Why do some websites don't open without "www." when most websites don't need that? | **Pre-emptive tl;dr: There's no reason that www needs to be part of a domain name, it just exists as convention. Usually they point to the same place as the primary domain, but sometimes not. Sometimes it doesn't exist at all.** Website addresses are basically just a fancy shortcut to an IP address, at first they were ... |
Why can't we move our toes independently like our fingers? | Human here: You can, it's just harder. Your fingers are easier to move because they have 3 bones connecting them to your hand but your foot only has 1. If you try hard enough you can move only 1 toe at a time. At least I can. |
What is the financial benefit to EA for not selling games on Steam? | Valve takes a ~30% cut of every game sold on Steam. That 30% is a whole lot of money when you're settling millions of every game you put out. It's so much money that the expense of creating and maintaining your own distribution platform STILL saves you money. |

Why do human bodies build up tolerance to alcohol/drugs but not daily medications like antidepressants/cardiac/etc meds? | I can't speak for the other meds, but you absolutely can build up a tolerance to antidepressants and painkillers and the like |
We make leather from cows, sheep and pigs. Why not horses? | We can. A horsewhipping is not just an expression. The other animals are food animals. While horses are eaten, they were a delicacy for stone age people, horses are not meat animals the way the others are. The other hides are products of food production. Most likely an old horse is an old friend and just buried. |
Why is it so much harder to read a phone when someone else is holding it, as opposed to when you are holding it yourself? | We can't hold our body completely still. When you're holding the phone yourself, it moves together with your body - your movement is synchronized with the phone's movement. When someone else holds the phone, that's no longer the case - the phone swings together with the other person's body, not with your's. |
If 'white' and 'black' are politically correct terms for Caucasian and dark-skinned people, how come using 'yellow' and 'red' to describe Asians and Native Americans is considered offensive? | Because black was used less as a derogatory, and more as a descriptor, maybe? For the record, in social activism circles, the politically correct term to use is "people of color", or POC. Not "colored people", but you put the person first with "person of". Yellow and red as descriptors have also been used in more derog... |
Is "quark" really a nonce word? | It is a type of cheese, but the name likely comes from Late Middle High German. So it could have been a nonsense word *in English* at the timeELI5 Where the hell does "nonce" come from?Quark, in Germany and other German-speaking places , is like a soft cheese made from curdling milk and straining it. When Joyce used it... |
What happens to my iris when my pupil dilates? Where does it go? Does it compress? Is the pupil in front?? I must know!! | The pupil is the hole; that's like asking if a donut hole is on the front or the back of the donut. The iris is a muscular ring -- the "donut" -- which just gets "squished" into a thinner ring when the iris dilates, it's still there, it's just smaller, which causes the pupil to get bigger, because it's the hole in the ... |
How does your body know the difference between sleeping and napping? (i.e. when you nap, you wake about in a half hour or hour as opposed to a full sleep) | Waking up from a short nap or a full night's sleep depends on your body's [sleep cycle] which lasts about 5-6 hours. It takes about 45 min to enter deep sleep, and once you do, you are very likely to stay asleep for the full cycle. However, during the first 10-30 minutes, your body is still transitioning form awake to ... |
why do humans love spicy food | The molecule that causes the sensation of spiciness is capsaicin, which binds to the nerves responsible for registering heat and more importantly pain. This causes these nerves to fire, making us feel these sensations. In response to pain, our bodies release endorphins, which help to nullify the pain and create a mildl... |
How is it that Singapore, UK and the US found Nestle India's noodles safe to eat, but India found the opposite? | There's a possibility Nestle manufactures the noodles differently for exporting to countries which are more stringent with their checking. However, there's also the possibility that it was a shakedown by the government, possibly due to some bribe that Nestle refused to pay. That's the sorry state of politics around her... |
What's the reason pirates are depicted wearing eyepatches? | The fact that some pirates wore eye patches most likely had nothing to do with a missing eye, and everything to do with being able to see—specifically, above decks and below them. Jim Sheedy, a doctor of vision science and director of the Vision Performance Institute at Oregon's Pacific University, told the Wall Street... |
