Why can’t you bring water on a plane? Fact Show 17

if i asked you how cashew nuts are grown what would you say prepare to have your mind blown by this revelation cashews are actually part of a tree fruit called a cashew apple the nut inside is also encased inside a shell but there's a reason why they're removed from that shell before they hit your local supermarket if you want to find out the dark secret cashews are hiding plus a whole host of more mind-blowing trivia tidbits just stick around for this episode of the ultimate fact show [Music] why can't you bring liquids on a plane picture this you hear the final boarding call and rush to make your flight when you're suddenly met with a brick wall of a man in uniform after a moment of panic he points out the bottle of water in your bag and signals to the no liquid sign we've all been there but have you ever wondered why you have to chuck your bottle at the gate the 3-1-1 rule was put in place by the transport security administration in 2006 and states that anyone boarding a plane can carry 3.4 ounces of liquid per container in a one quart bag with just one clear plastic bag per passenger according to steve hersam former deputy director of the cia's community human intelligence division this rule was the direct response to operation overt this was a term used to describe a collaborative effort to foil the plot of abdullah ahmed ali a british citizen who had known affiliations with some pretty shady guys when ali's bags were secretly searched when after returning to the uk operatives found a powdered orange soft drink and a large number of batteries in his suitcase further surveillance revealed that he and his co-conspirators had been working at a bomb-making laboratory where they drilled holes into soft drink bottles so that they could be opened with a hydrogen peroxide based liquid explosive while still appearing unopened the men planned to use the bombs on seven planes flying out of london and heading for north america but thankfully they were arrested before they could go through with it according to the tsa limiting containers to a quart-sized bag prevents what's known as a critical diameter which is basically the maximum amount needed to blow something up if you really want to get that water past security just freeze it surprisingly the tsa lets liquids on board as long as they're frozen solid or you could just chug it before boarding stop right there i may not be from the tsa but i am from the baa the be amazed administration duh and i'm here to tell you not to proceed any further until you've hit those like and subscribe buttons weekly oh and don't forget that bell icon too so you don't miss out on any more amazing content all done you're free to go who was the original peeping tom a so-called peeping tom is anyone who gets some sort of enjoyment from watching other people when they shouldn't be but who is the og tom behind the age-old phrase to find out let's travel back to the 11th century to take a look at an iconic legend surrounding a late anglo-saxon noblewoman named lady godiva as the story goes lady godiva was married to a bit of a jerk named leofrick earl of mercia who had imposed some pretty harsh taxes on the townspeople when lady godiva decided to ask her husband to lower the taxes on behalf of the people he joked that he would only do it if she agreed to ride stark naked through the streets of coventry knowing his wife's chest nature he didn't expect her to actually go through with it but lady godiva was well respected by the townspeople and they unanimously agreed to lock their windows indoors as she rode peacefully with her long locks covering up her most intimate areas this version of the story persisted right up until the 1700s when some versions began to mention a man named tom the taylor apparently this peeping tom couldn't help but catch a glimpse of lady godiva in the buff so he drilled a hole in his shutters to watch her but he paid the ultimate price some say he was literally blinded by her beauty while others say he was killed soon after whether this actually happened or whether it's a work of fiction as most historians have suggested is undecided but let this be a lesson no one likes a peeping tom apple pie isn't actually that american at some point you've probably heard the phrase as american as apple pie but get this apple pie is about as unamerican as it gets neither the apples nor the pie itself came from america yet it somehow has become a persisting symbol of americanism it's hard to say which varieties of apples first came to america because there are so many plus apple trees are easy to cross pollinate which means producing new apple varieties is pretty easy but by the 1800s american farmers were already growing an insane 14 000 types of apple the first varieties were intended for cider which means they were too tart for eating but at the same time john chapman otherwise known as johnny appleseed a guy who's said to have traveled on foot across the u.s planting apple trees had brought the apple to american folklore fame and by the 19th century americans by association had made the apple their own but apple pie was far from an american invention in fact the first recorded