11 Amazing Things You Didn't Know Were Invented by Kids

It doesn't take decades of life experience to have a great idea. In fact, you don't even have to be old enough to have a driver's license, as many of these young inventors have proven.

1. BRAILLE

Louis Braille suffered a serious eye injury when he was just 3 years old. Not only did the accident render him blind on that side, the infection spread and blinded the other eye as well. After more than a decade of struggling with the slow system of tracing his finger over raised letters, Braille was 12 when he learned of a method of silent communication originally created for the French military. He simplified it, and in 1824 the Braille language was born.

Teenagers continue to revolutionize the Braille system. In 2014, 12-year-old Shubham Banerjee created a Braille printer from a LEGO Mindstorms set. Named the Braigo, the $200 printer is much more affordable and attainable than the $2000 alternative.

2. CHRISTMAS LIGHTS

Before electric lights were invented, many people decorated Christmas trees with actual candles. What could go wrong with open flames attached to dead branches studded with dry, brittle needles, all located inside your home? However, even when electric lights became available, people were more concerned about electricity burning their houses down rather than the candles.

But by 1917, people were more used to electricity and 15-year-old Albert Sadacca was ready to capitalize on their trust. Prior to that time, those brave enough to try electric Christmas tree lights had to shell out approximately $2000 in today's money for the privilege. Sadacca had the idea to create an affordable set of Christmas lights and had them produced by his parents' novelty lighting company. It's because of him that lights are now a ubiquitous part of the holiday season.

3. TRAMPOLINE

As a teenage gymnast, George Nissen and his coach created a "bouncing rig" that helped him generate the power and height to do a back somersault. Originally made out of scrap steel and tire inner tubes, the platform was adapted later into a portable version that he called the "trampoline." Fun fact: In the 1950s, gas stations bought trampolines to use as "jump centers," a way for kids to get a little energy out before getting back in the car with their parents.

4. TOY TRUCKS

In 1962, 5-year-old Robert Patch cobbled together a couple of shoe boxes and some bottle caps to create a vehicle that could transform into three different trucks: a dump truck, a flatbed, and a box truck. His patent attorney father saw potential and applied for a patent in his son’s name. Young Robert Patch signed his name with an "X"—he didn’t know how to spell yet. Though Patch turned 6 by the time the patent was granted, it was still young enough to be the youngest patent holder ever at the time.

5. POPSICLES

A lot of kids are easily distracted—and thanks to the short attention span of 11-year-old Frank Epperson, we now have Popsicles. In 1905, Epperson, a San Francisco native, was stirring powdered drink mix into a cup of water when something else caught his attention. The concoction was forgotten on his porch, and when Epperson rediscovered the drink in the morning, it was a deliciously portable frozen lollipop. After years of making the frozen treats for friends, and eventually his own children, Epperson filed for a patent in 1924.

6. SNOWMOBILE

Quebec native Joseph-Armand Bombardier had always been a tinkerer, and on New Year's Eve in 1922, he surprised his family with his latest creation. He had mounted the engine of a Ford Model T to four runners, with a handmade propeller perched on the back. Steered by Bombardier's younger brother, the contraption traveled more than half a mile across the snow before coming to a stop. The 15-year-old inventor continued perfecting his snowmobile over the years, adding tank-like tracks to it in 1935. By 1959, his tinkering had resulted in the Ski-Doo, the first ultralight snowmobile model.

7. WATER TALKIE

In 1996, fifth-grader Richie Stachowski invented the Water Talkie, a device that allows people to talk to each other underwater. It was a hit, so Stachowski expanded his product line under a company he called Short Stack. The new lineup included the Scuba Scope and the Bumper Jumper Water Pumper. In 1999, at age 13, the pint-sized entrepreneur sold Short Stack to a San Francisco-based toy company for what was speculated to be millions.

8. SUPERMAN

As a teen, Jerry Siegel was having a hard time sleeping one hot summer night in 1934. Restless, his mind turned to his favorite science fiction stories—and as he looked outside at the moon, he got an idea of his own. Siegel jotted them down, and in the morning, ran to visit his artist friend Joe Shuster, who made some sketches. Four years later, they found a publisher, and today, Superman is one of the most recognizable characters in the world.

9. SWIM FLIPPERS

In the early 1700s, an 11-year-old boy who loved to swim noted that he could cut through the water more easily if he had more surface area to push through it with. He fashioned handheld swimming fins out of oval-shaped planks, making holes in the middle for his hands. He made fins for his feet as well, but wasn’t happy with the clunky design and quickly abandoned them.

The fins were just one of the boy’s many inventions—the kid we know today as Ben Franklin grew up to create a stove, the odometer, a lightning rod, and bifocals, among other things. As an adult, his continued love for swimming earned him a spot in the International Swimming Hall of Fame.

