8 tactics grocery stores use to shape your choices

Arvyn Braich — Sun, 02 Nov 2025 17:49:58 +0000

You’re not the one calling the shots in the grocery store. Behind the shelves & signs is a system steering every single one of your choices, whether it’s the snacks you get or the route you take. Here are eight tactics grocery stores use to shape your choices. Which one have you actually seen in real life?

Bigger carts quietly nudge bigger hauls

You may have noticed that carts seem absolutely huge now, and that’s not by accident. When the basket’s deeper, your brain changes what it sees as “normal.” This means that throwing in a few extra boxes or items doesn’t feel like much. And once you add cushy handles & smooth wheels, suddenly, a half-full cart looks rather empty.

Right-hand paths and the racetrack route

Most stores are designed like a loop where you end up walking it clockwise. The perimeter has milk, eggs, bread & produce, all the stuff you actually came for, but between those staples are some strategic detours. A well-placed display or sign right on that loop will pull you into aisles you didn’t plan to visit. But the grocery store wanted you to.

Slow background music changes your pace

The playlist isn’t there for ambiance. When the music goes a little slower, you do as well, and you’ll spend more time wandering with slower steps. Somehow, you end up browsing things you normally breeze past. Fast music has the opposite effect. As such, grocery stores rarely use this kind of music.

Shelf facings and top shelves boost attention

The way products are lined up matters way more than people think. For example, a cereal box with four facings is more likely to catch people’s eyes than one crammed in the corner. The top shelves are also prime territory because your eyes naturally land there first, so brands fight hard for that real estate.

Endcaps at the back pull you into aisles

Sure, the flashy endcaps up front are obvious, but the really powerful ones are the ones at the back. Those displays sit at the end of quieter aisles to pull people in. Whenever you walk by, you’ll see a glimpse of chips or new coffee flavors, which will encourage you to go down an aisle you weren’t planning to enter.

Ambient scents & front-of-store aromas

The first few steps into a grocery store usually smell much better than they have any right to. And it’s not just luck. Grocery stores deliberately place bakeries & coffee stations, even flowers, right near the entrance because the smell hits you quickly. It wakes up your appetite and puts your brain in “buying” mode before you’ve got a cart.

Lighting changes depending on the section

You should pay attention to the lights in the grocery store because they’re not the same everywhere. In the produce section, there’s bright, crisp lighting so everything looks extra fresh, while in wine or specialty sections, the lighting softens a bit so people slow down. Packaged aisles usually sit somewhere between the two.

Eye-catching floor patterns slow you down

The flooring may not seem like it’d matter, yet it does. Some sections have tiles that suddenly get smaller or have busier patterns, which makes you naturally ease up your pace. In that extra moment when you stop, those nearby displays get a better shot at grabbing your attention. It’s quite smart.

How 10 U.S. presidents kept themselves fit

Radha Perera — Sat, 01 Nov 2025 23:49:45 +0000

Being president is hardly a relaxing desk job. And to deal with that stress, many former presidents had some special routines that kept themselves fit & were a regular part of their days. Here’s how ten American presidents kept themselves fit. Which of these routines would fit into your life?

George Washington’s foxhunting miles on horseback

Before most people were even awake, George Washington was on horseback chasing foxes across uneven Virginia fields. He’d go on long rides with hounds over mud & hills. In his journals, Washington described these hunts happening constantly, sometimes for hours, and it wasn’t casual, either. Riding like that took a lot of core & leg strength.

Thomas Jefferson’s daily exercise rule

Thomas Jefferson treated movement as something he couldn’t skip. He pushed his family to block time out every single day, usually for long walks or horseback rides, and he also suggested target practice as a good way to stay active. For him, exercise was a part of the schedule.

John Quincy Adams’s Potomac swims at daybreak

John Quincy Adams had a rather specific routine that involved walking a couple of miles from his place and swimming across the Potomac River. He’d then walk back home like it was nothing. And it didn’t even matter how the weather was because he always did it before breakfast, rain or shine.

