How do they make all car keys for the same vehicle different? | For older keys they just didn't bother. For a typical house key, for example, you could have 5 pins with 10 positions each, meaning that there are 100,000 different keys. At that point the odds of getting a working key by random chance are so low that you just don't worry about it. For newer cars the keys tend to have ... |

Why putting a spin on things makes them travel straighter (e.g. rifling with bullets) | Like some have said earlier, a bullet fired without rifling, will just tumble through the air because a bullet doesn't have fins like a nerf football. To describe how the gyro part works: if you try and tilt something not spinning at all, it will rotate away from the force. If something is spinning really fast and you ... |
How do people make money on buying debt? | Its generally uncollected or defaulting debt in the cases you're talking about.

Why is is when glass shatters the broken pieces easily cut you, but when ice shatters, the broken pieces are safe to handle? | If the impact is fast enough or the edge is sharp enough or whatnot, ice CAN BE as sharp as glass. But you'd need some seriously frozen conditions for that too. In most humanly-accessible cases, the air around the ice isn't actually cold enough to sustain the icy condition, and so the first thing to melt is usually cor... |
Why is the sinking of the Titanic such a big deal in pop culture? | 1.) It wasn't that long ago that it happened. Up until a few years ago there were survivors still alive. 2.)

Also the majority of the people on ... |
Jupiters surface, or lack thereof | Planets are not defined as having a surface.

Remember when you were my age and you and your friends would meet up at the malt shop that... |
What is the science behind being able to take a punch? Are heads built that differently? | It's all in the jaw and neck strength. If you can keep the skull movement minimal you can lessen the damage.

How can a business like Planet Fitness choose who they do not want to join but it is not viewed as discrimination? | In the USA, only a certain set of people known as *protected classes* may not be discriminated against.

Why is Stephen Colbert under investigation for indecency by the FCC but every news agency or show that replays the clip isn't facing the same scrutiny? | Every complaint filed with he FCC generates an investigation. At this point,it doesn't really mean anything,just useless posturing. And in this case someone reported it.The news agencies are either beeping the word "cock" or they're being shown in places that aren't under FCC jurisdiction. Remember the FCC only covers ... |
How is it possible that a bomb can be dropped from a plane and hit the ground and NOT detonate? | Bombs have fuses and bits inside that need to function correctly in order to explode. They don't blow up by simply hitting the ground really hard. |
If some online stores use bitcoin as a payment method, are they obliged to pay taxes, since no 'official' currency exchange has happened? | [Serious] Now I have to ask, if someone gives me a doge coin or a fraction of one, like through the tip bots they have around reddit, does that count as revenue if I give it right back/can't use it for anything or don't believe it is worth anything? |
why everything is funny when I'm tired. | That's odd, I have the opposite. When I'm tired, nothing is funny. It's not funny, leave me the fuck alone, you're not funny, I'm crabby and exhausted. Does this mean my brain is broken, or more logical than I expected? |
what is the scientific reason why two first cousins shouldn't get married? | There is none, really. Contrary to Puritan-stained myths, it would actually take several generations of DIRECT inbreeding to see consitent issues. Look at the monarchs of Europe. They're inbred over CENTURIES and largely remain healthy individuals, though they are prone to certain conditions . The reality is that two u... |
Why do people forget so easily the good things you did for them in the past? | People do this because they don't need to worry about the problems you solved for them anymore. With today's society how it is, everyone has something worrying or stressing to deal with all the time, we jump from problem to problem and forget about what people have done for us. Dont take it personally", 'The Brain only... |
Why can my sleeping brain create a wildly imaginative dream with intricate detail, but my waking brain struggles to come up with a creative premise upon which to write a story? | All you will hear about 10 percent are bullshit. Your brain works more when you are sleeping than when awake. That's it.Apparently because your self-censorship or critical tendencies keep you from basing stories on your dreamsWhen you sleep, you are using much less functionality of your brain to process the information... |
Why are so many teenage boys obsessed with phallic imagery? | Hormones and immaturity combining at the wrong time. I had a girl on a team project in college that used to doodle naked chicks in sex swings, so maybe its only less common for women because the hormonal drive peaks after they're mature enough to know better._ // 7 /', "Well, boys go through a stage where they are very... |
How does space ships millions of miles away communicate and send videos to earth? | They send the data through radio waves. The same way you get data on your phone, only further away. As there isn't really that much stuff in space to block the waves, they can travel really far. We can detect radio waves from billions of lightyears away. |
Why are American police officers allowed to "bait" people into committing crimes (ex: bait cars, sting operations)? | If I hand you a gun and you choose to shoot yourself in the foot, that's on you. I didn't force you to shoot yourself, you did that entirely of your own free will. It is the same with police officers and bait cars. They aren't forcing you to do anything illegal, you're doing it entirely of your own free will. They are ... |
What is the difference between a rock band and a metal band? | It's a spectrum with rock bands on one end, generally adhering to softer distortion, more traditional melodic structures, and a broader appeal to the masses , and metal on the other end, more often using heavier distortion, down tuned instruments, and less traditional song structures with a lot of focus on percussive r... |
Why are female-female friendships often more difficult than male-male friendships. | Women are just more passive aggressive and almost everything is a competition. Like who is prettier, better outfits, cuter boyfriend, etc. It gets kind of superficial and annoying. I just can't deal with the drama. |
If sound travels faster in water than in air, why do we(I) here a muffled sound when swimming? | Though the soundwaves are transmitted faster in water, there's more particles in their way that they have to travel through, so the soundwaves are distorted and made hard to hear. Whereas, in air, soundwaves pass through less particles, and end up being received less distorted by your ears. The same thing is the reason... |
Why is it that you can download pirated music that is higher quality than what you can purchase from iTunes? | Becuase iTunes is *a* source for *some* music, but by no means *the* source for *all* music. Think of iTunes as the convenience store of online digital music vendors - everything there is marked up slightly in price relative to the same sorts of products when they appear at other kinds of vendors, most things are sold ... |
Is it possible to eject out of an airplane that is breaking the speed of sound, and live? | I can't remember where, but I deffinetely remember being told you experience 200g when you eject, and 800g because of how the air acts at that speed!

