The horse diaper

Designed to catch manure in crowded cities—a problem once so severe that it shaped public infrastructure as well as the entrances to houses—the horse diaper was an invention meant to be strapped beneath working horses pulling carts and carriages.

The idea was to reduce disease and street filth during the horse-powered urban era. While the device saw limited use before automobiles rapidly replaced horses, similar designs are still occasionally used in modern veterinary practice.

The baby cage

Built as wire cages attached to apartment windows, so-called "baby cages" allowed infants to get fresh air when outdoor space was unavailable. Some models were guaranteed to safely hold over 30 pounds.

While alarming today and ultimately abandoned due to obvious safety concerns, the designs likely inspired some of the baby-proofing nets used today.

The pneumatic subway

In the late 1860s, American entrepreneur and inventor Alfred Ely Beach set out to prove the feasibility of a human-sized pneumatic subway system beneath New York City, capable of moving both people and cargo using nothing more than air pressure.

The prototype was set up as a public attraction and carried passengers along a tunnel just over 300 feet long, from a station to a dead end. Despite its initial success, bureaucratic obstacles and high costs halted expansion, leaving it as a functional but largely forgotten underground experiment.

The mechanical horse

Image: Gabriel Tovar

Created for exercise and riding practice, the mechanical horse used a system of gears, cranks, and pedals to simulate walking and trotting motions while the rider sat in a saddle-like seat. It was marketed to urban riders and cavalry trainees who lacked access to stables or live horses.

Though bulky and impractical for widespread use, the device anticipated modern fitness machines by replicating real-world movements for conditioning and skill retention, rather than simple repetitive exercise.

The first metal detector

Image: Fer Troulik

After a failed assassination attempt on President James Garfield, Alexander Graham Bell hastily built an early metal detector in an effort to locate the bullet lodged in his body. The device functioned as intended, but it was unable to find the bullet because metal bed springs interfered with the signal.

Despite this setback, Bell’s early design proved the concept and directly influenced the development of modern metal detectors.

The pet-powered butter churn

Image: Matt Bero

In an inventive twist on animal-powered machinery, some 19th-century American farmers rigged small treadwheels for dogs, cats, or even goats to generate kinetic energy for churning butter. The animal ran inside the wheel, turning a rope or pulley connected to the churn.

While technically functional, the system was limited by the animal's willingness to cooperate and the small amount of power it generated.

The umbrella hat

Image: Claudio Schwarz

Robert W. Patten, often called the "Umbrella Man," patented one of the first commercially successful hands-free umbrella hats. It strapped a small umbrella directly to the wearer’s head, providing both sun and rain protection while keeping the hands free for work or walking.

His original design even included a mosquito net attached to the canopy. Patten didn’t enjoy much commercial success but became somewhat of an eccentric and comical popular figure, partly due to a series of comics that were inspired by his unusual invention.

The one-wheel motorcycle

Image: CJ Toscano

In 1971, American inventor Kerry McLean built and refined a monowheel—a one‑wheeled motorized vehicle in which the rider and engine sit inside the wheel’s circumference.

Since then, various attempts have been made to build on his original design, but it remains a niche vehicle used primarily for entertainment rather than practicality, as riders must be highly skilled simply to turn or even stay upright.

The first talking doll

Image: Holly Ward

In 1890, Thomas Edison embedded miniature versions of one of his most popular inventions —the phonograph—inside dolls so they could recite nursery rhymes.

While the idea was innovative, the technology was not yet there. The recordings were fragile, distorted, and often failed to work properly. The dolls were pulled from the market within weeks due to customer complaints, making it one of Edison’s rare commercial failures.

The glass harmonica

Image: Francesco Bovolin

Faithful to his eccentricity and inventive spirit, Benjamin Franklin redesigned the existing glass harp into a rotating spindle of glass bowls, played by touching the spinning rims with wet fingers, which he called the "glass harmonica."

The instrument produced eerie, sustained tones unlike anything else of its era. However, its fragile nature made it somewhat impractical, and the rotating mechanism posed a potential danger to the player if anything went wrong.

George Washington had wooden teeth

Image: Todd Trapani

Washington suffered from dental problems throughout his adult life and did wear several sets of false teeth. However, he did not wear wooden ones.

They were made from materials like ivory, metal, and springs . The "wood" myth probably comes from the staining of ivory and from 19th-century caricatures.

2

Salem witches were burned at the stake

Image: Sofia Holmberg

We hold the long-standing belief that the accused Salem "witches" were burned like European witch victims.

However, in the Salem (and colonial New England) trials of 1692–1693, convicted witches were almost always executed by hanging ; burning at the stake was not the legal penalty under English law in the colonies.

Paul Revere rode and shouted, "The British are coming!" alone

Image: Mikhaël Noury

He may be riding alone in the Boston statue that represents the dramatic midnight ride in which he warned of the British troop movements.

But in reality, Revere was one of several riders who spread word of the British troop movements; Longfellow’s 1860 poem amplified and simplified the story, including the shouted line, which would have been unlikely among colonists.

