What’s the Origin of Jack-O’-Lanterns?

The term "jack-o'-lantern" was first applied to people, not pumpkins. As far back as 1663, the term meant a man with a lantern, or a night watchman. Just a decade or so later, it began to be used to refer to the mysterious lights sometimes seen at night over bogs, swamps, and marshes.

These ghost lights—variously called  jack-o’-lanterns, hinkypunks, hobby lanterns, corpse candles, fairy lights, will-o'-the-wisps, and fool's fire—are created when gases from decomposing plant matter ignite as they come into contact with electricity or heat or as they oxidize. For centuries before this scientific explanation was known, people told stories to explain the mysterious lights. In Ireland, dating as far back as the 1500s, those stories often revolved around a guy named Jack.

LEGEND HAS IT

As the story goes, Stingy Jack—often described as a blacksmith—invited the devil to join him for a drink. Stingy Jack didn't want to pay for the drinks from his own pocket, and convinced the devil to turn himself into a coin that could be used to settle the tab. The devil did so, but Jack skipped out on the bill and kept the devil-coin in his pocket with a silver cross so that the devil couldn’t shift back to his original form. Jack eventually let the devil loose, but made him promise that he wouldn’t seek revenge on Jack, and wouldn’t claim his soul when he died.

Later, Jack irked the devil again by convincing him to climb up a tree to pick some fruit, then carved a cross in the trunk so that the devil couldn’t climb back down (apparently, the devil is a sucker). Jack freed him again, on the condition that the devil once again not take revenge and not claim Jack’s soul.

When Stingy Jack eventually died, God would not allow him into heaven, and the devil, keeping his word, rejected Jack’s soul at the gates of hell. Instead, the devil gave him a single burning coal to light his way and sent him off into the night to “find his own hell.” Jack put the coal into a carved-out turnip and has supposedly been roaming the earth with it ever since. In Ireland, the ghost lights seen in the swamps were said to be Jack’s improvised lantern moving about as his restless soul wandered the countryside. He and the lights were dubbed "Jack of the Lantern," or "Jack O'Lantern."

OLD TALE, NEW TRADITIONS

The legend immigrated to the new world with the Irish, and it collided with another old world tradition and a new world crop. Making vegetable lanterns was a tradition of the British Isles, and carved-out turnips, beets, and potatoes were stuffed with coal, wood embers, or candles as impromptu lanterns to celebrate the fall harvest. As a prank, kids would sometimes wander off the road with a glowing veggie to trick their friends and travelers into thinking they were Stingy Jack or another lost soul. In America, pumpkins were easy enough to come by and good for carving, and got absorbed both into the carved lantern tradition and the associated prank. Over time, kids refined the prank and began carving crude faces into the pumpkins to kick up the fright factor and make the lanterns look like disembodied heads. By the mid-1800s, Stingy Jack’s nickname was applied to the prank pumpkin lanterns that echoed his own lamp, and the pumpkin jack-o’-lantern got its name.

Toward the end of the 19th century, jack-o’-lanterns went from just a trick to a standard seasonal decoration, including at a high-profile 1892 Halloween party hosted by the mayor of Atlanta. In one of the earliest instances of the jack-o’-lantern as Halloween decor, the mayor’s wife had several pumpkins—lit from within and carved with faces—placed around the party, ending Jack O’Lantern’s days of wandering, and beginning his yearly reign over America’s windowsills and front porches.

What Happens When You Flush an Airplane Toilet?

For millions of people, summer means an opportunity to hop on a plane and experience new and exciting sights, cultures, and food. It also means getting packed into a giant commercial aircraft and then wondering if you can make it to your next layover without submitting to the anxiety of using the onboard bathroom.

Roughly the size of an apartment pantry, these narrow facilities barely accommodate your outstretched knees; turbulence can make expelling waste a harrowing nightmare. Once you’ve successfully managed to complete the task and flush, what happens next?

Unlike our home toilets, planes can’t rely on water tanks to create passive suction to draw waste from the bowl. In addition to the expense of hauling hundreds of gallons of water, it’s impractical to leave standing water in an environment that shakes its contents like a snow globe. Originally, planes used an electronic pump system that moved waste along with a deodorizing liquid called Anotec. That method worked, but carrying the Anotec was undesirable for the same reasons as storing water: It raised fuel costs and added weight to the aircraft that could have been allocated for passengers. (Not surprisingly, airlines prefer to transport paying customers over blobs of poop.)

