Someone Asked, ‘What’s A Cool Fun Fact That You Know?’, 40 People Delivered
As of January 2021, there were 4.66 billion active internet users worldwide, which makes 59.5% of the global population. Of this total, 92.6% (4.32 billion) accessed the internet via mobile devices, Statista estimates. So just imagine how much information there is online. In fact, it’s probably impossible to wrap your head around it.
Part of the appeal in going online is that you get to share things with others. From what you’ve been up to, to what’s on your mind. Quite literally. Like this recent thread on Reddit, where the user Mistik06 asked everyone “What’s a cool fun fact that you know?” and got people posting the craziest facts they know. 24k upvotes and 10.7k comments later, we have an amazing collection of trivia facts you probably haven't heard of before, so enjoy!

Pufferfish contain a toxin in their spikes that kills predators. It has a slightly different effect on dolphins though, in that it gets them high. So teenage dolphins will pass around pufferfish and impale themselves off of them to get stoned.
Someone better let the pufferfish know. They could build a successful drug empire off it. Puff Cartel.
Apparently, studies show that Crows, Ravens and other Corvids are self aware and are able to ponder the content of their own minds.
Dragonflies are the predator with the highest success rate (over 90%), and are one of the few animals that are capable of plotting intercept courses rather than chasing their prey. They're basically mosquito murder drones.
Elephants think humans are cute in the same way we think puppies and kittens are cute.
Scientists speculated there are other planets orbiting distant stars, but haven't had a clear evidence of this fact up until the 1990's. And the majority of currently known exoplanets (almost 5000, as of now!) have been discovered well into 2000's, which means that humanity is at the very beginning of its discovery journey regarding other planetary systems.
With James Webb telescope being extremely close to finalizing its calibrations as we speak, we will be able to not only discover hundreds, if not thousands of new planets (and stars and galaxies), but also detect whether there are traces of alien civilizations on them. We should all be very excited about this, as this is unprecedented, and a HUGE deal for science and our species as a whole.
This is amazing. Sometimes I wonder what it would be like to be born 100 years from now, how advanced would we be.
Ok, this fact has connected facts:
In late 1800s girl killed herself by jumping from bridge on Sienna river and she was known as The Unknown Woman of the Seine.
When the guy who worked in morgue saw her, he thought she was beautiful and ordered a plaster cast of her face.
Fast foward to 1960s, CPR was invented and they needed a doll to train people. So they partnered with Norwegian producer of medical devices. That guy decided to use the plaster cast of Unknown Woman of the Seine and named the doll Anne(Annie) because his doughter was named Anne(Annie).
While performing CPR, people were trained to talk to a doll(person) so there is that common phrase:"Annie! Annie are you ok?"
Fast foward to when Michael Jackson decided to put that phrase in his classic "Smooth Criminal".
When Thomas Edison was bound to a wheelchair, Henry Ford bought a wheelchair for himself so that he and Edison could race.
Steven Seagal once told Gene LeBell that he was immune to being choked out from doing so much martial arts training, so Gene choked him out and he sh*t his pants.
When sea otters find a rock they like to bust open clams, they will tuck it under a fold of skin in their armpit. They also hold each other’s paws while they’re sleeping so they don’t float away from each other. Baby otters aren’t buoyant enough to stay afloat so they will sleep on their mom’s tummies until they’re older.
The creator of the pop-up ad made a formal apology for his creation.
Dinosaurs existed for so long that there were still dinosaur fossils from previous eras while other dinosaurs from future eras were alive.
So basically, when T-Rex was still alive and well, Stegosaurs was nothing more than fossilized bones under their feet even back then.
You can fit the entire population of the human race inside the Grand Canyon. Not just the 7 billion alive now - the entire lot. From the very start. And still have plenty of room for those who are yet to be born.
If every person on earth fought 1v1 until there was only 1 winner, that person would only have to win 33 times.
The sound of an ATM drawing cash is a manufactured sound. It's just to let you know that the ATM is indeed working and that your money is coming up.
That if sound could be transmitted through space, the sun would be so loud on earth it would be the equivalent of standing next to a jet engine, even though it's 94 million miles away.
Sound in space travels along gravitational waves and can also be picked up via vibrations. Space agencies have been listening to the sun and planets for years (Jupiter and Saturn sound particularly scary).
Your nose is impacting your vision 100% of the time.
However, since your "picture" you see is just an interpretation by your brain, your brain erases your nose as useless information. You'll only see it, if you really concentrate on it, if you close one eye, or if you put your finger on the very tip of your nose.
It seems like a harmless fact until this thought enters your head...
"Your nose is real. Your brain removes it from your vision as useless, but it is very much there, and very much real. What other things is your brain removing from your vision?"
It's wild to think that your entire life experience is just your brain doing it's best to interpret your senses. And that it's definitely not a "perfect" system. It could be interpreting everything incorrectly, and we collectively wouldn't have any idea.
Moose are really good swimmer's and even swim from island to island to feed on the underwater vegetation
But orcas will occasionally stumble across then and hunt them down and moose haven't evolved far enough for them to know that orcas are predators
Cracking your knuckles WILL NOT lead to arthritis.
Brace yourself, You also don’t need to wait two hours after a meal to go for a swim.