Franklin D. Roosevelt’s therapeutic swimming at Warm Springs

But Adams wasn’t the only one who liked to swim. Franklin D. Roosevelt liked going to the warm pools in Warm Springs, Georgia, to exercise after polio, and he’d spend hours in the water doing therapy sessions. He also swam laps. In fact, Roosevelt made the trip rather often and made it a regular part of his physical routine.

Theodore Roosevelt’s jiu-jitsu lessons in the White House

For Theodore Roosevelt, jogging around or doing light stretches wasn’t enough. No, he invited a Japanese judo master, Yoshiaki Yamashita, to teach him jiu-jitsu right inside the White House, and he also paid for lessons for a few friends. Roosevelt learned throws & holds in the East Room.

Herbert Hoover’s morning “Hooverball”

Hooverball was a game that, unsurprisingly, Herbert Hoover played. It worked like volleyball, except the ball was a heavy medicine ball that he & his friends would throw on the South Lawn. They’d toss it back & forth over a net, and keep score like any pickup game. Sure, it sounds odd, but it was intense cardio that kept him in shape.

Harry S. Truman’s fast morning walks

Of course, not every president relied on doing strange fitness routines. Harry S. Truman went for a fast morning walk that often had his bodyguards trailing behind, trying not to lose pace. He clocked about 120 steps per minute according to the reporters who timed him. Truman kept these walks up daily, often for a few miles around D.C.

Dwight D. Eisenhower’s golf habit

Dwight D. Eisenhower loved golf long before he putted on the White House lawn, but it became part of his recovery after he had a heart attack in 1955. Doctors encouraged him to do steady, moderate movement. Golf fit the bill. Eisenhower also had the South Lawn fitted with a putting green so he didn’t have to leave to play.

Barack Obama’s pickup hoops and a full-court upgrade

Basketball was Obama’s favorite sport. Rather than squeezing in gym time, he’d just call up staff or friends & run pickup games on the White House grounds, later converting the old tennis court into a full basketball court. He took the game rather seriously & it apparently was one of his favorite ways to keep fit.

Richard Nixon’s late-night bowling sessions

Richard Nixon didn’t stick to daytime exercise, as he bowled at night, usually downstairs in the single-lane alley beneath the North Portico. Sometimes he’d bring a few people along, other times, he played alone. It actually became a regular thing for him. And it was especially important during long stretches at the White House since it gave him a break.

Research Says Your Washing Machine Can Make You Sick — Here’s How

Hasthi Wand — Mon, 27 Oct 2025 15:29:51 +0000

You might think that your washing machine is one of the cleanest places in your home. Unfortunately not. Yes, it’s full of hot water & detergent, but there’s likely an entire ecosystem that’s hiding under all that cleanliness. It could even be making you sick. But how exactly? Let’s find out.

The sticky base layer inside many washers

Every washer has a bit of grime that never really leaves. The grime eventually becomes a film that’s slimy & sticky, which is perfect for bacteria to take hold. It forms on plastic parts and hoses, as well as rubber seals, becoming a glue trap for microbes.

They thrive off leftover detergent and fabric softener. Worst of all, the microbes will continue surviving after each rinse.

Where microbes tend to hide in a machine

Pull open your detergent drawer and look inside. You may notice some grayish gunk around the edge. It’s where most microbes live because it’s moist, and they also enjoy staying in the drawer & door seal.

These areas stay damp between cycles, while any leftover water gives the germs a place to multiply.

A washer linked to infant colonization

A study in Germany once researched the dangers of washing machines. They found that several newborns were carrying a rare & drug-resistant strain of bacteria called Klebsiella oxytoca.

The washing machine that cleaned the babies’ clothes was spreading these germs because the bacteria had settled inside the washer’s rubber seal. They spread to every load that went through it. So much for a washing machine “cleaning” your clothes.

Cold and “eco” cycles

Quite a few people use low temperatures or eco settings to save energy. Unfortunately, there’s a catch. Cold water doesn’t kill bacteria, and a 104 °F (40 °C) wash will only remove dirt & smell, not the bacteria lingering on your clothes.

