What Makes Tumbleweeds Tumble?

While most plants benefit from a sedentary lifestyle, a single tumbleweed can roll for miles across open terrain. In the video below, The Kid Should See This explains what makes these unusual weeds the lone wanderers of the West.

Think of a tumbleweed and you'll likely picture a plant that's already dead. The live version of a tumbleweed is called a Russian thistle. Like many other plants, it flowers and dies over the course of a season, but instead of relying on animals to disperse its seeds, it breaks off from its roots and plants the next generation itself. The wind carries the dried-out bush across barren landscapes where new seedlings can flourish without competition from grasses and other plants. As the weed bounces along, tiny seeds packed with coiled-up embryos sprinkle out from between its thorny leaves.

Though tumbleweeds may be an iconic symbol of the Wild West, they originated in Eastern Europe. They likely arrived as stowaways in shipments of flax seeds brought to the U.S. in the 19th century.

Some people living out west today aren't too fond of the European import. The California town of Victorville was recently invaded by tumbleweeds when wind gusts approaching 50 mph blew in from the Mojave Desert. In some cases the tumbleweeds clustered on doorsteps, trapping residents inside their homes.

How and Why Did Silent Letters Emerge in English?

Kory Stamper:

The easy answer is “"because English can’t leave well enough alone."

When we first started speaking English around 600 AD, it was totally phonetic: every letter had a sound, and we sounded every letter in a word. But English—and England itself—were influenced quite a bit by the French, who conquered the island in 1066 and held it for a long time. And then later by Dutch and Flemish printers, who were basically the main publishers in England for a solid two centuries, and then by further trading contact with just about every continent on the planet. And while we’re shaking hands and stealing language from every single people-group we meet, different parts of the language started changing at uneven rates.

By the 1400s, English started to lose its phonetic-ness: the way we articulated vowels in words like “loud” changed slowly but dramatically, and that had an effect on the rest of the word. (This is called “The Great Vowel Shift,” and it took place over a few hundred years.) Somewhere in the middle of the GVS, though, English spelling became fixed primarily because of the printing press and the easy distribution/availability of printed materials. In short: we have silent letters because the spelling of words stopped changing to match their pronunciations.

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.