How do employees of marijuana dispensaries in the US handle their taxes if their income is based off the sale of marijuana? | 5 year dispensary manager here. To answer your question, we handle it normally. I filled out a w2, and taxes are taken out of my check every time. I get an income tax check every year like normal. We have an account with ADP and have to just keep money in our account with them. One time the owner forgot to deposit fund... |
How come alcohol triggers hunger even though its caloric itself? | I imagine it's for the same reason appetizers exist.

Your tummy doesn't like being full of acid without... |
What does crossing the CO2 levels crossing 440ppm mean for the rest of us? | So, it's not has horrible as many make it out to be.

The US sought to contain communism to ... |
Why can't popular vote be what decides elections in the US instead of states going left or right? | To start with, keep in mind you're only taking about presidential elections. Almost all of the elections don't work this way, but the Constitution is set up so that the president is elected by the states. This is useful, because it means the federal government doesn't need to run any popular elections--only the states ... |
Why does 66 degrees outside feel very nice but 66 degrees air conditioned inside feels super cold? | I'm from south Texas and I absolutely think that both 66 inside and 66 outside are VERY cold. |
Why does my dog hate being wet from the shower but doesn't care about being wet from swimming | Swimming is wide open and the dog gets to move around on his own. Showers are generally in a confined space plus you're generally trying to hold him/her still so you can wash him. Why do kids enjoy going to the pool but sometimes hate taking showers? Same reasons most likely, it's not about the wetness -- one gets asso... |
What would happen if CO2 levels became "too low" in the atmosphere? | This may happen in the far future . CO2 levels naturally fall via weathering and CO2 is naturally emitted from volcanoes. Without people around these two are in a pretty nice balance. But in the future plate tectonics will stop and the volcanoes will stop emitting CO2 and weathering will bring CO2 levels way down. So w... |
What is the purpose of the short pillars or concrete spheres outside of stores like Target or grocery stores? | More likely it's to keep thieves from driving into the store, grabbing all the merchandise they can, then driving off. That happened fairly often in Houston, TX, in the early 1980s. |
Why Reddit gold is such a big deal. | Someone gave it to me over on /r/Dota2 by random happenstance. It isn't anything special tbh. I don't even realize I have it still. |
Why do shirts have collars? | It's there to hold the necktie in place. Why do we still wear neckties? Relentless lobbying by the cunning and ruthless necktie industry.

