What's the wildest random fact you know, Pandas? Have you ever heard that flour is insanely flammable, especially when dispersed and thrown into the air? Or did you know that Subway bread contains so much sugar in it that, in Ireland, they're not allowed to legally call it "bread?"
We just found out about these and more interesting gems from several threads online. In one of them, one netizen asked, "What is [the] most 'Why the [heck] do you know that?' fact?" In another, a Threads user wrote: "Teach me something new today. Drop a fact [that is] useless, funny, random… let's share what we know."
And people didn't disappoint, as their brains seem like sponges for useless but fascinating facts. We've gathered the most interesting tidbits of knowledge from these online threads and present the wildest to you here. For example, read on to find out what distance it takes for a human to hear a blue whale's heartbeat!

Opossums are not related to rodents they are North American marsupials and are related to kangaroos. Also! Their natural body temperature is so low that the rabies virus can barely survive in their system. They can’t get lyme disease. And! They eat approximately two thousand ticks a week. They are immune to most snake venom. They’re the best. 🖤

An internet modem is named that because in the early days of the "internet" you'd use a modulator and a demodulator to send and receive signals. When engineers figured out how to put it in one unit, they shortened the name to MoDem, short for modulator/demodulator.

There are 4 suits in a deck of cards, 1 for each season
There are 52 cards, for the 52 weeks in a year
If you number each card with ace as 1 up to 13 then add all the cards together you get 364.
Add one joker and it’s 365, for the days of the year.
Add the other joker and it’s 366, for a leap year.

My mid school teacher was explaining about Spanish exploration of the New World, and he asked us if we know about the Aztec. I promptly raised hand and tell the class about their brief history until their demise under the Spanish, in which my teacher was impressed. Little did he know that all i did was just recites the entirety of Moctezuma campaign from Age of Empires 2.

Back in high school my human geography teacher had a map of European ethnicities on the board and questioned out loud why the Hungarian people were called "Magyars", to which I promptly raised my hand and told him it was because in Hungarian the country is called Magyarorszag (don't remember how it's spelled). Needless to say the room was very impressed.
But I didn't have the heart to tell him it was because I was a Hetalia fan.
EDIT: I guess some people didn't take "Human Geography" in school, but it's the name of the subject. Nonetheless my instructor was indeed of the homo sapien species... or so I was made to believe.

If you mix 95% water and 5% potassium hydroxide, in a metal tube with a body inside and heat it up for four to six hours, all that will be left are squishy bones. You can run that through a cremulator and pour sulphuric acid on it to get rid of the bones. It's alkaline hydrolysis. The sulphuric acid thing I added for spice- but yeah. It's actually alot more eco-friendly friendly option than cremation so xD.

Mantis shrimp have a punch so fast that it boils the water around the punch. With a speed roughly that of a .22 caliber bullet, it can stun some fish instantly and even break a man's finger.

"boils" gives the wrong image, but that's basically correct. Mantis shrimp are known to reef divers as "thumb splitters". Look up "cavitation". Any blunt object travelling faster than the speed of sound in water generates a vapour bubble.

The act of throwing somebody out of a window is called defenestration.
The act of of throwing somebody into a fire is called decrepitation.
Floccinaucinihilipilification is the act of judging something as worthless.
So technically you could do all three in just a few seconds. You could floccinaucinihilipilificate a person and choose to both defenestrate and decrepitate them in response if there is a fire lit underneath the window you plan to throw them from. Don't do that tho, I just like silly words.

Horses are obligate nose breathers. Plug their nose and they'll suffocate. Horses can't burp or vomit - the system is one way only. Horses can "passively breathe" while running at high speeds. Their guts slosh around back to front rhythmic pushing air out and pulling it in.

Your brain consumes about 20% of your energy, even when you’re doing nothing… Thinking is one of the most expensive things you do. So make sure whatever you’re thinking about is literally worth the effort.
Robin Roper 9 hours ago
I have two cochlear implants. "Hearing" with these takes far more energy than natural hearing. First my brain has to process the sounds then has to process the meaning of what I am hearing - it's twice the amount of work. The device that attaches to the skull is called a "processor." This device turns sound waves into digital signals which are then sent to the internal receiver which converts these digital signals into electrical impulses which are then sent to electrodes surgically placed in the cochlea. If I'm in a setting where I have to process a lot of conversation, such a meeting or family/friend social event, I become exhausted and have to sleep to recover. I once slept 19 straight hours after a particularly long (4 hours) extensive "mapping & tuning" (adjustment) of my processors.