recipe for the dish was written in 1381 in england although it also called for figs raisins and pears not just apples where the phrase itself came from is a little harder to track in 1924 an advertisement in the gettysburg times promotes new lest suits that are as american as apple pie by world war ii it had stuck american soldiers would even tell journalists that they were fighting for mom and apple pie oh it seems like traditional apple pie is a classic case of a popular misconception there are actually tons of iconic things that aren't actually american including hot dogs rodeos and even american football can you think of any more popular misconceptions like these let me know your favorite misconceptions in the comments below and i might even get back to some of my favorites now where were we is there a dead wasp in every fig you may have heard this rumor circulating during prime fig season but it's not actually as crazy as it sounds you see figs aren't technically a fruit they're actually an inverted flower as we all know flowers need to be pollinated so they can reproduce and that's where the fig wasp comes in the relationship that is developed between the fig and the wasp is known as mutualism because both the plant and the insect need each other to successfully reproduce wind or bees can't pollinate female figs as they do other flowers but the female wasp knows how to get inside the fruit to lay her eggs as she squeezes through a small opening in the fig known as an osteo she makes the ultimate sacrifice as her wings fall off and the narrow passageway crushes her abdomen when she arrives inside she brings pollen into the internal flowers lays her eggs in the ideal environment for her offspring and then dies of valiant death the blind and flightless male wasps hatch first mate with their female counterparts while they're still inside their galls then burrows a tunnel out of the fig then the females fly out taking the pollen with them and starting the cycle anew so to answer this question yes there is at least one dead wasp in every fig but fear not when you eat figs you aren't actually crunching down on sacrificial insects the figs produce a special enzyme called physin which breaks down the wasps body proteins that get absorbed back into the plant somehow i don't know if i feel any better about that information do fish get thirsty your reaction to this question is probably you've lost your mind dude but it's actually worth considering the answer depends on the water the fish lives in freshwater fish don't drink much at all at least not like we do these fish have a higher concentration of salt in their blood and body tissue than in the water they swim in to drink they take small amounts of water into their bodies through their skin and their gills and then pee out any excess water the process that allows them to drink this way without having to consciously fill up on water like humans is known as osmosis they don't take much water in through their mouths if they did they would risk over diluting their blood and unbalancing the salt-to-water balance within their bodies but when fish live in salt water things are reversed because the concentration of salt in the water they live in is higher than the concentration of salt in their bodies in this case osmosis leads to water moving from their bodies to the water around them instead that means they are at constant risk of dehydration which is kind of ironic considering they literally live in water to compensate they must actively drink water through their mouths instead they process the water and then produce small amounts of salty pea as well as secreting salt through the specialized cells in their gills although they need to drink more than their freshwater counterparts saltwater fish probably still don't have a conscious response to seek out and drink water so the answer is something like this yes they get thirsty but they likely don't know it rabbits used to be used as pregnancy tests yes you heard that correctly before the trusty pee stick was around to determine your fate for the next 18 years or so there were innocent bunnies if you've ever heard someone use the perplexing phrase the rabbit died to announce their pregnancy in a movie or tv show here's why the bad news is the rabbit died its origins can be traced back to the 1920s and the discovery that a woman starts producing a hormone known as human chorionic gonodotropin or hcg shortly after a fertilized egg has implanted itself in the uterine wall seven years later medical researchers also found that female rabbits injected with urine containing hcg would within a few days also display distinct ovarian changes thus the so-called rabbit test was born along with the misconception that the rabbit's death was somehow an indicator of a positive result the truth is that the rabbits always died that's because the only way to detect such changes in the rabbit's ovaries was to open the bunny up and have a look around which inevitably killed it in the process modern pregnancy tests are still based on measuring the amount of hcg present in the urine but thankfully they do that directly now without the need for a sacrificial bunny the job of the best man at