50 Incredible “Did You Know” Facts That Will Astonish Everyone

One of the best things about learning something new is being able to share that knowledge with others. And while some facts are weird and wonderful and others are totally useless, there’s a whole category of trivia that is just so incredible you can’t resist asking everyone you meet “Did you know this?!”

From why grapes go on fire in the microwave to how long it takes the average mammal to urinate, these are the did you know facts that will fascinate you and your friends. 

1
Did you know grapes light on fire in the microwave?

healthy eating scenes, did you know facts

Back in 2011, a physicist at the University of Sydney went viral after he placed a grape in the microwave and filmed the fiery aftermath. And oddly enough, scientists couldn’t explain the phenomenon until quite recently. A March 2019 study published in Proceedings of the National Academy of Sciences reported that the fruity fireball occurs as a result of the loose electrons and ions that cluster to form plasma when grapes get hot.

Did you know there are almost 8 million possible seven-digit phone numbers per area code?

Each area code has 792 possible prefixes or NXX codes (for example, NXX-XXXX or 555-1234), explains the Public Utility Commission of Texas. And each “NXX” has 10,000 possible phone numbers attached to it. So, with a little math, we know that theoretically, there are 7,920,000 possible seven-digit phone numbers in each area code. Obviously, not all of these numbers are put into use, so you don’t have to try nearly 8 million numbers if you’re trying to randomly dial a friend who lives nearby.

3
Did you know spaghetto, confetto, and graffito are the singular forms of spaghetti, confetti, and graffiti?

plate of spaghetti on table, did you know facts

Although it might sound a little strange, the word for an individual piece of spaghetti is spaghetto. The same goes for a single piece of confetti, which is confetto, as well as a single piece of graffiti, which is graffito, according to Merriam-Webster

4
Did you know McDonald’s once created bubblegum-flavored broccoli?

Best Foods for Maximizing Your Energy Levels

McDonald’s is always introducing new items for their loyal customers. And obviously, some are more successful than others. But their bubblegum-flavored broccoli, which the fast-food chain developed in 2014 as a tastier version of the leafy green for children, was a complete failure. McDonald’s CEO Don Thompson admitted that kids were confused by the taste.

5
Did you know the average mammal takes 21 seconds to empty its bladder?

Bad bosses, bathroom break, weird laws, did you know facts

No one will blame you if you’ve never bothered to time yourself on the toilet. But you may be interested to know that researchers from the Georgia Institute of Technology found that most mammals weighing more than six pounds take 21 seconds to pee. According to Live Science, this oddly consistent time is due to the fact that the urethra is “appropriately scaled” to be a “flow-enhancing device.” And apparently, the perfectly enhanced flow takes 21 seconds to complete. It’s one of the perfect did you know facts to try at home!

6
Did you know chewing gum is banned in Singapore?

weird laws

Along with having laws against spitting and urinating anywhere but in a toilet (which you’re then legally obligated to flush if it’s a public washroom), Singapore has also banned chewing gum in an effort to keep the city clean and orderly. The ban was established in 1992. In 2004, exceptions were made for therapeutic, dental, or nicotine gums. 

7
Did you know the average U.S. household has 300,000 things in it?

Whether you’ve been inspired by Marie Kondo or not, you probably still have close to a third of a million items in your home. One report found that the average U.S. house has around 300,000 things in it. Yeah, we like stuff. Lots of stuff.

8
Did you know the 1939 novel Gadsby is the longest book ever published that doesn’t contain the letter ‘e’?

This is the front cover art for the book Gadsby: A Story of Over 50,000 Words Without Using the Letter "E" written by Ernest Vincent Wright. Wikimedia Commons/Wetzel Publishing

Back in 1939, American author Ernest Vincent Wright published Gadsby, a 50,000-word novel that doesn’t use the letter ‘e’ once. What’s more, it’s not the only novel that ditched the letter. Author Georges Perec also wrote the French-language book La Disparition without the letter ‘e’ in 1969. That’s even more astounding when you consider that the letter ‘e’ is the most commonly used letter in the English (and French!) language. 