Why are so many freekicks in professional football/soccer shot so badly? | Perfection is what they are going for. They are aiming for the very edge of the net, the furthest distance from the goal keeper because anything aimed in the middle of the net is easily going to be blocked. Being just a little bit off will cause their shot to miss the net but missing a little bit the other way is no di... |
Why can most people cross their eyes easily, but not point them in opposite directions outward? | Because when you cross your eyes, you move your focus points closer together, and that has a function for seeing things close up.Seeing as far as possible will require your eyes to be pointed somewhat straight forward, not outward.The reason we can't move our eyes in different directions like chameleons is that our big... |
Why is a big screen that is far away more pleasant to watch than a smaller screen closer to your eyes (which covers the same space in your field of view)? | Your eyes can tell how far away objects are, especially if they're only a few metres away. This messes up your feeling of immersion so TVs don't feel as realistic as a cinema screen. VR headsets use optics to avoid some of these issues. |
Ghost in the Shell - Free Will | Well it is perceived on a delay of around 4 or .004 nano seconds for a brains command to be active. For ghost in the shell, she is constantly getting upgrades to help with a sense of phantom limb pain that she has randomly. Due to the fact that she was a fetus at the time of augmentation her brains wiring and impulses ... |
single camera vs multi camera setups for filming TV and movies | Multi-camera is often used in sitcoms. It's a cheaper way to shoot the show because you have multiple cameras filming things. Single camera is just what it sounds like -- just one camera. If you have a scene where you see three different camera perspectives, that means they re-positioned the camera for each perspective... |
Why do I hear so many radio ads for companies hiring truck drivers? | It's because truckers spend a lot of time on the radio The marketing ppl did a study and found out that truckers spend a lot of time on the radio so they put their ads targeting truckers on the radio The problem is that truckers don't listen to the radio, the radio they spend so much time on is their CB radios. Since t... |
Is there a condition that causes temporary super normal hearing? | Any particular triggers? I get something like that occasionally, but usually in a situation like being in a very quiet house and trying not to wake people upThat sounds like a [migraine] which can sometimes cause [over-sensitivity to sound]. Some people never develop the headache which is typically associated with migr... |
This may have been asked before but: How do radio waves travel in space? | So if you think of sound traveling, it is using some kind of medium or material. It moves the molecules and they hit each other. When you hear something it is actually the pressure of the air changing minutely.In space, however, sound cannot travel. This may be where you get caught up. Light, however, travels very nice... |
- Why did a downgrade of the US Gov't lead to more people buying treasury bonds? | I posted an answer already, but I forget to explain it like I would to a five year old. Say your friend owns a lemonade stand, and wants to grow. He tells you how at the moment he is making $10/day. He says that if you give him $20, he will make you part owner and give you back $2/month and you don't have to do anythin... |
What are the cultural and social reasons to throw a sexual bachelor/bachelorette party? | Bachelor parties date back to ancient Sparta, where where men would eat and drink the night before a friend's wedding. That was all about celebrating the union, saying goodbye to the 'carefree' days before a man took on the responsibility of a family, and swearing allegiance to one another for battle and stuff. I think... |
Would an object fully submerged in water be considered wet? | This is more of a philosophical question than a chemical one. What makes something "wet"? I 'd say that objects that don't absorb water can't be wet, but surfaces with water on them are wet. So a caught fish can be wet , or a person can be wet, though when we say that we really mean their skin. However, the word loses ... |
Does it take more energy to heat things up or cool them down? | Assuming your question implies that heating things is raising them higher than the room temperature and cooling them down is lowering them from the room temperature. The second law of thermodynamics says that you cannot transfer heat from a cooler body to a hotter body without some additional work involved. So if you w... |
What is the likelihood of a US economic crash and how likely is it? | Here's what you have to remember: we have *real* wealth. I don't mean numbers in a computer. I mean real, tangible things: strong houses, excellent roads, high-tech factories. We have a very skilled workforce. We have farms that produce tremendous amounts of food per square foot. We have incredible technology. That's n... |