Why were only dinosaurs wiped out when the meteor crashed and the atmosphere changed? You never hear about other animals or other forms of life going extinct in this time period. | Part of that has to do with the fact that people believe dinosaur refers to any big animal living back then. It really doesn't. Dinosaurs were a very specific group of animals. [This animal] ? Not a dinosaur. [This awesome bastard] ? Also not a dinosaur. So already when people say 'the comet wiped out the dinosaurs' wh... |
How the Hubble telescope transmits live info to earth | The Hubble isn't moving away from Earth, it's in orbit. The images it transmits aren't exactly live, there is a transmission delay. |
How are some artists able to paint very simple paintings and sell them for a lot of money, but if someone else painted the same painting it would be worth almost nothing? | Being the first to make something is also a big part of it. Anyone can copy someone else style, but it's not original.For very simple "abstracts" or geometric shape paintings, it can be because the artist is a good huckster and managed to convince a very wealthy patron that their simple drawing was high art. The reason... |
Products like Cutco and Kirby Vacuums are actually great, but why do the companies sell them in the shittiest way possible? | A JA Henckels knife that cost $100 for you or me to buy at Bed Bath and Beyond is sold to that store by Henckles for about $50. So Henckles makes $50 and has to buy the displays and all the marketing collateral for The store. Cutco sells a $100 knife and will typically pay their independent sales person on average mayb... |
What is that feeling when one looks at a ants, spiders, rats, snakes? | It's kinda fear. It's in our genes to be creeped out by stuff that can be a danger to us. Our ancestors are the ones who were creeped by spiders. The ones that didn't feel that feeling didn't think to not go touching or eating the danger, thus dying out. It's bred into us, an inherent wariness of creepy crawlies. They'... |
Monsanto's patent on broccoli | In effect, Monsanto's patents are similar to patenting software. The are patenting a small amount of instructions for getting a plant to grow. They do not patent the entire computer, nor do they patent the operating system. That is to say that they do not patent the entire plant, nor do they patent the bits core to a p... |
Why is lethal injection seemingly so complicated? | Here's the thing: lethal injection only really exists because we are constantly trying to turn state-sponsored and formalised killing into something clinical and procedural. That's why basically all other changes in method occurred, like the guillotine, gas chamber, electric chair-we want something that looks cool and ... |
Why does the etymology of so many words stop at the Latin origin? | There were definitely languages before Latin, but Latin is pretty much the granddaddy of western languages that we know today, influencing french, english, italian, spanish, portuguese, and others because of how far the Roman empire stretched. You also have to consider that Romans were also really really good at preser... |
Why don't men have to worry about the amount of mercury they consume from seafood, but women do? | Mostly it is an issue of pregnancy. Mercury and other heavy metals stay in a person's body for life. If a woman eats large amounts early on, and then later has a baby the foetus will be exposed, causing problems. The younger the person is when exposed the larger the problems from heavy metals. This is why children and ... |
why it feels so fucking good, like borderline orgasmic, to go take a piss when you're drunk? | While on the topic of pissing and alcohol. Does anyone enjoy pissing outside more than usual when they're drunk? |
Why can't the south drive with even a little snow? | A lot of places in the south get snow very rarely. Therefore, people have very little experience driving in it. Do you really expect people to be good at something when they have zero experience? Also, some cities/states don't invest much in snow plows or salt trucks. Why would they? Economically it's easier to just sh... |
Why hasn't anyone made women's pants that have functional pockets? | People do. For example, there's a store not far from my house that sells hard hats, jeans, traffic vests, etc that are affordable and rugged. I'm told that their womens' jeans have pockets that are like normal pockets, because everything in the store is designed for cheap utility. In general, women are taught to shop a... |
Why is the Mona Lisa so widely regarded as the most famous painting of all time? | Sort of like how everyone knows Kanye West but they aren't really sure why or how. It just always appears in the media and just kind of gets imprinted in your mind. |
What qualifies as a tax write off, and is it possible to avoid all federal taxes with tax write offs? | You need a proper tax accountant to get proper advice. Basically, if you incur an expense that was necessary for you to earn your income, you can subtract that expense from your income for tax purposes. If you earned 20000 as an artist, but spent 8000 on materials, you declare your income and 8000 deduction and your ta... |