a wedding was to help kidnap the bride a couple of hundred centuries ago the role of the best man wasn't about throwing the best party holding the ring or making a speech with the most dad jokes in it his duty was actually to serve as armed backup for the groom just in case he was forced to kidnap his intended bride from her disapproving parents in fact the word best didn't even imply that he was the groom's best friend it just meant he was the best with a sword if a situation arose when it was needed the tradition stems back to a time where men were expected to take a bride from within the community if there was an inadequate supply of local women available eligible bachelors had no choice but to seek out and capture a bride from a neighboring community instead this also explains why the bride still stands to the left of the groom during the wedding ceremony because the groom had to keep his dominant right hand free for defense the original duties of the best man also took on a whole new sinister meaning the best man stood beside the groom until the wedding vows were exchanged to act as extra backup after the wedding he also stood guard outside the newlyweds bedchamber as a guard of sorts in case anyone decided to attack or the bride decided to do a runner suddenly the whole thing doesn't seem so romantic anymore could the t-rex really not see you if you didn't move if you've seen jurassic park you'll remember that one scene where the giant t-rex is attacking a jeep during a thunderstorm and paleontologist dr alan grant shouts don't move he can't see you if you don't move well i hate to break it to you but that claim isn't exactly airtight in fact this fearsome predator couldn't only see just fine regardless of whether an object was moving or not there's also a fair bit of evidence to suggest that its eyesight was better than modern day hawks and eagles after the movie's release in 1993 professor kent stevens from the university of oregon decided to get to the bottom of things he began the project dinomorph which aimed to create tangible digital visualizations of extinct animals including the t-rex north america's leading paleoartist garfield minot provided stevens with a lifelike t-rex head sculpture he'd been working on using this model a laser pointer a glass plate and taxidermic glass eyeballs stevens performed experiments to determine the visual field depth perception and binocular range of the t-rex for those who don't speak nerd the binocular range is basically the area that can be viewed at the same time by both eyes at the end of his experiments stevens concluded that the t-rex's binocular range was 55 degrees which is even wider than a hawks according to his findings the t-rex also may have had a visual clarity up to 13 times better than a modern human for some perspective an eagle has about 3.6 times the visual clarity of a person basically standing still is not going to stop you from being eaten whole by a t-rex there is some debate about how fast they were though with most scientists thinking they had a max speed of about 17 to 25 miles per hour so getting inside the jeep and flooring it is your best bet there's a real-life pun disorder we all know someone who can't help cracking terrible puns at every opportunity but what if i told you they might actually be suffering from a debilitating pun disorder known as vitulsut one of the first noted cases of this pathological joking emerged in the strangest circumstances by the german neurologist otfried firster in 1929 firster was operating on a male patient to remove a tumor the man was conscious a common practice at the time and at the moment firster started manipulating the growth his patient suddenly erupted into a manic flight of speech as he recounted pun after awful pun in the same year psychiatrist abraham brill reported coming across patients who would joke about anything and everything even when they weren't on the operating table since then many more cases have been noted strangely enough none of these jokesters seem to find other people funny despite considering themselves to be absolutely hilarious the link between those who suffer from vitso suit seem to be some sort of prior damage to the frontal lobes which could be caused by a stroke or a brain hemorrhage scientists believe that the network of regions around the frontal lobes are responsible for the same sort of complex analytical thought that is required to understand jokes the brain damage suffered by those with vitsosut seems to disinhibit some of the signaling between those frontal lobes and the pleasure centers responsible for making us laugh that means they don't find other jokes funny while their own thoughts and feelings might still trigger the dopamine kick which makes them giggle at their own puns i think it's high time i got myself checked out for vitsel suits why are cashew nuts not sold in their shells as we now know cashews grow on trees inside of fruit it's a lot to take in i know technically speaking the cashew fruit isn't really a fruit but rather the swollen end of the stem just above the cashew nut the nut itself is actually a seed inside the pit of the fruit which grows from the bottom of the apple as you can see