Why do commercial airlines rarely have accidents whereas private jets and planes are frequently involved in accidents? | Because the commercial airlines usually have the stricter training requirements, the higher cutoff point and their pilots fly even more regularly. |
What are pressure points? Do they work like they do in movies? Can you really disable someone by tapping or pinching specific places? | Best I can tell they are nerve bundles, and yes you can. Generally, it's not a 'incapacitate' but rather can cause intense pain which most people react to. Some people you, can it fact hit them and they can take the pain. |
Why do some drinks need foil seals bellow their caps and others don’t? | If you can open the lid/cap and replace it without out someone knowing, it needs a seal underneath. If the lid had a plastic piece that breaks, or you have to rip a wrapping to get to it, it doesn't need a seal underneath. It's all about whether you can detect tampering or not.Drinks with foil seals aren't carbonated. ... |
Why must our vote for president have to be private? Wouldn't E-voting be alot easier if we didn't care who saw? | The challenges with e-voting have nothing to do with preserving the secrecy of a voter's choice. Also the reason to protect that secrecy are very important. Being forced to reveal your vote can lead to voter intimidation which is disastrous for democracy. It might seem counter intuitive because so many people openly sh... |
Why there's a shadow of heat, but I can't see it with my eyes? | The reason you can't see heat is because it is emitted as infrared radiation which has a much higher wavelength than the eye can pick up. The heat waves you see and this shadows are caused by the varying density in the air. Hot air is less dense than cold air. Fact. As light passes through air, we don't see any refract... |
How do mail-in rebates work? | The benefit is the perception of a deal. Only a small percentage of the consumers follow through on. So many times a consumer will purchase something with a mail-in rebate and either be too lazy or forgetful to go through the steps of mailing it in. So, while the company has offered the money back to all, it only has t... |
When scientist clone animal the clone is fully grown up or is it start as a baby and then grow up? | The animal starts as a baby. They aren't cloning the animal in the science fiction sense where they make an exact duplicate at the same age - what they're doing is creating a new animal embryo with the exact same genetic code as the one they're cloning. The result is that when it grows up, it's identical to the first o... |
Why does it get harder to remember new things when we get older? | It's more about conflicting information than about storage. Using your example, when you use a language 24/7 for 20 years you get used not only to its words, but with its structure. When you try to learn another language, you'll have to devote some time learning to not use what you already know. Things get weirder when... |
How do popular highways get backed up even though everyone is going in the same direction? | The volume of vehicles is the biggest issue. Only so many cars can travel on a given lane in a given time period before the car spacing is too close for the perceived comfort of the drivers. That gets compounded by lane merges, exits and entrances.The problem isn't the traffic on the highway, it's the traffic entering ... |
From a psychological/sociological perspective, why does it bother us so much to be ignored or to feel like someone forgot about us? | Humans are by their nature a social animal. We evolved to be clawless, fangless, and not that strong. We are intelligent and work together in a group to cover over our weaknesses. Humans are basically a herd animal, and we derive our security from that herd. From our community, from our friends, being a part of that is... |
Why do numbers in digital clocks jiggle when we chew something crunchy? | The digits are multiplexed. That means that each is driven in turn at high brightness for 1/6 of the time. Then the next one is turned on and so forth. It isn't normally noticed but sudden movement causes the on/off cycles to be noticed as your eyes get a slightly different image position each time. Multiplexing is use... |
Why do Flights from NYC to China go North above Alaska then back down, rather than Bee line to China | Because that's the shorter route. Flat maps sometimes don't do a good job of representing a spherical earth, especially at the poles. If you look at a globe, you can easily see that this is true.The earth is a globe, not a flat map. The northerly route is shorter when drawn on a sphereBecause that curve on the map is a... |
Why does tap water from the kitchen sink taste slightly different than tap water from the bathroom sink, despite having the same source? | First step is a blind taste test to see if the effect is real or only in your head. Get someone to fill two glasses, one filled from each source. Then see if you can identify which glass was from which source. If there is an effect, repeat it at other people's houses to make sure that it isnt your house's pipes specifi... |