Higher heat cycles of over 140 °F (60 °C) are much better for destroying bacterial colonies.

Viruses in laundry

Viruses work differently from bacteria. Some of them may break down quickly in detergent, while others are able to hold onto your clothes unless the temperature is too high.

You’re best off washing your clothes with a good cleaning agent & at a high temperature. A quick wash? That’s just asking for trouble.

Fungi aren’t rare in washers

You might notice a musty smell whenever you open the washing machine door. It’s usually mold. Fungi like Aspergillus & Cladosporium love damp and dark places. Your washer gives them exactly that.

Fungi are able to grow in the rubber gasket or behind the drawer, since it never quite dries out over there. You’ll need a full cleaning cycle or bleach to rinse them out.

Not all machines are the same inside

Yes, front-load washers are efficient. But the problem is that they tend to trap more moisture because they have airtight doors, leaving behind more dampness & a better chance that germs can grow.

Top-loaders dry out faster between washes. You’ll have to decide which one matters more to you, efficiency or cleanliness.

What we know from controlled fabrics and time-on-textile tests

The fabric you use can also make a difference. Microbes can live for days, sometimes even weeks, on damp cotton & polyester, while others tend to die off on dry fabric.

Leaving wet laundry in a pile is a huge mistake. Essentially, you’re giving them exactly what they need to multiply and cause you more problems.

7 animals known for being the softest on Earth

Hasthi Wand — Mon, 13 Oct 2025 13:36:29 +0000

“Soft” doesn’t necessarily mean cuddly. In terms of animals, scientists measure softness in tiny hair widths & feather barbs, as well as how densely those hairs grow. Here are seven animals known for being the softest on Earth. Which one do you think is the cutest?

Featured Image Credit: Shutterstock.

Sea otter

Scientists counted the hair on sea otters and found that they can have up to 140,000 hairs in a single square centimeter. That’s denser than any other mammal we’ve ever studied. In fact, a sea otter’s underhairs are so fine at 7.6 to 11.9 microns across that water can’t touch their skin. One micron is around 0.00003937 inches, so those hairs are rather small.

Platypus

Yes, a platypus looks odd, but its coat is rather impressive. Each square millimeter carries 600 to 900 hairs & traps a layer of air that keeps it warm while it dives. That’s roughly 60,000 to 90,000 hairs per square centimeter. It’s quite important, as they need to stay underwater for long periods without losing body heat.

Vicuña

You probably haven’t heard of the vicuña. It’s a wild relative of the llama & it has fibers so fine they average only 12 to 13 microns wide. Interestingly, research has shown that these animals have incredible uniformity across herds in Peru & Chile, with each staple of fleece being about 31 mm long. This gives their fiber its smooth, almost silk-like look.

Musk ox

Beneath a musk ox’s shaggy coat, they have something called a qiviut, which is an underwool that insulates the animal against Arctic winters. Qiviut fibers are only 17.5–18.2 microns thick on average & researchers discovered that females usually have slightly finer samples than males. That’s quite different from their coarse guard hairs, which can be ten times as thick.

Angora rabbit

Breeders & textile researchers measured the fibers of the Angora rabbit and found that it’s usually between 12.4 and 14.1 microns. So what’s the secret to their softness? Well, the size is just as important as the structure because the down fibers have little to no medulla, which is the central core in hair. This makes the fur flexible & springy.

Cashmere goat

Cashmere goats produce an undercoat that’s between 15.6 and 19.5 microns in diameter. However, some breeds, especially in Inner Mongolia, can go as low as 13.8 microns. The sex & age can affect the hair’s diameter, and so can the climate. But the cashmere itself is hidden under a rougher outer coat. These animals shed it naturally each spring.

Common eider

In northern communities, eider ducks are famous for their down because it behaves differently from goose or duck down. Each barbule has tiny prongs that hook together & form clusters that cling without stitching. In fact, these clusters spring back into shape and insulate the eider evenly, so it’s no surprise it’s known as one of nature’s strongest soft materials.

