10 Everyday Objects That Were Originally Meant for Something Else
Some inventions are the result of genius. Others? Pure accident, miscalculation, or downright desperation. But perhaps the most fascinating ones are those that started with one purpose… and ended up somewhere completely different. From household staples to things you carry in your pocket right now, here are ten everyday objects that weren’t supposed to be what they are today—and the stories behind their surprising origins.
1. Listerine: From Floor Cleaner to Mouthwash
Before it became the go-to solution for bad breath, Listerine had a long résumé of odd jobs. Invented in 1879 by Dr. Joseph Lawrence, it was initially marketed as a powerful surgical antiseptic, thanks to its ability to kill bacteria and prevent infections during operations. But Lawrence and his partner Jordan Lambert didn’t stop there—they pitched it as a disinfectant for floors, a treatment for dandruff, and even as a cure for gonorrhea. It was like the Swiss Army knife of the hygiene world.
Its big break came in the 1920s, not because it changed, but because its marketing did. The company coined the term halitosis—a medical-sounding word to describe bad breath, which until then was simply a minor embarrassment, not a socially isolating condition. With this clever bit of fear-based advertising, Listerine went from selling $100,000 a year to over $4 million in just a few years. The product hadn’t changed—only how people thought about their mouths had.

2. Bubble Wrap: Intended as Wallpaper
In the 1950s, inventors Alfred Fielding and Marc Chavannes were chasing a design dream: they wanted to create a textured, fashion-forward wallpaper by fusing two plastic shower curtains together. The result was... bumpy. It didn’t catch on as home decor—surprising no one in hindsight. But their failed invention had something else going for it: cushioning power.
The two didn’t give up. At first, they tried to sell it as greenhouse insulation. That too fizzled. Finally, IBM came calling. They needed a way to safely ship their delicate new computers, and Bubble Wrap was the perfect fit. It was light, protective, and fun to pop. That last part turned out to be a happy accident, too—its satisfying “pop” has made it one of the most beloved packaging materials in history. There’s even a Bubble Wrap Appreciation Day celebrated every January!

3. Coca-Cola: A Nerve Tonic for Addicts
In 1886, John Pemberton, a pharmacist and wounded Civil War veteran, was desperate for a cure for his morphine addiction. His solution? A tonic made with coca leaf extract (yes, actual cocaine) and kola nut caffeine—a pick-me-up he called Pemberton’s French Wine Coca. When prohibition laws hit Atlanta, he reformulated it without alcohol and renamed it Coca-Cola.
Though it started as a patent medicine, it quickly transitioned into a refreshing drink, thanks largely to clever marketing and word-of-mouth. By the early 20th century, Coca-Cola was being sold at soda fountains as a kind of “temperance drink.” The cocaine was removed from the formula by 1929—but the brand’s addictive appeal had already taken root.
Fun fact: Coca-Cola is still made with coca leaves, but they're decocainized by a single licensed company in New Jersey. That’s right—there’s still a bit of the old drugstore tonic in every bottle, minus the high.

4. Play-Doh: Wallpaper Cleaner for Sooty Homes
Long before kids rolled it into meatballs and monsters, Play-Doh served a much dustier purpose. In the 1930s, Kutol Products, a struggling soap company in Cincinnati, developed a compound designed to clean coal soot from wallpaper. Back then, most homes were heated with coal furnaces, which left behind a fine layer of dark grime. The cleaner was a soft, non-toxic putty that could be gently rubbed on walls without damaging the paper.
But as the 1950s rolled in, so did natural gas heating, which meant cleaner homes—and no more soot. The product was on its way to extinction until a schoolteacher named Kay Zufall had an idea. She had used the cleaner in her classroom and noticed how much kids loved playing with it. She suggested marketing it as a children’s toy.
Kutol rebranded it as Play-Doh, added color and scent, and launched it in toy stores. It became an instant hit. Within a decade, millions of cans had been sold. The cleaner that nearly vanished from the shelves is now a childhood staple found in nearly every classroom and playroom across the globe.
5. WD-40: Meant to Protect Missiles
The “WD” in WD-40 stands for Water Displacement, and the "40" marks the number of attempts it took to get the formula just right. It was invented in 1953 by a small company called Rocket Chemical Company, specifically to protect the outer skin of Atlas missiles from rust and corrosion. Yes, that blue-and-yellow can in your garage started out as military tech.
The product worked so well that workers at the company began sneaking it home to fix squeaky hinges and loosen stuck bolts. When management found out, instead of cracking down, they leaned into it. WD-40 was put on shelves for consumer use in 1958—and it took off like a rocket (pun intended).
Today, it’s used for everything from removing crayon marks from walls to freeing zippers and loosening bicycle chains. It’s even been sprayed on fishing lures to mask human scent. With over 2,000 documented uses (and counting), this rust-prevention formula turned household MVP might be the most versatile accident in your toolbox.