How is this new forged carbon stuff stronger than traditional carbon fiber? | Without going and reading about this 'stronger' typically means a specfic type of strength - how hard you have to pull on both ends to tear it. In which case an obvious example is plastic. Plastic polymers look like a heap of tangled worms at an atomic level, and this gives them much more of a specific type of strength... |
What is the benefit of "pre-purchasing" a game? | PC games: if the game is bought on Steam or some other DRM manager, the game is downloaded beforehand and installed, and the game is ready to be played the very minute it is released. Console games: games bought in store have the possibility of being sold out before you have the chance to buy itit, even if you go in on... |
can current events in Ukraine be considered a genocide? | It's not applicable to groups of the same ethnic background, but that's not what Russia alleges. Although Ukranians and Russians are related peoples, they have since diverged into separate ethnic groups. Russia is claiming that the ethnic Russians within Ukraine's borders are being subjected to genocide. |
Why do men have nipples | Its simple. The default human state is female, so when the fetus is in the womb, it starts developing as if it was a female, and builds nipples. Only later do male hormones kick in and build decidedly male structures. There is no real evolutionary advantage to NOT having nipples, and they don't cost that much to build,... |
why do churches and cathedrals need buttresses but not skyscrapers? | Cathedrals are made out of stone, so it isn't easily self-supported. The wall can't support much more than the weight of the wall. Also, the walls are individual stones that are loosely mortared together . The extreme weight of the roofs pushes outward against the walls, rather than straight down. Without a buttress ro... |
How can an electron emit x-rays? | Electrons orbit the nucleus of atoms, they can change how far their orbit is, but they need to change how fast they are going. To slow down and get closer, they need to get rid of energy. When they get rid that energy, the energy leaves in the form of a photon . The energy put into the photon defines if its a radio wav... |
Can someone explain to me who typically chooses the codenames for military operations? | General: Why are you requesting 100,000 pairs of green tights!?Acquisitions Officer: It's for Operation Peter Pan sir, and it's top secret.General: I like the cut of your jib sergeant Approved! |
Why do most cakes and dessert recipes call for eggs? | In a cake, eggs act as a leavening agent, thus making cake light and fluffy. In baked foods like cookies, muffins, etc, eggs add moisture and act as a binder. I don't eat eggs, so I always look for the eggless version of things. There are substitutes for eggs depending on what you are baking.When a cake bakes, what's h... |

How does scam message stay open? | When you click the red X, you ask the program politely to close. It's supposed to be used so programs can clean up after themselves and save your work before they quit.

How can movies be remastered into HD when they were originally recorded in standard definition? | All "old" films are still saved on their original film reels. Film is actually extremely high quality and still better resolution than any current digital resolution. The original reels are scanned into computer files at a high resolution, nowadays probably at 4k , and the entire movie goes through the post-production ... |
Why do most foods taste completely different when hot or cold? | 1/2 of the time we eat, what we smell usually helps us define what we taste. If the food is hot, naturally it’s scent would be more present opposed to being cold. Try pinching your nose when you eat. Not the same exact effect but close. Also, you know. Your brain and shitSame reason when you heat something up it feels ... |
Are organs the same size for everyone or are they bigger for naturally bigger people and vise versa? | While there is some amount of variance, the average dimensions and weight of organs are the same throughout all of humanity according to a rough *height* metric. A 6\'5" adult male would have about 30% larger lung size than a 5\'10 adult male, assuming all other factors are "average". Fatter people will have heavier or... |
Why haven't we evolved to require less sleep? | Because that isn't how evolution works. Something we don't need anymore doesn't just go away as soon as we don't need it. Something better needs to come along to replace it. The people able to function on less work may be more successful in life, but it doesn't necessarily mean they will be able to reproduce better or ... |
What actually is snot (nose mucus)? | Your body is only really capable of producing a few substances, in different quantities so things like mucus, wax, sweat, semen, saliva, or milk tend to be made up of varying concentrations of salts, sugars, proteins, antibodies, other cells, and water.