Why do we sometimes sweat when we aren't hot or exercising? | Heat is continually lost from the body by evaporation from the skins surface even when there is no sweating and sweating is effective only as long as the sweat is evaporating. Evaporation is dependant on a few things such as the pressure gradient between the liquid and the environment. If the pressure difference doesn'... |
Why is it bad if firearms overheat? Why do they stop shooting? | Metal changes shape when it's hot, and it gets soft. Bullets have a lot of energy behind them. If the barrel is too hot, the bullet could stick in the barrel, burst the barrel. The cartridge could burst in the magazine. None of this is good. |
How does a human cell work? | I mean, you could take a semester long course on the functionality of different parts of a cell and how they work together to allow the cell to perform particular functions. Unless you have a more specific question, this probably isn't something that is ELI5-able. |
Why is Iran perceived to be a greater threat to the US than other countries in the middle east like Saudi Arabia? | Only one middle eastern country has stormed a US Embassy and held US diplomats hostage for over a year with the constant threat of them being lined up against a wall and shot, and it sure as shit wasn't Saudi Arabia. Iran was lucky that Congress didn't declare war over that. |
Why can't GPUs reach core clocks speeds of 4.0Ghz+ like CPUs? | it's not that they can't. It's just not worth it. It wouldn't make the GPU faster. Each GPU core would be vastly more complex and much, much bigger than it is today. For the kind of workloads a GPU is designed for, it is much more efficient to have hundreds of fairly simple cores than having 20 hyper-complicated and bl... |
Why doesn't Netflix offer Blueray quality video? | Netflix has to pay for outbound bandwidth. Sure, they get a great deal, but it still runs fractions of a penny per gig. Usually like 3/10ths of a cent or whatever. They'd have to raise prices to stream 25 gigs or more for each movie. Bear in mind, even if Netflix does not actually pay per gigabyte, they still pay per g... |
Why do you die when you're shot? | Many times, it boils down to blood loss. When it involves a head shot, it has to do with severing the spinal cord or damaging important parts of the brain, which in turn stops the heart and breathing and all the stuff that keeps you kicking. Impact with the spine at certain levels can cause the same results. Shots to t... |
Why is fresh yellowfin tuna $24.99 lb and canned yellowfin tuna $6 lb? | Canned fish can be stored unrefrigerated for a long time. The increased overhead from overnight shipping fish and keeping it cold adds to the cost. Plus, there's the added cost of spoilage if you can't sell enough of it fast enough. |
Bees, wasps, hornets, yellow jackets, etc. | Bees: Pollinate things. Give you fruits and vegetables, honey. Plants can't live without bees. Wasps: Most of them are solitary and hunt and kill other bugs. Including spiders. Mud daubers, for instance, paralyze spiders, bring them to their nest and feed them to their young. So wasps are good too! Hornets: Nasty littl... |
Why is the general consensus that Canadian health care is better than American health care | The quality of care in the American system is better overall than in Canada. The difference is in the costs and insurance model. For the most part, if you work full time and you aren't doing entry level work there is a good chance your employer will cover a good portion of your insurance costs. You should also pay less... |
How do modern warplane dogfights work? | They don't dogfight like in the movies. It's done nautical miles apart from each other. Evasive maneuvers are countermeasures and machine guns are guided missiles. If it's truly one on one, the fight is over long before either plane is actually hit. |
Why are names in a directory sorted by last name instead of first? Example: Lincoln, Abraham instead of Abraham Lincoln | It makes more sense to have all the Lincolns grouped at the same page of your directory, because they are certainly linked together, than having all the Abrahams grouped which doesn't help you in anything.Social interaction used to be more formal in English speaking countries. An equal would be Mr. Smith, and inferior ... |
How does adding volumes work? | A decibel is actually a *logarithmic* unit, meaning that each ten steps up the scale is actually a ten times increase in intensity. 20dB represents a relative intensity of 100 so if you added ten of those together it could reach 1000 intensity which is 30dB But really, there's a bit more going on than that with stuff l... |