4

Betsy Ross designed the first American flag

Image: Heather Newsom

We have heard again and again the myth that Betsy Ross stitched the first Stars and Stripes after being asked by George Washington. In reality, this tale grew from a family tradition promoted more than a century after 1776. Historians have found no contemporary documentation proving that she designed the first official flag.

The flag’s creation was likely more complex and collective. Ross has always remained a folk symbol, but there is no proof that she was the sole designer.

Mrs. O’Leary’s cow started the Great Chicago Fire

Image: raquel raq

The myth: a cow kicked over a lantern in Catherine O’Leary’s barn and caused the 1871 conflagration. The cow story originated in sensational newspaper reporting and later became part of folklore.

Investigations have never produced conclusive proof, and modern historians treat the O’Leary–cow tale as an unfair scapegoating and probably apocryphal. The fire’s precise origin remains a mystery.

"Molly Pitcher" was a famous woman who operated a cannon at Monmouth

Image: Foysal Razu

The story of Molly Pitcher, a single heroic woman who supposedly took over a cannon when her husband fell, may have been created to represent several women . The best documented candidate is Mary Ludwig Hays, but the legend also reflects the broader contributions of women who supported troops during the Revolutionary War, with or without having been widowed.

Davy Crockett died fighting to the last at the Alamo

Image: Eric Francis

Did Crockett heroically fight to the death amid hand-to-hand combat at the Alamo? Well, that was indeed the location of his death, but sources conflict about the manner.

Some eyewitness accounts and Mexican records suggest he may have been captured and executed; other accounts describe him dying in combat. The neat heroic portrait was shaped by 19th-century myth-making.

The Declaration of Independence was signed on July 4, 1776

Image: The New York Public Library

It is widely believed that all signers of the Declaration of Independence scribbled their names on it on July 4, which is why we celebrate that date.

Congress adopted the Declaration on July 4, but most delegates did not sign the parchment copy until August 2 of that year (and a few added their names even later). July 4 became the commemorative date for adoption and celebration, not the universal signing day.

The Pilgrims’ "First Thanksgiving" centered on a big roast turkey, like today

Image: Tyler Donaghy

No, the 1621 harvest meal at Plymouth did not feature the same turkey-centered feast we picture now.

Accounts mention venison and wildfowl, but the menu and ritual context were very different from modern Thanksgiving dinners. The idea of an annualized, turkey-centered national holiday developed much later (19th century onward).

Thomas Edison single-handedly invented the light bulb

Image: Tamas Pap

Many believe that Edison alone invented the incandescent light bulb out of whole cloth. But electric light was the product of decades of work by many inventors (from Humphry Davy to Swan and others).

Edison’s contribution was significant improvements and the critical development of a commercially viable, manufacturable system, but he did not "invent" electric light in isolation.

11

Pocahontas dramatically saved John Smith from execution

Image: EricThriller

The myth holds that Pocahontas heroically rescued Captain John Smith by throwing herself over him at the moment of execution.

Disney may have amplified the romantic and dramatic aspects of this story. John Smith’s account of a dramatic rescue appears in later writings and is debated by historians. Many scholars now interpret the scene as a ritual adoption or a ceremonial act rather than a literal rescue, or they suspect Smith embellished the story.

Most Big Mac burgers eaten in a lifetime

Image: amirali mirhashemian

Sure, we all enjoy a delicious burger every now and then, but 34,000? That's the total number of Big Macs a 70-year-old retired prison officer from Fond du Lac, Wisconsin, has consumed in his lifetime. Recently, after eating 728 more burgers throughout 2023, Donald Gorske has extended his world record.

On May 17, 1972, Gorske had his first Big Mac and from then on, he never stopped. Every day, he skips breakfast and goes straight for one burger at lunch and one at dinner, accompanied by fries or fruit. Gorske said he used to drive to McDonald's every day, but since retiring, he buys the burgers twice a week in batches and then heats them up in the microwave. What about you? If you had to choose just one food to eat for the rest of your life, what would it be?

Farthest distance to blow a pea

Image: Elena Leya

Some use the power of their lungs to run marathons, while others use it to break curious world records. On October 8, 2022, David Rush set out to accomplish a feat that, while unusual, required great precision and breathing control: the greatest distance traveled by a blown pea.

With a mixture of concentration and dexterity, Rush managed to blow a single green pea an impressive 84 feet, 11 inches. What makes this record even more remarkable is that he achieved this distance with a single breath. This accomplishment is just one more in the extensive list of Guinness World Records that the Boise, Idaho, resident has achieved in his lifetime; in fact, in August 2024, Rush became the world's top record breaker with 181 titles.

Largest collection of teddy bears

Image: MirelaSchenk

Not long ago, an American woman named Jackie Miley held the title for the largest collection of teddy bears. In her home in Rapid City, South Dakota, Jackie zealously guarded more than 8,000 teddy bears. The collection consisted of at least one bear representing each of the U.S. states and 29 different countries. She got her first bear during a vacation in 2000, and it wasn't until she reached 3,000 bears that she contacted Guinness World Records.