What is the difference between Smiley Smile (1967), Brian Wilson Presents SMiLE (2004), and The Smile Sessions (2011)? | Pet Sounds isn't like SMilE in the least. But you'll probably end up liking it anyway. Go with The SMiLE Sessions. Pet Sounds is grounded in reality - SMiLE is a colorful fantasy trip. And hey. Try Sunflower. Also Friends. |
Debt as the dollar inflates/deflates | > Making another extreme assumption; this does not affect the economy significantly You can't do that, sorry. Such a marked deflation in the dollar would destroy the economy, pretty much a law of nature on that, which is kind of a failsafe in and of itself. The [1923 "hyperinflation" in Germany] is an example where hyp... |
Why words stop looking like words after you type them repeatedly. | _URL_0_From what I can tell, your brain recognizes the same word over and over again and gets bored.I would have thought it would have been the opposite to what these other redditors said: I think it's over-focussing rather than getting bored and moving on. Because the connection between a set of symbols and the semant... |
If it takes 3 hours for the sun to set in NY to LA, why doesn't the line of shadow move at 1000 mph? | I think you might be asking about the [**Solar Terminator**] which does move across the Earth at about 1000 MPH, but due to the scattering of light in our atmosphere the terminator line is not clearly visible on the surface of the Earth.The terminator does indeed travel at 100s of miles per hour ; you would be able to ... |
What is deconstructive criticism and it's role in group assessments? | It is when you just say things like "That's stupid and you're shit at everything" and it totally hurts morale and discourages peopleIt isn't the opposite of "constructive criticism". Rather, it's criticism which is done using the framework of post-structuralist theory. That is to say : it is the analysis of a given wor... |
If the same animal with different fur color is considered a different species, why aren't humans classified as different species based on hair color or other varying traits? | Physical features have nothing to do with being a species. Being a part of the same species is defined as being able to breed and produce offspring that can then produce more offspringThe same animal with a different fur color is not a different species. It is just different colored. All cats are from the same species ... |
The EU's Immigration Policy. Can EU Members Travel Freely Without Being Documented? | There are two factors to this: The Schengen area: A political agreement between a bunch of European nations that borders are open and no special documentation is required to pass over them. You can drive from the southern tip of Spain to Finland without ever having to present a passport. The EU : All citizens with a EU... |
How is it possible to track down the owners of illegal websites? | Unless they mess up and do something silly and self identifying. That's especially easy if the FBI or whoever can compel the hosting service to give them access to the server and plant some things to try and weasel identifying information out of the connection. Even with TOR you have to take a lot of additional steps t... |
How is point Nemo, a sea point which is the farthest from any land mass, calculated? | Here is how I would do it manually: For a start, much of the sea can be dismissed as a matter of course. E.g. the entire Mediterranean Sea is nearer to land than a point in the middle of the Atlantic Ocean. The next step would be to take a compass set at some set range and draw outlines from prominent points - Western ... |
Why do cabbage leaves grow rolled up in a ball where they're guaranteed not to get any sunlight? | Cabbage are artificially selected and bred. The wild cabbage leaves are not not balled up like that. In fact the cabbage is the same plant as broccoli and cauliflower. |
How are dogs bred for specific purposes? | Over generations breeders select for traits that make the dog better suited to a certain task. Your dog won't inherently know how to "rat", but will probably enjoy chasing small critters and he/she is physically suited to digging and pushing into small crevices/tunnels in which rodents may liveDogs have a lot of natura... |
Physiologically speaking, why do certain people react differently to marijuana? | There is *only* science to this, in fact. There are a few active components in marijuana. First is cannibinol, which produces the "stoned" effect: it is the depressant. THC is the most notable component. THC gets you \'high\'. It has a mild stimulative effect, and in large doses, hallucinatory effects. There are differ... |
How does Candy Crush recommend your next move? | This is haRd to answer because I don't have source code for it, but my guess is it does not know what is coming and it determines the "best" move by looking at all available legal moves and picking one by some method ', "Candy crush isn't recommending a best move per se, the game knows what shapes are on the board and ... |
why do car rental companies give you both sets of car keys attached to one keyring, where they can't be removed and used separately? | I feel like this is specific to the rental company you are using; cars I've rented have always given me two separate keychains :/ |
How do you get a second job? Are you supposed to keep the first one a secret? | When you got your first job, did they give you a time table on when you are available? You can usually change it . For the second job schedule time around the first job No not at all. You just go apply. You tell the second job that you are currently employed and where, and try to set your schedule around that. Of cours... |
How did early humans develop opposable thumbs? | Evolution does not work that way. It isn't as if some creature is sitting around thinking "this mutation woukd really help us" and suddenly his kids develop the mutation. The mutation occurred randomly and the environment was so that he survived while his non-opposable thumbed brethren did not. This meant he passed on ... |