10 interesting facts about the world’s population

Arvyn Braich — Tue, 07 Oct 2025 20:13:07 +0000

People talk about the world like it’s one big number. However, the statistics about population include some interesting details you don’t hear every day. These go beyond simply who’s living where. Here are ten interesting facts about the world’s population. Which of these surprised you most?

The world hit 8 billion on November 15, 2022

Tuesday, November 15th, 2022, was a special date. It was when the UN’s official estimate finally reached over 8 billion people, although they didn’t count heads one by one. This number came from decades of birth & death records blended with census data. It’s more of a symbolic date than a “true” count. But it was still an important moment in history.

India is the most populous country

China had the most people for many years. But in 2023, India pulled ahead, with a gap of around two million people, which sounds small, but it was enough for the UN to call it. India had about 1.428 billion & China slightly less at 1.426 billion. It was a real passing of the crown. And it’s all thanks to the slowing birth rates in China and steady growth in India.

Global births peaked in 2012

More babies were born in 2012 than in any other year so far, at roughly 146 million. That number has decreased slightly since then. Demographers have tracked this figure with fertility rates, but the big picture is that the world’s “baby boom” year already came & went. Who knows when the next one will happen?

The growth rate fell below 1%

2020 sure was a record-breaking year. It was the first time since the 1950s that the global growth rate slipped under 1% a year. The headcount did rise afterwards, but it’s climbing more slowly than before. Fewer than one extra person per hundred has been added each year worldwide.

Eight countries drive over half of growth

Population growth isn’t spread evenly. According to the UN, just eight countries will account for more than half the world’s increase through 2050. These are Congo (DRC), Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines & Tanzania. The majority of other countries? They’re suffering from low birth rates.

Urban living will reach about 68% by 2050

Anyone who lives in a city will know how packed they feel now. But try imagining nearly 7 out of 10 people worldwide living in one. That’s the UN’s forecast for 2050, and in 2018, the number was closer to 55%. They used data from tracking settlements & standardizing to create this figure. Let’s hope it doesn’t get that bad.

Older adults surpassed under-fives in 2018

In 2018, the worldwide demographic flipped. The number of people aged 65+ outnumbered kids under five for the very first time in history. Looking forward, the UN projects that about one in six people will be 65 or older by 2050. This figure means that the age pyramid will look more like a rectangle in the future.

Japan has the highest share of people over 65

Almost three out of every ten people are now over 65 in Japan. That’s roughly 29% of the population in 2023. It’s a higher figure than anywhere else in the world, even in countries like Italy & Finland. These also have large older populations. But Japan has a high number of older people, yet also a low number of young people.

38% of people live close to coasts

A huge chunk of the world prefers to stay near the water. One 2018 study showed that about 38% of people live within 100 kilometers of a coast, for one reason or another. That’s nearly four out of every ten humans choosing spots that aren’t far from shorelines. It makes sense, though. Coastal zones often mean easier access to trade, food & transportation.

The world will have 43 megacities by 2030

A megacity is defined as 10 million people or more. And the UN expects there will be 43 of them by 2030, although back in 2018, there were only 33. The biggest growth is happening in Asia & Africa. Urban areas are expanding there faster than anywhere else, with cities like Lagos & Kinshasa being on track to join or climb higher on the list.

7 extraordinary animal abilities

Arvyn Braich — Sun, 05 Oct 2025 08:30:52 +0000

Animals are full of surprises. And some of the things they do may sound unbelievable, but they’re real. These include animals with bubble “guns” & little creatures that can shrug off space itself. Here are seven extraordinary animal abilities and the scientific studies behind them (see the end). Which one do you think is the weirdest?

Featured Image Credit: Shutterstock.

The pistol shrimp cavitation snap

A pistol shrimp is able to slam its claw shut, and it’s loud. Pretty loud. In fact, it blasts out a jet of water so fast that it makes a bubble collapse with a bang. That brief implosion is hotter than the surface of the sun & it also gives off a flash of light. It all comes from a shrimp under two inches long.