Once worked with a guy who did this constantly. The urge to beat him to death with a 2x4 was overwhelming.
I've found a kindred spirit! The sound drives me mad too.

Did everyone else immediately crack their knuckles after reading this?
I got the feeling but sadly I already did just before reading it and now I feel empty :(

It mere burst the air bubble, which then reforms. Sounds horrible though.
I think it's a build up of nitrogen in the knuckle joints which as you say 'pops' I've done it for 30+ years without any issues yet! (I feel ive just jinxed this now 😂)

It sounds disgusting. I wish people would stop doing it in public. :-|
Your face will NOT get stuck like that and something else won't make you go blind either...
The "crack" is simply a cavitation created when two joint surfaces which are usually under compression are fractionally separated. The resulting vacuum draws nitrogen, which has disolved into the articular cartilage, out at the same time synovial fluid (our natural joint lubricant) is rushing into the same space and which collapses the nitrogen bubble. The joit feels freer as there is not lubricant between the two joint surfaces. It takes ~45-60 minutes for the nitrogen to disolve back into the cartilage. A similar effect is created when divers ascend from depth too quickly but the nitrogen bubbles form more aggressively in the joints (joint pain which improves with pressure) and in the blood stream which is usually the part that causes the long term and vastly mpore harmful effects of "the bends"
60+ years cracking my knuckles. No deformations or limited range. Full mobility/flexibility. People are shocked when they hear this.
Mt younger son did this all the time as a young boy. Of course I told him it was a bad thing, and once at the doctor's office mentioned it hoping for support. Very young and new doctor contradicted me. Right after, saw him telling an older doctor and looking sheepish. Yeah, proving his Mom was a liar to a kid. I should have given him "the look." I don't care if it isn't bad for you. It's bloody annoying when it is done on purpose to annoy. My son is in his 50s now. He still remembers and thinks it's funny. 😎
It may not lead to arthritis, but it can lead to mild, temporary pain in the hand.
So, interestingly enough, this is still debated between physicians... Standard imaging techniques have been too slow for the crepitation to be caught by imaging. The theory is that it is air bubbles popping, but new imaging techniques have suggested the sound we hear might actually be the sound of air bubbles reforming really quickly after being popped, super interesting imo! Gotta love how medicine/science is always evolving!

The difference between Million and Billion is more than we think.
To put it in perspective, 1 million seconds is about 12 days while 1 billion seconds is equivalent to 31.7 years.
Birds are classified as extant dinosaurs, not just descended from them. They are actual living, breathing dinosaurs.
Manatees regulate buoyancy by farting. They eat a ton of plants and accumulate a lot of methane. They then release gas when they want to sink and hold it in when they want to go to the surface or are being polite.
A single gram of DNA contains about 700 terabytes of information.
When they first measured the height of Mt. Everest it was exactly 29.000 feet, but as that sounds like a made-up number they declared it to be 29.002 feet.
Sharks like and get attracted to Heavy Metal music played underwater.
If you made $10,000 per day, every day since the pyramids were built around 4,500 years ago, you'd have 6% of Elon Musk's wealth.
You don't use shock paddles on a stopped heart.
Shock paddles simply put a heart back in to a natural rhythm, they will not restart a heart if it has stopped. That's what chest compressions are for.
And you actually have a very high mortality rate if you need chest compressions or a heart shock. The 5 year survival rate for both is very low.
Grass evolved 66 million years ago.
Dinosaurs went extinct 65 million years ago.
The vast majority of dinosaurs never existed at the same time as grass.
Cuttlefish can accurately match the color and texture of their environment despite the fact that they’re colorblind.
Koalas are literally smooth-brained, so much so that if you put a plate of eucalyptus leaves in front of them that have been taken off the branch, they won’t recognize them as food.
The Nazis planned to assassinate Winston Churchill with an explosive chocolate bar.
16⁰C and 28⁰C reversed are equal to their Fahrenheit value. So - 16 is 61f and 28 is 82f
Marlon Brando popularised wearing a T-shirt casually.
There are more plastic flamingo lawn ornaments in the US than there are wild flamingoes on the entire planet.
There is a plant called the California Corn Lilly that contains a drug called Cyclopamine. When animals eat it while pregnant, it can cause cyclopia (one eye). It inhibits a signaling pathway called the Sonic Hedgehog Pathway (yes, this pathway was actually named after the video game).
The sonic gene is a gene which determines how many digits/fingers a being has
The only artist to ever have five albums in the US Top 20 at the same time is Herb Alpert & The Tijuana Brass.
If you fold a regular piece of paper in half 104 (from memory) times, the paper will be as thick as the entire observable universe.
And if you fold a piece of paper more than 300 times you end up with a book that has more pages than atoms in the observable universe

There are so many apple varieties around the world, that if you were to eat a different apple variety every day, it would take you over 20 years to get through them.
Hooray for so many apples that are not red delicious!