here once that part is removed there's still a hard shell to get past before you reach the part that we actually eat you probably never know any of this because all those extra parts have been removed before the tasty nuts reach your snack ball but why aren't they just sold inside their shells like pistachios it's not just done that way to make things easier for you another thing you probably don't know about cashew plants is that they belong to the same family as poison ivy and poison sumac the plant contains a powerful oily chemical irritant called urushiol which can cause itchy skin reactions in people who are sensitive to the chemical this toxic fluid isn't only found in the leaves of the plant but also between the shell and the cashew nut itself once they've been harvested the seeds are roasted at high temperatures to destroy the harmful shell oil this is also when the nuts change color from a greenish gray color to the golden brown color we know and love if cashews were sold in their shells people would run the risk of ingesting the toxic chemicals in such large quantities that it could even prove fatal why do cats lay on their back when they see you throughout history cats have been thought of as mystical creatures and they still baffle us to this day one of the biggest mysteries of their many quirky behaviors is why they lay on their backs whenever they see you our feline friends express themselves through body language all the time but their signals can sometimes be hard for owners to read most of the time laying down on its back is a surefire sign that they're comfortable and happy in your presence when a cat exposes its belly it's leaving itself in a vulnerable position which usually means they feel safe and protected around you according to cat experts having their ears pointed up and facing forward at the same time could mean they're feeling in a playful mood they're trying to convince you that they're harmless so why not grab their favorite toy and try to instigate a game but there could also be a darker meaning to why your cat lays on its back in fact some have even suggested that it might be a sign of aggression this could also be seen as a defensive pose because your cat could attack with all four claws if their ears are flat back against their head your maggie is most likely feeling defensive and ready to launch an assault to be sure check their eyes if their pupils are dilated that could be a telltale sign that they're feeling agitated basically make sure to check the signs before you go straight in for that belly rub why don't insects get fat here's a life-changing question for you when was the last time you saw a fat bug and i don't just mean a plump looking caterpillar i'm talking a morbidly obese ant or a butterfly that could barely shift its weight off the ground there's a reason why you don't see chunky insects as often as you see plump people just like humans bugs can be overfed but being an obese insect has harmful effects males can't protect territory since they're more sluggish than their competitors they struggle to find mates and they generally don't live as long but truly fat bugs are still few and far between although insects can build fat reserves they rarely ever look fat that's because their outermost layer known as the exoskeleton is a hard protective shell that doesn't grow or stretch like our skin does when we get bigger insects don't shed this layer when they reach adulthood so fat just builds up underneath and puts pressure on the insides you can think of it like a victorian ladies corset that holds everything in place although some bugs might look fat like a plump caterpillar that spongy squishy texture is just the nutrient-rich storage the larvae needs to turn into a butterfly during metamorphosis anyone know where i can get myself an exoskeleton in time for thanksgiving who is luke in lukewarm the word lukewarm is normally used to describe the temperature of something but why not john warm or sharon warm more specifically lukewarm is a temperature that's neither particularly hot nor cold it's tepid if you like but it can also be used in other situations let's say you crack a joke in front of your pals and only get a laugh or two you could say their reaction was lukewarm but who or what is luke and how did the word come about the word luke actually comes from the middle english luke which in turn was borrowed from the dutch word luke meaning tepid or weak since tepid basically means barely warm there was really no reason to add the word warm after it for a long while luke was the standard word used to mean warm until the word lukewarm popped up around the 14th century to describe something as tepid and within the next two centuries it also took on the more figurative meaning of lacking in enthusiasm it isn't clear where the word luke as a first name came from but it received a huge boost in popularity thanks to the publishing of the gospel of luke around 70 to 90 a.d anyone else still prefers sharon warm or is it just me which of these mind-bending facts impressed you the most if you're not quite done packing your noggin full of random trivia why not go ahead and binge the rest of the series thanks for watching guys