The peacock mantis shrimp’s punch

The peacock mantis shrimp uses more than simple muscles to punch. It has a biological “spring-loaded hammer,” which is a kind of joint that stores energy. The mantis then lets the punch fly in a move that’s faster than most bullets in water. In fact, high-speed cameras have clocked the strike at over 50 mph. That’s enough to crack crab shells & even aquarium glass.

The electric eel’s shock

An electric eel is essentially an eel with built-in tasers. It fires off rapid electrical pulses that are able to make the fish’s muscles contract without the fish needing to move. The shock freezes prey in place, leaving it utterly helpless, and the eel can use this ability when it’s threatened. The fish can leap up & deliver the jolt straight to whatever’s touching it.

The bombardier beetle’s boiling spray

This beetle has chemistry labs inside its body, and when threatened, it mixes stored chemicals. These instantly react & heat to boiling. The result? A scalding spray that comes out in bursts, almost like a tiny machine gun, with a temperature that reaches near 212°F. The beetle can swivel its nozzle to aim with surprising accuracy.

The wood frog’s deep freeze survival

Wood frogs do what sounds impossible every winter. They literally freeze. Their hearts stop & ice fills much of their bodies, but they aren’t dead. This is because of the amount of glucose & urea that they pump into their cells. It acts like natural antifreeze. Once the warmth of spring arrives, they thaw out and hop off as if nothing happened.

The hagfish’s rapid fiber-gel

The hagfish is a fish that defends itself with instant slime. Yes, really. It releases threads & mucus that mix with seawater to form a gooey net in seconds. The creature expands so much that it can choke the gills of predators trying to bite it, although that’s not the weirdest part. It’s the fact that it takes very little raw material to make gallons of the stuff.

The immortal jellyfish’s lifespan

Scientists found that Turritopsis dohrnii doesn’t age like other animals. Anytime something bad happens, like injury or stress, these jellyfish can literally de-age themselves. They roll back into their polyp stage. Essentially, they start fresh instead of breaking down with age, and they can do it again & again.

6 everyday items from colonial America you may not know

Hasthi Wand — Sun, 14 Sep 2025 15:23:34 +0000

Colonial life involved a lot of clever stuff that was part of early Americans’ ordinary routines. Sure, some of it sounds strange now, but those gadgets made daily chores a lot easier for them. Here are six everyday items from that time that you may not know about. Which of these would you like to have in your home?

Featured Image Credit: Shutterstock.

Bed key for tightening rope beds

Sleeping used to be a lot harder than simply throwing some sheets on because their beds were made with a lattice of ropes pulled through the frame. Over time, those ropes would start to sag, like an old hammock. That’s where a bed key came in handy. Essentially, it was a chunky wooden handle that twisted the ropes tight again & gave the bed a good cranking.

Sugar nippers for breaking a loaf

Sugar packets didn’t exist in colonial America. Instead, sugar came in heavy cone-shaped loaves, almost like solid bricks, and families kept a pair of iron sugar nippers to snap off chunks of it. These nippers were like strong little pincers. While some people chipped the loaf, others used the tool to squeeze it, then they’d crush the bits into finer grains if needed.

Betty lamp for grease-fed lighting

A betty lamp is an open flame fed by animal fat or fish oil that would be placed in a shallow metal dish. The lamp itself had a spout that looked like a beak. Yes, it was messy and certainly smoky, but it got the job done. Early Americans hung them from hooks & adjusted the cloth wick with a pick. They’d also have to keep the grease topped up so it didn’t sputter out mid-evening.

Pounce pot for drying ink and prepping paper

Sure, today, you can just grab a pen to write. But for colonial Americans, it was a lot harder, as the paper was rough & the ink was slow to dry, which made any mistakes smear quite quickly. Enter the pounce pot. This was a little shaker full of fine powder, like ground cuttlefish bone or resin, that they’d sprinkle over the page. It kept their writing neat without blots.