9
Did you know lobsters have clear blood?

lobster on table, did you know facts

Most of us are well aware that lobster shells change color when exposed to heat (like in a pot of boiling water, for example). But the sea creatures’ blood is also intriguing. Lobster blood is initially clear and turns blue when it hits oxygen.

10
Did you know the first item sold on eBay was a broken laser pointer?

eBay

Buyer beware, as they say. Thankfully, buyer Mark Fraser was apparently aware of the fact that he was getting a broken laser pointer when he purchased it for $14.83 from eBay’s founder Pierre Omidyar in 1995. 

11

The Japanese city of Iga, which has a rich history of martial arts masters and claims to be the birthplace of the ninja, is suffering from a ninja shortage, despite the fact that they’re willing to pay salaries as high as $85,000 for the performative ninjas willing to take on the job of staffing their annual ninja festival.

Unfortunately, this is one of the did you know facts you probably can’t repeat to your friends—and that’s because it’s nearly impossible to pronounce. Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenuakitanatahu is in New Zealand and is 85 letters long. And when it comes to other super long place names, it’s followed by Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch in Wales, Chargoggagoggmanchauggagoggchaubunagungamaugg in the U.S.,  Tweebuffelsmeteenskootmorsdoodgeskietfontein in South Africa, and Azpilicuetagaraycosaroyarenberecolarre in Spain.

13

More than 300 million years ago, the Meganeura established itself as the largest known flying insect to ever exist on Earth. The dragonfly-like creature had a wingspan that stretched around 2.5 feet. The bugs were also big enough to hunt prey like frogs and newts which it could eat with its teeth-like mandibles. 

14
Did you know bubble wrap was originally invented as wallpaper?

bubble packing material, did you know facts

If you can’t wait to pop every air-filled pocket the minute you pull a piece of bubble wrap out of a package, can you imagine how irresistible it would be if it was covering your walls? Engineer Al Fielding and Swiss inventor Marc Chavannes probably didn’t consider that when, in 1957, they invented bubble wrap while trying to create a textured wallpaper by sealing two shower curtains together to trap air bubbles.

15
Did you know Shakespeare invented more than 1,700 words?

Shakespeare wax figure, did you know facts

Shakespeare wrote some of the most beloved and revered pieces of literature the world has ever known, but in order to craft his plays and poems, he sometimes resorted to making up his own words. In fact, the Bard is said to have come up with more than 1,700 words including moonbeam, laughable, eyeball, bump, puking, champion, bedroom, excitement, and zany. 

16
Did you know Santa Claus was given an official pilot’s license in 1927?

sleigh santa facts

When Santa Claus makes his trip around the world on Christmas Eve, you can rest assured that he’s legally allowed to drive his sleigh—at least in the United States. In 1927, the jolly man in the red suit was given a pilot’s license from the Assistant Secretary of Commerce for Aeronautics William P. MacCracken.

According to the Library of Congress, “The old saint called at the Commerce Department in Washington” and when he arrived, his picture was taken as he was given his license, airway maps, “and the assurance that the lights would be burning on the airways on Christmas Eve.” 

17
Did you know Einstein’s brain was stolen when he died?

Albert_Einstein

When Nobel Prize-winning physicist Albert Einstein passed away on April 18, 1955, he left behind specific instructions when it came to the disposal of his body, according to one National Geographic investigation. Einstein didn’t want his corpse to be worshiped or his brain to be studied, so he instructed those who were responsible for his remains to “cremate them, and scatter the ashes secretly in order to discourage idolaters.”

However, Thomas Harvey, the pathologist on call when Einstein died at New Jersey’s Princeton Hospital, didn’t quite follow those instructions. Instead, he stole Einstein’s brain. From there, things got even weirder. When Einstein’s family found out, his son apparently didn’t object to the theft and Harvey was able to keep the brain in two jars in his basement before moving it to “a cider box stashed under a beer cooler.”

18
Did you know a single watermelon once sold for $6,125?

In 2008, a man in Japan bought a nearly black Densuke watermelon for ¥650,000 or $6,125. The specialty fruit is only grown on the island of Hokkaido and, according to a Japanese agricultural expert in the Los Angeles Times, is crisp and hard with “a different level of sweetness” than the watermelon we’re used to eating.