10. EARMUFFS

It can get pretty chilly in Maine, so it’s no wonder that they have a day honoring Chester Greenwood, who invented earmuffs in 1873 when he was just 15. Greenwood loved to ice skate on frozen ponds during the cold Maine winters, but a wool allergy kept him from donning the warm hats with earflaps that his friends wore. Tired of having to call it quits due to his cold ears, Greenwood asked his grandmother to sew flaps of flannel or beaver fur onto some wires that he could bend around his head. Ten years later, Greenwood was the owner of an earmuff factory that produced 50,000 of them every year.

By the way, should you want to celebrate Greenwood and his cozy contribution to society, Chester Greenwood Day is the first Saturday in December.

11. MAKIN' BACON

You may remember the Makin' Bacon kitchen gadget from the 1990s; you may even still own one. The microwave rack, which cooks bacon strips perfectly while catching the excess grease in a drip pan, was the brainchild of an 8-year-old girl named Abbey Fleck. Abbey was helping her parents with breakfast one morning when they ran out of paper towels to sop up the grease. After wondering why they couldn't just hang the bacon like laundry and let the extra fat drip off, she and her dad fashioned a successful prototype out of plastic hangers and dowel rods. She has since sold 2.7 million Makin' Bacons through Walmart alone.

15 Riveting Facts About Alan Turing

More than six decades after his death, Alan Turing’s life remains a point of fascination—even for people who have no interest in his groundbreaking work in computer science. He has been the subject of a play and an opera, and referenced in multiple novels and numerous musical albums. The Benedict Cumberbatch film about his life, The Imitation Game, received eight Oscar nominations. But just who was he in real life? Here are 15 facts you should know about Alan Turing, who was born on this day in 1912.

1. HE’S THE FATHER OF MODERN COMPUTER SCIENCE.

Turing essentially pioneered the idea of computer memory. In 1936, Turing published a seminal paper called “On Computable Numbers” [PDF], which The Washington Post has called “the founding document of the computer age.” In the philosophical article, he hypothesized that one day, we could build machines that could compute any problem that a human could, using 0s and 1s. Turing proposed single-task machines called Turing machines that would be capable of solving just one type of math problem, but a “universal computer” would be able to tackle any kind of problem thrown at it by storing instructional code in the computer’s memory. Turing’s ideas about memory storage and using a single machine to carry out all tasks laid the foundation for what would become the digital computer.

In 1945, while working for the UK’s National Physical Laboratory, he came up with the Automatic Computing Machine, the first digital computer with stored programs. Previous computers didn’t have electric memory storage, and had to be manually rewired to switch between different programs.

2. HE PLAYED A HUGE ROLE IN WINNING WORLD WAR II.

Turing began working at Bletchley Park, Britain’s secret headquarters for its codebreakers during World War II, in 1939. By one estimate, his work there may have cut the war short by up to two years. He’s credited with saving millions of lives.

Turing immediately got to work designing a codebreaking machine called the Bombe (an update of a previous Polish machine) with the help of his colleague Gordon Welchman. The Bombe shortened the steps required in decoding, and 200 of them were built for British use over the course of the war. They allowed codebreakers to decipher up to 4000 messages a day.

His greatest achievement was cracking the Enigma, a mechanical device used by the German army to encode secure messages. It proved nearly impossible to decrypt without the correct cipher, which the German forces changed every day. Turing worked to decipher German naval communications at a point when German U-boats were sinking ships carrying vital supplies across the Atlantic between Allied nations. In 1941, Turing and his team managed to decode the German Enigma messages, helping to steer Allied ships away from the German submarine attacks. In 1942, he traveled to the U.S. to help the Americans with their own codebreaking work.

3. HE BROKE THE RULES TO WRITE TO CHURCHILL.

Early on, Bletchley Park’s operations were hampered by a lack of resources, but pleas for better staffing were ignored by government officials. So, Alan Turing and several other codebreakers at Bletchley Park went over their heads to write directly to Prime Minister Winston Churchill. One of the codebreakers from Bletchley Park delivered the letter by hand in October 1941.

“Our reason for writing to you direct is that for months we have done everything that we possibly can through the normal channels, and that we despair of any early improvement without your intervention,” they wrote to Churchill [PDF]. “No doubt in the long run these particular requirements will be met, but meanwhile still more precious months will have been wasted, and as our needs are continually expanding we see little hope of ever being adequately staffed.”

In response, Churchill immediately fired off a missive to his chief of staff: “Make sure they have all they want on extreme priority and report to me that this had been done.”