Niddy-noddy for winding measured skeins

A niddy-noddy wasn’t as weird as it sounds. It was a tool for people who spun their own yarn & needed to measure it somehow, and it was essentially a short stick with two crossbars set at right angles. They would loop the yarn in a repeating pattern and count turns to get an exact skein length. It was also useful for dyeing.

Tin reflector oven for hearth roasting

A tin reflector oven looked like a curved metal box with one side open toward the flames, and it was used for open-fire cooking. The colonists would put the meat on a spit. Then, the shiny interior bounced heat around to roast the food evenly, and the drippings collected in a tray. Someone had to keep turning the spit to keep things cooking right.

Why some American bridges are painted specific colors for psychological reasons

Arvyn Braich — Thu, 11 Sep 2025 23:27:21 +0000

You probably don’t think twice about the color of a bridge when you drive over it. But those paint choices aren’t random. Sometimes, designers pick these colors specifically to make you react a certain way as you pass over. What colors do they choose & why? Let’s find out what’s going on behind those color choices.

Featured Image Credit: Shutterstock.

Cool hues make big steel feel lighter

Some steel bridges are painted pale blue or soft green, although not simply for looks. Those shades make massive structures seem a little less intimidating. In states like Minnesota & Maryland, they use cooler tones when they don’t want the bridge to dominate views of the local area, and doing so keeps things calm.

Blue-green palettes for lower arousal

Bridges near parks or rivers often have blue & green tones because those colors are linked to lower physiological arousal. Essentially, they help people stay steady and focused. You’ll usually see this color near quieter parkways, where the goal is to blend with the surroundings & make driving less stressful. Isn’t that nice?

Palettes account for color-vision deficiencies

A portion of the population sees colors differently, especially reds & greens. This means bridge colors can’t use those contrasts alone. As such, designers often pick orange or other high-visibility hues that are still clear for color-deficient drivers, so that the structure is easy to identify for everyone, no matter the lighting or distance.

Low-sheen finishes cut glare and workload

Unfortunately, glossy paint on bridges will cause glare straight into your eyes, which is especially common when the sun’s low. That’s why many agencies use matte or low-sheen finishes. It’s easier on drivers’ eyes & helps prevent you from squinting when you’re driving toward a brighter area.

Corridor palettes support quick recognition

Some stretches of highway feel cohesive, even when the bridges change. Usually, that’s on purpose. A lot of state agencies pick one color family and stick with it along the same route so that your brain recognizes it automatically after a few trips. You don’t spend extra energy figuring out where you are, making driving far easier.

Yellow–green accents boost peripheral detection

Whenever designers want something to stand out in your side vision, they’ll use yellow–green tones. This specific shade is a sweet spot for how our eyes pick up color during the day, so details pop faster, especially at the edges of your view. You’ll sometimes see it on rails or secondary bits of a bridge.

Specific hues can guide emotional framing during approaches

Also, the colors leading up to a bridge can set the mood before you hit the span. Agencies choose natural tones on the approach, then cooler shades on the main structure itself. Such a switch helps keep the experience familiar instead of jarring. Essentially, they’re trying to keep you focused and comfortable as you roll through.

Why Alaska has highways that end in the middle of nowhere

Arvyn Braich — Mon, 08 Sep 2025 14:11:47 +0000

Some highways just stop in Alaska. There’s no town or border, and sometimes, there’s nothing but trees, which makes it seem like Alaska’s roads follow their own rules. Why on earth are there so many dead ends in this state? Here’s the truth behind what’s going on & why it happens in Alaska.

Featured Image Credit: Shutterstock.

Permafrost and thaw settlement

A large portion of Alaska sits on frozen ground, and that ground doesn’t always stay put. When the ice under the surface melts, the roadbed can slump, and in some areas, engineers don’t even bother trying to build past those unstable sections. It would cost an absolute fortune to keep the pavement from sinking. So they don’t bother.