A Portuguese Man of War isn't technically a jellyfish, but is actually a siphonophore, where several organism comprise themselves to create a larger collective of one.

Recycling of plastics is useless.
The time, money and energy used to do so are are no more green than producing raw plastic from crude sources, and are mainly done because many people don't know what else to do (we gotta do something, right?). And the plastics that are successfully recycled tend to be lower grade than raw, their hydrocarbon chains are weakened, Of course there are compromises, trade-offs and uses for these recycled plastics, but they aren't applicable large scale. The best solution is to reduce the amount of plastics used in the first place.
The cost/benefit of recycling paper, glass and metal is worth it, but not so for plastic.

Koalas have smooth brains. This is bc they are so low effort and only eat eucalyptus (which is actually toxic to them). When they are babies they can’t start eating the leaves as soon as they can eat solids they actually attach themselves to their moms rectum and eat their moms poop to start gaining the immunity to the eucalyptus poison.

Rabbits eat their own p**p their entire lives. They eat grass and other vegetation, but don't have the chambered stomach like a cow does, so they can't digest it well. So the first time it exits the system, they eat it again, and their digestive system gets more nutrition from it. This is why it's hard to rescue a baby rabbit. They need to eat their parents p**p to get enzymes to digest properly. As soon as you try to wean a baby rabbit, without the help of an adult rabbit, the baby rabbit will unalive.

The buried treasure of Montezuma is most likely near Kanab, Utah. Misfortune has met nearly anyone who has tried to get into the underwater cave it is suspected to be in.
People have tried to drill through the ground above the cave and they found gold on the drill bit, but the driller and his wife passed away from heart conditions and such that night. The hole was sealed with cement afterwards. Divers who searched for the treasure reported seeing ghosts of Native Americans and such guarding the area while others had their oxygen tanks shut off and their regulators ripped out.
Montezuma was known to have his men sacrificed when they buried treasure so that their spirits would guard it. I have personal connections to one of the first divers who went down there, but he, like most of the other divers, refuses to talk about what happened down there. He just warns people to leave it alone, and he hasn't been the same since he went down there.
I've been to that exact lake a few times in my life. It is the most eerily still place I've been to in that state and it has a highway right next to it for crying out loud. Something or someone wants the blood money of Montezuma to stay far away from modern human hands as possible.

Humans can become more flexible based on the visual field.
Most of this stuff how freely you are to move your muscles is center brain region controlled which gets info from our visual field.
If you do a wide stretch. And then you turn your gaze there, and try to go further out. Your brain will allow you more muscle movement.. next time you do the stretch you will be more flexible. In fact 25-40% more in some cases.
In fact visual system is hella interesting it's nuts how much it directs from time perception to how focussed and awake we are because we also have cells in our eyes that are angled Slightly upwards that just scan for light intensity. They literally dictate if we are awake and alert or not... It's why skylights work and why desk ergonomics tell you to offset your screen. Because you get sleepy if you look down on the screen more or less because you drown out those cells.
Heck did you know our peripheral vision literally runs on a higher frame rate of sorts. You can literally focus on more things and spot more stuff if you train yourself to focus on your peripheral vision.. the center focus in your eyes runs slower and is processing stuff with more detail..you can train yourself to be good at wheres waldo... In fact it's why it even works. Because if you spot something that looks like waldo there's small attention dips due to dopamine release where you will literally miss waldo if he's next to the thing almost looking like him.. because our focus literally tunnel visions Like that if we don't pay attention to the periphery.

It’s pretty common for types of jellyfish to be used as cheap food fillers all over the world. chances are,if you’ve eaten a cheap eggroll or something from a random place,you probably ate jellyfish filler without knowing since they take on and absorb the taste of whatever they were added to so easily.
Liliana Spiro 4 hours ago
"While jellyfish is a popular, nutritious, and crunchy delicacy in many Asian cuisines (often as a salad or appetizer), it is not widely used as a "cheap food filler" in common, random, or Western-style food like egg rolls. It is highly unlikely to be hidden filler in mass-produced food due to the specific, intensive, and long-term salting process required to make it palatable." As per a quick search (several sources, one being Hakai Magazine)

Louis XIV's heart was mummified, outside his corpse, that is. It was taken from the tomb by plunderers during the revolution and came into the possession of Lord Harcourt, archbishop of York, in the first half of the 19th century. As if this isn't creepy enough, William Buckland, dean of Westminster, was given the heart in 1848 and apparently ate it!