6. Tissues: Designed for Gas Masks
Kleenex tissues weren’t made for colds or makeup at first—they were born on the battlefield. During World War I, Kimberly-Clark created a new absorbent material called cellucotton, five times more absorbent than cotton, and used it to line gas mask filters for soldiers. After the war ended, the company had a surplus of the stuff and needed to repurpose it fast.
In the 1920s, they introduced it as a disposable alternative to cold cream cloths, marketing it to women as a glamorous beauty aid. But something unexpected happened: consumers began writing in, saying they used the product to blow their noses. Kimberly-Clark didn’t see that coming—but they leaned in, and Kleenex tissues became a staple for sniffles instead of smoky eyeliner.
Today, tissues are synonymous with runny noses and emotional movie nights—but their origin is steeped in war and innovation. Not bad for a product that was never supposed to leave the trenches.
7. Microwave Ovens: A Candy-Melting Accident
Sometimes, genius strikes when your snack melts in your pocket. In 1945, Percy Spencer, an engineer working for Raytheon, was tinkering with magnetrons—the power source for radar systems—when he noticed something odd: the chocolate bar in his pocket had melted. Curious (and maybe a bit sticky), he placed popcorn kernels near the device. They popped. He tried an egg next. It exploded. That’s when he realized microwaves emitted by magnetrons could heat food incredibly fast.
Raytheon rushed to patent the idea, and in 1947, they released the first microwave oven: the Radarange. It was the size of a fridge, cost over $5,000, and needed water cooling. Unsurprisingly, it didn’t sell well. But by the 1970s, miniaturized versions hit the market, and the miracle of reheated leftovers was born.
Today, microwave ovens are nearly universal. They’ve changed how we eat, cook, and think about time. But none of it would’ve happened if Percy hadn’t packed a candy bar that day.
8. Super Glue: A Rejected Weapon Tech
Super Glue was born from wartime research, but its stickiness was too much for its intended use. In 1942, Dr. Harry Coover was working on clear plastic gun sights for WWII firearms. He was testing materials called cyanoacrylates, but they stuck to everything—including lab equipment. He shelved the idea as a failed experiment.
Years later, while working at Eastman Kodak, Coover revisited the compound and realized it wasn’t a failure at all—it was a superior adhesive. In 1958, Super Glue hit the consumer market and quickly became a household essential. But its usefulness didn’t end there.
During the Vietnam War, medics used Super Glue to temporarily seal wounds on the battlefield, buying soldiers time until they could get proper medical attention. Though it was never FDA-approved for internal use, it saved lives and sparked research into modern medical adhesives. Not bad for a lab mistake that almost got thrown away twice.

9. Viagra: A Heart Medication Gone Wild
In the early 1990s, researchers at Pfizer were testing a drug called Sildenafil as a treatment for angina, a type of chest pain caused by reduced blood flow to the heart. But during clinical trials, participants kept reporting an unexpected side effect: increased blood flow somewhere else. And it wasn’t the heart.
Though it failed as a heart drug, Sildenafil’s, ahem, stimulating effect got researchers thinking. They refocused trials on erectile dysfunction, a condition that—until then—had few reliable treatments. In 1998, Viagra was approved by the FDA, becoming a cultural and pharmaceutical phenomenon almost overnight.
Viagra didn’t just revolutionize men’s health; it launched an entirely new category of medication, opened conversations about aging and sexuality, and made Pfizer billions. And it all started with a disappointing heart drug that turned out to have a lot more... potential.

10. Corn Flakes: An Anti-Masturbation Cereal
As bizarre as it sounds, Corn Flakes were invented to fight what Dr. John Harvey Kellogg saw as the root of all evil: sexual desire. Kellogg, a physician and devout Seventh-day Adventist, believed that a bland diet would discourage carnal urges, especially among young men. In the late 19th century, he and his brother Will accidentally flaked some cooked wheat and later corn during a sanitarium experiment—and Corn Flakes were born.
Kellogg preached that spicy, flavorful food was “stimulating,” and therefore dangerous. He lived a celibate life—yes, even with his wife—and advocated for the use of yogurt enemas and mechanical devices to suppress libido. His cereals were part of a broader health crusade based on abstinence and restraint.
Will Kellogg, the more business-minded brother, eventually added sugar to the flakes and started the Kellogg Company, steering the product away from its anti-pleasure roots and toward breakfast-table domination. Ironically, the cereal designed to stifle desire became a sweet, crunchy favorite around the world.
