving the viewers the impression of switching between three separate rooms while standing still.

2. CERTAIN SOUNDS TAKE PRIORITY ...

We can “hear” many different sounds at once, but we can only listen to a couple at a time. The AMNH exhibit demonstrates this with an audio collage of competing recordings. Our ears automatically pick out noises we’re conditioned to react to, like an ambulance siren or a baby’s cry. Other sounds, like individual voices and musical instruments, require more effort to detect.

3. ... AS DO CERTAIN IMAGES.

When looking at a painting, most people’s eyes are drawn to the same spots. The first things we look for in an image are human faces. So after staring at an artwork for five seconds, you may be able to say how many people are in it and what they look like, but would likely come up short when asked to list the inanimate object in the scene.

4. PAST IMAGES AFFECT PRESENT PERCEPTION.

Our senses often are more suggestible than we would like. Check out the video above. After seeing the first sequence of animal drawings, do you see a rat or a man’s face in the last image? The answer is likely a rat. Now watch the next round—after being shown pictures of faces, you might see a man’s face instead even though the final image hasn’t changed.

5. COLOR INFLUENCES TASTE ...

Every cooking show you’ve watched is right—presentation really is important. One look at something can dictate your expectations for how it should taste. Researchers have found that we perceive red food and drinks to taste sweeter and green food and drinks to taste less sweet regardless of chemical composition. Even the color of the cup we drink from can influence our perception of taste.

6. ... AND SO DOES SOUND

Sight isn’t the only sense that plays a part in how we taste. According to one study, listening to crunching noises while snacking on chips makes them taste fresher. Remember that trick before tossing out a bag of stale junk food.

7. BEING HYPER-FOCUSED HAS DRAWBACKS.

Have you ever been so focused on something that the world around you seemed to disappear? If you can’t recall the feeling, watch the video above. The instructions say to keep track of every time a ball is passed. If you’re totally absorbed, you may not notice anything peculiar, but watch it a second time without paying attention to anything in particular and you’ll see a person in a gorilla suit walk into the middle of the screen. The phenomenon that allows us to tune out big details like this is called selective attention. If you devote all your mental energy to one task, your brain puts up blinders that block out irrelevant information without you realizing it.

8. THINGS GET WEIRD WHEN SENSES CONTRADICT EACH OTHER.

The most mind-bending room in the "Our Senses" exhibit is practically empty. The illusion comes from the black grid pattern painted onto the white wall in such a way that straight planes appear to curve. The shapes tell our eyes we’re walking on uneven ground while our inner ear tells us the floor is stable. It’s like getting seasick in reverse: This conflicting sensory information can make us feel dizzy and even nauseous.

9. WE SEE SHADOWS THAT AREN’T THERE.

If our brains didn’t know how to adjust for lighting, we’d see every shadow as part of the object it falls on. But we can recognize that the half of a street that’s covered in shade isn’t actually darker in color than the half that sits in the sun. It’s a pretty useful adaptation—except when it’s hijacked for optical illusions. Look at the image above: The squares marked A and B are actually the same shade of gray. Because the pillar appears to cast a shadow over square B, our brain assumes it’s really lighter in color than what we’re shown.

10. WE SEE FACES EVERYWHERE.

The human brain is really good at recognizing human faces—so good it can make us see things that aren’t there. This is apparent in the Einstein hollow head illusion. When looking at the mold of Albert Einstein’s face straight on, the features appear to pop out rather than sink in. Our brain knows we’re looking at something similar to a human face, and it knows what human faces are shaped like, so it automatically corrects the image that it’s given.