Beginning in the 1980s, planes used a pneumatic vacuum to suck liquids and solids down and away from the fixture. Once you hit the flush button, a valve at the bottom of the toilet opens, allowing the vacuum to siphon the contents out. (A nonstick coating similar to Teflon reduces the odds of any residue.) It travels to a storage tank near the back of the plane at high speeds, ready for ground crews to drain it once the airplane lands. The tank is then flushed out using a disinfectant.

If you’re also curious about timing your bathroom visit to avoid people waiting in line while you void, flight attendants say the best time to go is right after the captain turns off the seat belt sign and before drink service begins.

Why is Friday the 13th Considered Unlucky?

Today, people around the globe will feel uneasy about getting out of bed, leaving their homes, or going about their normal daily routines, all because of a superstition. These unfortunate folks suffer from paraskavedekatriaphobia, a common neurosis familiar to us all: the fear of Friday the 13th. But just where did this superstitious association come from, and how did it catch on?

The truth is that no one is absolutely sure where the idea that Friday the 13th is unlucky originated. Donald Dossey, the founder of the Stress Management Center and Phobia Institute in Asheville, North Carolina, suspects the fear can be traced back to a Norse myth about 12 gods who had a dinner at Valhalla—the fabled hall where legendary Norse heroes feasted for eternity after they died—that was interrupted by a 13th guest, the evil and mischievous god Loki.

According to legend, Loki tricked Höðr (the blind god of winter and son of Odin, the supreme god in Norse mythology) into shooting his brother Baldr (the benevolent god of summer who was also a son of Odin) with a magical spear tipped with mistletoe—the only substance that could defeat him. Thus the number 13 was branded as unlucky because of the ominous period of mourning following the loss of such powerful gods by this unwanted 13th guest.

For whatever reason, among many cultures, the number 12 emerged throughout history as a "complete" number: There are 12 months in a year, 12 signs of the zodiac, 12 Gods of Olympus, 12 sons of Odin, 12 labors of Hercules, 12 Jyotirlingas or Hindu shrines where Shiva is worshipped, 12 successors of Muhammad in Shia Islam, and 12 tribes of Israel. In Christianity, Jesus was betrayed by one of his 12 Apostles—Judas—who was the 13th guest to arrive for the Last Supper. Surpassing the number 12 ostensibly unbalances the ideal nature of things; because it is seen as irregular and disrespectful of a sense of perfection, the number 13 bears the stigma of misfortune and bad luck we know today.

WHY FRIDAY?

Friday joins in the mix mostly because all of the early accounts of Jesus’s crucifixion agree that it took place on Friday—the standard day for crucifixions in Rome. As Chaucer noted in The Canterbury Tales, "And on a Friday fell all this mischance." Yet perpetuating Friday as an unlucky day in America came from the late 19th-century American tradition of holding all executions on Fridays; Friday the 13th became the unluckiest of days simply because it combined two distinct superstitions into one. According to the Oxford University Press Dictionary of Superstitions, the first reference to Friday the 13th itself wasn’t until 1913. (So despite actually occurring on Friday, October 13, 1307, the popular notion that the Friday the 13th stigma comes from the date on which the famed order of the Knights Templar were wiped out by King Philip of France is just a coincidence.)

The repercussions of these phobias reverberated through American culture, particularly in the 20th century. Most skyscrapers and hotels lack a 13th floor, which specifically comes from the tendency in the early 1900s for buildings in New York City to omit the unlucky number (though the Empire State Building has a 13th floor). Some street addresses also skip from 12 to 14, while airports may skip the 13th gate. Allegedly, the popular Friday the 13th films were so-named just to cash in on this menacing date recognition, not because the filmmakers actually believed the date to be unlucky.

So, is Friday the 13th actually unlucky? Despite centuries of superstitious behavior, it largely seems like psychological mumbo jumbo. One 1993 study seemed to reveal that, statistically speaking, Friday the 13th is unlucky, but the study's authors told LiveScience that though the data was accurate, "the paper was just a bit of fun and not to be taken seriously." Other studies have shown no correlation between things like increased accidents or injuries and Friday the 13th.

And Friday the 13th isn't a big deal in other cultures, which have their own unlucky days: Greeks and Spanish-speaking countries consider Tuesday the 13th to be the unluckiest day, while Italians steer clear of Friday the 17th. So today, try to rest a little easy—Friday the 13th may not be so unlucky after all.