Female Cow Animal Jokes

Joao Maria de Souza was lying in bed in 2013 when a cow that had been grazing on a hill behind his house walked onto the asbestos roof and fell through, landing on de Souza, according to the BBC. The injured man was taken to hospital where he later passed away. As strange as this incident might seem, locals claim that it was the third time a similar thing had happened in the area in the past three years, although no one was killed the first two times.

20
Did you know scientists made a “nanoguitar” the size of a human blood cell?

Cornell University researchers carved the tiny musical instrument out of crystalline silicon and claim that it’s the world’s smallest “nanoguitar” at 10 micrometers long. The guitar’s six strings are each about 50 nanometers (100 atoms) wide. And while it was “made for fun to illustrate the technology,” it also demonstrates how this tech could be used in fiber optics, displays, sensors, and electronics.

23
Did you know “arachibutyrophobia” is the fear of peanut butter sticking to the roof of your mouth?

bad jokes that are actually funny

It’s pretty common to be afraid of heights and scared of spiders, but if you have arachibutyrophobia, you’re among the smaller group of people that suffer from a fear of peanut butter sticking to the roof of their mouths. This phobia is often connected to a fear of choking or a fear of sticky textures, but it can also be its own isolated fear.

24

The crowd’s reaction to the game’s final pass registered as an earthquake by a seismograph located around 1,000 feet from the stadium. A seismologist noticed the reading the next day and the game went down in LSU history as the “Earthquake Game.”

Garry Turner from the U.K. holds the Guinness World Record for stretchiest skin thanks to the fact that he can extend the skin on his stomach 15.8 centimeters.

Mouse brain {best of 2018}

Fictional Marvel characters aren’t the only beings with superhero-like powers. A few lucky mice were given the ability to see in perfectly in the dark when scientists utilized nanoparticles that convert infrared light to visible light. The same method could be used to give humans the same night-vision superpower sometime in the future. We’ll just have to wait and see.

There are plenty of extreme sports out there if you happen to be an adrenaline junkie. From the classics like skydiving and surfing to newcomers like parkour and blobbing (A.K.A. human catapulting), there’s truly something for everyone. But if you want to combine your love of cleaning with your love of getting wild, then perhaps you’d like to try extreme ironing, which was founded in 1997 and has been challenging competitors to press shirts in unexpected locations—like high up in trees, hanging over cliffs, or paddling white-water rapids—for more than two decades.

Cruise ship lifeboat

Other than the fact that it hit an iceberg and sank, a lot went wrong during the Titanic tragedy.

Edward Norton in Fight Club (1999), smarter facts IMDB/Fox 2000 Pictures

It’s not quite true that there’s a Starbucks on every single corner in every major city. But there does happen to be a Starbucks cup in every scene in the 1999 movie Fight Club starring Brad Pitt, Edward Norton, and Helena Bonham Carter. The cup’s appearance was reportedly inspired by a line in the film, when Norton’s character explains, “When deep space exploration ramps up, it’ll be the corporations that name everything, the IBM Stellar Sphere, the Microsoft Galaxy, Planet Starbucks.” You can view all of the cups on this comprehensive Tumblr page

In October 2018, Gilbert Minnesota Police Department issued a public notice about birds that appeared to be “under the influence.” It turns out that the airborne animals were apparently eating berries that had fermented due to early frost which was making them “tipsy.” Unfortunately, this meant that the buzzed birds were acting confused and flying into windows. Hopefully, they were able to sleep it off.

haumea planet in space with moons, did you know facts

This dwarf planet is cool for a number of reasons. About the same size as Pluto, Haumea orbits the sun beyond Neptune and has rings similar to Jupiter. But what makes this object even more interesting is that it’s shaped like a potato.

There’s no doubt that Darth Vader’s getup is pretty snazzy in Star Wars, but according to Time, it’s probably out of your budget.

45
Did you know that shark attacks threaten the internet?

If shark attacks give you the chills, you’re not alone. And the people over at Google can sympathize thanks to the fact that they deal with shark attacks that threaten the internet. And this isn’t a new problem. Back in 1987, the New York Times reported that is was an issue with phone lines at the time due to the fact that “sharks have shown an inexplicable taste for the new fiber-optic cables that are being strung along the ocean floor linking the United States, Europe, and Japan.”