Why are ships referred to as "her" or "she"? | Because it's mostly men who own them, they're super expensive, they cost a ton to maintain, and they're hella fun to ride.A lot of guys + a lot of water + no/few women = things become she/herSomething a lot of men are in charge of? Must be a femaleHonestly, anything that's in the transportation catagory or that is not ... |
How can acid eat through metal, but not a glass/plastic cup? | I'm not sure about the exact solution they are using, but I'm going to use aqua regia as an example. Solid metals are composed of metallic atoms arranged in a metallic lattice, with metallic bonds connecting them NOT chemical bonds. These are much weaker and can be sheared with less energy. Gold, as we know, is very un... |
the use and purpose of pointers in C. | The name is more helpful than people realize if you try to think of it visually. It's literally a variable that POINTS to something. So let's say we're playing hide and seek. John is hiding under a box. Sally saw John go hiding under there. Now I walk into the room trying to find John. I find Sally and say "Sally, give... |
What is an itch, why does it bother us, and how does scratching it make it go away / feel better? | Scratching an itch, releases endorphins instantly into the surround nervous system area. It provides instant gratification but ultimately makes the itch worse. Like smoking crack and getting an instant high but then coming down. I actually have no idea what I'm saying.Skin is usually itchy because of a foreign irritant... |
Why SSD is better than Hard Drive? | For one, they're faster. *Much* faster. Insanely faster. It's not even close. If you were to compare it to running, it'd be a bicycle vs a car. Additionally, SSDs can be much smaller in size, are more durable, and use less power generally. Much of this is due to physical HDDs' physical limitations. In a HDD, there are ... |
In baseball, why do they change out the baseball every time it touches the ground? | Balls covered in dirt are harder for the batter to see, which could present a safety issue when dealing with projectiles coming in the vicinity of player's faces at 100 mph. Dirty balls may also move erratically because of the uneven scratches and dirt accumulation on different parts of the ball. Getting rid of basebal... |
How do animals in eggs know when to hatch? | Genetic programming. Remember how you latched onto your mom's boob for your first meal? OF COURSE NOT. But you did, because it was genetically programmed that you had an instinctual latching-on process to get that milk into you . Animals are the same. They bust out of the egg when their genetics tells them it's time to... |

What is "Salisbury Steak" made from? And is it just a US commercially made food or does hit actually have roots in England? | Its roots are in the USA, not the UK. It's named after Dr. Salisbury who invented it in the 1800s. It's mostly ground beef but may contain some pork depending on who makes it. [Details.] There is a similar food in the UK, called a *grillsteak.*", 'I actually live in the medieval town of Salisbury England. You know the ... |
How come standard pixel widths (360p, 720p, 1080p...) correspond to the number of degrees in a/several full rotation(s) ? | It's the beauty of maths. The two aren't related besides the fact they both divide down really well. 360 divides by 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15 etc. As a percentage of these lower numbers that's way more than almost any other It's just simply that because they divide and multiply together so well they are so eas... |
Google's new parent company Alphabet? | In short, Google had become a huge sprawling company made of a bunch of brands, and Alphabet allowed to separate all those brands and make them independent from one another, while still having the same people in charge at the top. Google has grown to a point where they are no longer just an internet tech company. They ... |
How do movie makers hire actors to play 'ugly' roles. | Many actors of course find it insulting, but work is work, and getting acting work you gotta take what you can get, its hard.The actor might be a little insulted, but unless people are treating you poorly even when not acting, an actor will realize that it's just a role and nothing personal. Any half-decent director/pr... |
Why do download speeds between ISPs vary, even though they use the same phone lines | The factors affecting speed are: 1) ADSL: The distance between your home modem and the ISP's "DSLAM" . The shorter the distance, the faster the speed . 2) The brand, model and configuration of the end devices: Different home modems/routers have different limitations, likewise for the ISP's routers. 3) The amount of ban... |
Why is everyone criticizing the movie Stonewall? | The producer is being criticized for whitewashing the cast of the movie, as well as not putting and transgender people in, or really, any type of person other than a 100% homosexual white man. He claims that "back then" there weren't any transgender people among the population of those who were protesting . He also poi... |
What exactly creates this 'second' tide? | Because the moon and the earth aren't pulling each other like tugging a rope. They are falling towards each other but keep missing because they move forwards faster than they fall. The moon isn't just spinning around the earth while the earth stays still. They are orbiting at their center of mass. The center of mass of... |
What are chefs talking about when they're talking about acidity and adding it to food, and why does it feel like I can't taste the difference? | Acidity has a couple of uses in cooking. For one, acid breaks down other substances, helping to tenderize vegetables or meat for example. It initiates a chemical reaction. This is also the reason it is used on apples and some other cut fruits, because the acid prevents them from turning brown when being exposed to air.... |
What exactly makes that knuckle-cracking-sound? | When you release pressure on the joint, dissolved gases in the joint fluid expand. Then they immediately dissolve again and what you're hearing is the fluids "slapping" back together. So yeah, it actually is kind of like a bubble "popping." |