4. HE HAD SOME ODD HABITS.

Like many geniuses, Turing was not without his eccentricities. He wore a gas mask while riding his bike to combat his allergies. Instead of fixing his bike’s faulty chain, he learned exactly when to dismount to secure it in place before it slipped off. He was known around Bletchley Park for chaining his tea mug to a radiator to prevent it from being taken by other staffers.

5. HE RODE HIS BIKE 60 MILES TO GET TO THE FIRST DAY OF SCHOOL.

Though he was considered an average student, Turing was dedicated enough to his schooling that when a general strike prevented him from taking the train to his first day at his new elite boarding school, the 14-year-old rode his bike the 62 miles instead.

6. HE TRIED OUT FOR THE OLYMPICS.

Turing started running as a schoolboy and continued throughout his life, regularly running the 31 miles between Cambridge and Ely while he was a fellow at King’s College. During World War II, he occasionally ran the 40 miles between London and Bletchley Park for meetings.

He almost became an Olympic athlete, too. He came in fifth place at a qualifying marathon for the 1948 Olympics with a 2-hour, 46-minute finish (11 minutes slower than the 1948 Olympic marathon winner). However, a leg injury held back his athletic ambitions that year.

Afterward, he continued running for the Walton Athletic Club, though, and served as its vice president. ”I have such a stressful job that the only way I can get it out of my mind is by running hard,” he once told the club’s secretary. “It's the only way I can get some release."

7. HE WAS PROSECUTED FOR BEING GAY.

In 1952, Turing was arrested after reporting a burglary in his home. In the course of the investigation, the police discovered Turing’s relationship with another man, Arnold Murray. Homosexual relationships were illegal in the UK at the time, and he was charged with “gross indecency.” He pled guilty on the advice of his lawyer, and opted to undergo chemical castration instead of serving time in jail.

8. THE GOVERNMENT ONLY RECENTLY APOLOGIZED FOR HIS CONVICTION …

In 2009, UK Prime Minister Gordon Brown issued a public apology to Turing on behalf of the British government. “Alan and the many thousands of other gay men who were convicted as he was convicted under homophobic laws were treated terribly,” Brown said. "This recognition of Alan's status as one of Britain's most famous victims of homophobia is another step towards equality and long overdue." Acknowledging Britain’s debt to Turing for his vital contributions to the war effort, he announced, “on behalf of the British government, and all those who live freely thanks to Alan's work I am very proud to say: we're sorry, you deserved so much better."

His conviction was not actually pardoned, though, until 2013, when he received a rare royal pardon from the Queen of England.

9. … AND NAMED A LAW AFTER HIM.

Turing was only one of the many men who suffered after being prosecuted for their homosexuality under 19th-century British indecency laws. Homosexuality was decriminalized in the UK in 1967, but the previous convictions were never overturned. Turing’s Law, which went into effect in 2017, posthumously pardoned men who had been convicted for having consensual gay sex before the repeal. According to one of the activists who campaigned for the mass pardons, around 15,000 of the 65,000 gay men convicted under the outdated law are still alive.

10. HE POISONED HIMSELF … MAYBE.

There is still a bit of mystery surrounding Turing’s death at the age of 41. Turing died of cyanide poisoning, in what is widely believed to have been a suicide. Turing’s life had been turned upside down by his arrest. He lost his job and his security clearance. By order of the court, he had to take hormones intended to “cure” his homosexuality, which caused him to grow breasts and made him impotent. But not everyone is convinced that he died by suicide.

In 2012, Jack Copeland, a Turing scholar, argued that the evidence used to declare Turing’s death a suicide in 1954 would not be sufficient to close the case today. The half-eaten apple by his bedside, thought to be the source of his poisoning, was never tested for cyanide. There was still a to-do list on his desk, and his friends told the coroner at the time that he had seemed in good spirits. Turing’s mother, in fact, maintained that he probably accidentally poisoned himself while experimenting with the chemical in his home laboratory. (He was known to taste chemicals while identifying them, and could be careless with safety precautions.)

That line of inquiry is far more tame than some others, including one author’s theory that he was murdered by the FBI to cover up information that would have been damaging to the U.S.

11. HIS FULL GENIUS WASN’T KNOWN IN HIS LIFETIME.

Alan Turing was a well-respected mathematician in his time, but his contemporaries didn’t know the full extent of his contributions to the world. Turing’s work breaking the Enigma machine remained classified long after his death, meaning that his contributions to the war effort and to mathematics were only partially known to the public during his lifetime. It wasn’t until the 1970s that his instrumental role in the Allies' World War II victory became public with the declassification of the Enigma story. The actual techniques Turing used to decrypt the messages weren’t declassified until 2013, when two of his papers from Bletchley Park were released to the British National Archives.