Ending where the work is

Other stretches of road were never meant for family road trips, such as the Dalton Highway. It wasn’t built to connect towns, but rather, to get people & equipment to the oil fields. This meant that the pavement ended as soon as the pipeline did, as there was no reason for it to continue going.

A canceled bridge

Originally, there was supposed to be a bridge between Ketchikan & Gravina Island, and the state even paved part of the highway for it. But then plans for the bridge were axed. As a result, that perfectly good road goes absolutely nowhere and just stops at the water. It has now become nicknamed the “Road to Nowhere.”

Glacial rivers washed out a highway

Mother Nature has her own way of taking charge, and that’s rather obvious along the Copper River Highway. Floods & shifting channels knocked out several bridges, causing the rest of the highway to become a stranded stretch of pavement. No amount of planning is going to help when a river decides to move locations.

Ferry terminals

The ocean itself does the connecting in Southeast Alaska, as highways there often stop right at a ferry dock. The state tries to avoid building expensive roads through mountains & icefields, and instead, it relies on the Marine Highway ferries to carry vehicles between communities. Only Haines, Skagway & Hyder connect by road to the continent.

Short construction seasons

In Alaska, the building season is very short, and crews must work like crazy during the warm months. Everything then shuts down when winter hits. Any big projects will need to be split into chunks over several years, meaning that a temporary end may actually stick around for a while. Some of the unfinished portions are just waiting for their next piece.

Winter ice roads replace pavement

There are some areas where the seasonal ice roads extend the highway route during the coldest months. Trucks use these frozen paths to reach oil fields & remote camps. Then, when spring arrives, the ice melts, meaning that the highway is suddenly gone until the next deep freeze.

Why the Mississippi River once flowed backward for three days

Radha Perera — Sat, 06 Sep 2025 17:11:23 +0000

During the winter of 1811–1812, people living near the Mississippi River saw something they probably thought they’d never witness. It was the river pushing the wrong way. Yes, rather than flowing south, the current surged north for a short while. What caused it to do this, and could it happen again? That’s what we’re going to find out.

Featured Image Credit: Shutterstock.

The earthquakes that set it off

The trouble started late at night on December 16, 1811, when a huge earthquake hit the New Madrid region of Missouri, shaking an area bigger than most states. Two more followed in January & early February. However, these weren’t small tremors you might sleep through. They were actually so strong that even places far to the east felt them rumble through the ground.

Where on the river it happened

The February quake struck the area from New Madrid up to a bend near Kentucky. That stretch sits right on top of a fault that cuts across the riverbed, with the bend jerking upward in some spots & dropping in others. Such a sudden shift happened exactly where the river flowed. As such, the water reacted in a rather dramatic way.

What can make a great river run upstream

Earthquakes can throw big chunks of land upward in just a few seconds. When that happens under a river, the water slams into the new “wall” of land, and in the case of the Mississippi, parts of the riverbed went up so quickly that the current reversed. There were also powerful wave surges that raced back upstream.

How long the upstream surge lasted

The old reports talk about the river “running backward.” However, they don’t mean it flipped directions for days on end, as the backward flow only lasted a little while each time the quakes hit. It didn’t reverse continuously for three days. Rather, the region shook over & over for months, so different towns experienced different moments of the river acting strangely.

Why “three days” became part of the story

So where did the “three days” idea come from? It’s because people told & retold the story over time, with those separate events eventually sounding like one big, drawn-out episode. Yes, it flowed backwards, but it was for a short while, and not three days straight.

What else changed on and around the river

However, the quakes messed with more than the water’s direction. They also changed the landscape, as fault movement created sudden drops in the ground, which trapped streams. This turned parts of northwest Tennessee into what became Reelfoot Lake. Riverbanks also slumped into the water, and some areas along the river even had temporary waterfalls.

How researchers pieced it together

Nobody had seismographs back then, and it took a while for scientists to figure out what happened. It was only years later that they managed to use geological evidence & reports to trace where the faults run under the river. They then matched these with descriptions from people who lived through the shaking.