Unfortunately for Jackie, her record was beaten in 2019 by a Hungarian woman named Istvánné Arnóczki, who owns a total of 20,367 teddy bears. However, as far as stuffed animals go, the United States remains on the podium. In 2024, a 27-year-old from Mascoutah, Illinois, entered the Guinness World Records for having an impressive collection of 1,523 Squishmallows, a brand of stuffed toy launched in 2017 that boasts 3,000 different styles.

Longest birthday

Image: jarmoluk

Many of us wish our birthdays lasted a little longer than just 24 hours. Well, one young Hawaii native made that dream come true. On February 3, 2018, Paul Morgan celebrated his 28th birthday in a totally original way: by making it the longest birthday ever recorded. But how did he do it? He simply took advantage of the difference in time zones around the world! In doing so, he extended his special day to a total of 48 hours, breaking the Guinness World Record for the longest birthday in history.

Morgan began his epic celebration in Apia, Samoa, one of the first places in the world to welcome each new day. From there, he flew to Auckland, New Zealand, before heading to Los Angeles, and finally landing in Kauai, Hawaii. This carefully planned trip allowed him to cross several time zones and extend his birthday to twice as long as normal. Clever, huh?

Most candles on a cake

Image: Tim Cooper

And if we talk about birthdays, we can't miss cake! As we get older, candles multiply, but you'll never guess what the largest number of candles on a cake ever recorded is. In 2016, members of the Sri Chinmoy Center in New York, an Eastern philosophy spiritual group, achieved the world record for the most candles lit on a birthday cake.

They burned 72,585 candles for 40 seconds on a huge cake measuring 80.5 feet long and 2 feet wide. It took 100 volunteers to light them and a couple of fire extinguishers to put them out safely. We are not sure if the attendees were able to eat the delicious vanilla mousse sponge cake after such a blaze, but the video of the feat can be seen on YouTube. As of today, it has already been viewed by more than 220,000 people!

Most tricks performed by a cow in one minute

Image: leppäkerttu

It's not just humans who break world records, animals do too! In March 2023, a four-year-old Charolais cow named Ghost broke a Guinness World Record by performing 10 tricks in just one minute. This record, which might seem more fitting for a dog or a horse, is the sole merit of her owner’s ingenuity, Nebraskan Megan Reimann, who applied horse training techniques, such as positive reinforcement, to teach her a series of amazing skills.

Among Ghost’s incredible talents are her ability to come when called, turn, nod her head, give kisses, and even bow—all in just 60 seconds. The success of the "world's smartest cow" is not only a testament to her intelligence but also to the potential all animals have to learn and perform exceptional feats.

Highest number counted out loud

Image: Mishelved

This Guinness World Record is probably the exact opposite of counting sheep to sleep. In the summer of 2007, a resident of Birmingham, Alabama, named Jeremy Harper embarked on a feat that would test both his physical and mental endurance: counting out loud to the number one million without leaving his apartment.

For four months in a row, Harper live-streamed his quest on YouTube, capturing an audience of thousands around the world who tuned in to watch him recite more than 11,000 numbers a day. After 89 long days without breaks, sunlight, or privacy, Harper finally reached his goal and set the Guinness World Record for the highest number ever counted out loud.

Most bobby pins in a beard

Surely, when San Francisco-based cosmetics manufacturer Luis Marcus invented bobby pins in the early 20th century, he never imagined that a hundred years later they would be part of a world record. On July 21, 2021, Dean Banowetz, a California hairstylist, set out to accomplish a feat few would have imagined: placing the most bobby pins in a beard.

With precision and dedication, Banowetz managed to attach a total of 4,831 bobby pins to his own beard, surpassing all expectations and setting a unique world record. This stylist, who was already known as the Hollywood Hair Guy, proved that his skill goes beyond traditional hairdressing techniques, exploring the creative potential of something as simple as a bobby pin.

Heaviest kale

Image: Monika Borys

If humans and animals can break world records, why can't the vegetable world do it too? In August 2007, Scott Robb, a horticulturist from Palmer, Alaska, presented a kale at the State Fair that left everyone open-mouthed with its colossal size: 105 pounds, 14.5 ounces.

This achievement was no fluke but the result of years of perfecting farming techniques and a passion for growing giant vegetables. Robb is no stranger to the world of horticultural records; he also holds titles for growing the heaviest turnip (39.2 pounds), the heaviest kohlrabi (nearly 97 pounds), and the heaviest green cabbage (138.25 pounds). Robb's dedication has made Palmer, Alaska, a benchmark for gardening enthusiasts and Guinness World Records.

Largest hands and feet on a living teenager

Image: KlausHausmann

Eric Kilburn Jr., a 16-year-old from Michigan, has stamped his footprint in the 2025 Guinness World Records book—literally! With feet measuring 13.50 inches and hands just over 7.4 inches, Eric holds the title of "largest hands and feet on a teenager".

His shoe size is an impressive 23 American , while the average for an adult male typically ranges from 8.5 to 9. Before he rose to fame, his mother faced challenges having to get shoes custom-made for him; they cost more than US$ 1,500 a pair. Fortunately, after Eric’s story went viral, brands like Puma and Under Armour offered him custom shoes.