12. THE TURING TEST IS STILL USED TO MEASURE ARTIFICIAL INTELLIGENCE …

Can a machine fool a human into thinking they are chatting with another person? That’s the crux of the Turing test, an idea developed by Turing in 1950 regarding how to measure artificial intelligence. Turing argued in his paper “Computing Machinery and Intelligence” [PDF] that the idea of machines “thinking” is not a useful way to evaluate artificial intelligence. Instead, Turing suggests “the imitation game,” a way to assess how successfully a machine can imitate human behavior. The best measure of artificial intelligence, then, is whether or not a computer can convince a person that it is human.

13. … BUT SOME CONSIDER IT TO BE AN OUTDATED IDEA.

As technology has progressed, some feel the Turing test is no longer a useful way to measure artificial intelligence. It’s cool to think about computers being able to talk just like a person, but new technology is opening up avenues for computers to express intelligence in other, more useful ways. A robot’s intelligence isn’t necessarily defined by whether it can fake being human—self-driving cars or programs that can mimic sounds based on images might not pass the Turing test, but they certainly have intelligence.

14. HE CREATED THE FIRST COMPUTER CHESS PROGRAM.

Inspired by the chess champions he worked with at Bletchley Park, Alan Turing created an algorithm for an early version of computer chess—although at that time, there was no computer to try it out on. Created with paper and pencil, the Turochamp program was designed to think two moves ahead, picking out the best moves possible. In 2012, Russian chess grandmaster Garry Kasparov played against Turing’s algorithm, beating it in 16 moves. “I would compare it to an early caryou might laugh at them but it is still an incredible achievement," Kasparov said in a statement after the match-up.

15. THERE IS ALAN TURING MONOPOLY.

In 2012, Monopoly came out with an Alan Turing edition to celebrate the centennial of his birth. Turing had enjoyed playing Monopoly during his life, and the Turing-themed Monopoly edition was designed based on a hand-drawn board created in 1950 by his friend William Newman. Instead of hotels and houses, it featured huts and blocks inspired by Bletchley Park, and included never-before-published photos of Turing. (It’s hard to find, but there are still a few copies of the game on Amazon.)

The 19th Century Poet Who Predicted a 1970s Utopia

In 1870, John Collins dreamed of a future without cigarettes, crime, or currency inflation. The Quaker poet, teacher, and lithographer authored "1970: A Vision for the Coming Age," a 28-page-long poem that imagines what the world would be like a century later—or, as Collins poetically puts it, in "nineteen hundred and threescore and ten.”

The poem, recently spotlighted by The Public Domain Review, is a fanciful epic that follows a narrator as he travels in an airship from Collins’s native New Jersey to Europe, witnessing the wonders of a futuristic society.

In Collins’s imagination, the world of the future seamlessly adheres to his own Quaker leanings. He writes: “Suffice it to say, every thing that I saw / Was strictly conformed to one excellent law / That forbade all mankind to make or to use / Any goods that a Christian would ever refuse.” For him, that means no booze or bars, no advertising, no “vile trashy novels,” not even “ribbons hung flying around.” Needless to say, he wouldn’t have been prepared for Woodstock. In his version of 1970, everyone holds themselves to a high moral standard, no rules required. Children happily greet strangers on their way to school (“twas the custom of all, not enforced by a rule”) before hurrying on to ensure that they don’t waste any of their “precious, short study hours.”

It’s a society whose members are never sick or in pain, where doors don’t need locks and prisons don’t exist, where no one feels tempted to cheat, lie, or steal, and no one goes bankrupt. There is no homelessness. The only money is in the form of gold and silver, and inflation isn't an issue. Storms, fires, and floods are no longer, and air pollution has been eradicated.

While Collins’s sunny outlook might have been a little off-base, he did hint at some innovations that we’d recognize today. He describes international shipping, and comes decently close to predicting drone delivery—in his imagination, a woman in Boston asks a Cuban friend to send her some fruit that “in half an hour came, propelled through the air.” He kind of predicts CouchSurfing (or an extremely altruistic version of Airbnb), imagining that in the future, hotels wouldn't exist and kind strangers would just put you up in their homes for free. He dreams up undersea cables that could broadcast a kind of live video feed of musicians from around the world, playing in their homes, to a New York audience—basically a YouTube concert. He describes electric submarines (“iron vessels with fins—a submarine line, / propels by galvanic action alone / and made to explore ocean’s chambers unknown") and trains that run silently. He even describes climate change, albeit a much more appealing view of it than we’re experiencing now. In his world, “one perpetual spring had encircled the earth.”

Collins might be a little disappointed if he could have actually witnessed the world of 1970, which was far from the Christian utopia he hoped for. But he would have at least, presumably, really enjoyed plane rides.