The Price is Right did NOT give away 215,000 possible dollars today, so who gets to keep it? | Their production budget is 215k to the good today. Over time they know the average payout so they can smooth out daily variations over a year's budget, alongside all the other costs and incomes that aren't necessarily constant day-by-day. |
Why is it important to know the millionth decimal place of Pi? Aren't we accurate enough at some point? | Wanting to know more about π than the first couple of decimals has nothing to do with accuracy. It's about understanding the relationships between different mathematical constructs and how they behave under different operations. And what we want to know isn't really the specific decimals, but more things like whether t... |
how is it legal for restaurants to deduct pay of servers when patrons skip out on their check | It isn't but you'll get fired if you report it so its either get lose out on the price of one check or lose your job |
Why am I nostalgic about a time I didn't exist in? | Back to the Future never goes to the 1960s. It's 1955. But this might enlighten you: _URL_0_ |
Can someone explain to me what the whole issue regarding NHS in the UK is all about? | The NHS is free healthcare at a reasonable standard, which is very often compared to american healthcare expenses because they're so high. NHS having a child fee? Nothing. America? $75 million.You have to stay overnight? No problem America? $3000 Basically free public is good, expensive healthcare is bad |
Why does reheated food taste bad? | It doesn't, if you reheat it the right way. In fact, I actually prefer some foods the next day. Lasagna is so much better on day 2, freshly reheated out of the oven.My tongue must have some freaky tastebuds or something because I mostly prefer reheated leftovers over freshly cooked. Note: this does not apply to fish, h... |
How is it drones have more range than a standard RC vehicle? | It's hard to say without knowing what type of radio protocol the drone is using. Though the simple answer would be that they're using a low frequency high amperage transmitter. Where as standard RC craft use higher frequency lower amperage transmitters. |
Why can't the police or banks trace the money, when people are scammed through IRS or over the phone? | great you traced to money to Bulgaria. you make a call over to there. but by the time the police go check the records, it's already been transfereed out. to Mexico. ok you call that bank in mexico. sorry. it's gone already, it's in china. sorry it's gone already it's in canada. sorry it's gone already to australia. sor... |
Why is it not racist to have all black organizations? | This is definitely a very touchy subject. I'm not black, but I am mixed white and hispanic, and really what it comes down to personally for me is as long as the organization has a positive message and encourages education rather than inciting hate then i'm fine with it. There are all kinds of groups for different peopl... |
Why are some large batteries (like Tesla's) made up of smaller cells? | they're cheap. designing a battery cell from the ground up is very complex and expensive. so in order to save money and time, they use a which means taking available parts in market and designing using that and maybe adding some smaller custom components. which means in this case you take 18650 cells which are cheap an... |
why would Pi not be a rational number? If the entire universe can be expressed in mathematical formulas, why would such an important constant be so random? | The other users posting on this rightly pointed out that a number being irrational does not mean it is random. But for argument's sake, let's say that they are random. This question comes from the assumption that because the universe is governed by equations, it must therefore be orderly and rational. This is essential... |
- Why do we see better with our peripheral vision in the dark? | Your eyes are made up of cones and rods. Rods see more detail, however they can't detect colors. Cones are really good at seeing color and are grouped towards the center of our eyes. So my using your peripheral vison you use more of your more sensitive Rods, and sinces its already dark color is less important anyway. _... |
Why does McDonald's charge $1 for a small, medium and large soda? | By pricing all the soda sizes the same, it makes the medium look like a good deal. And if that's a good deal, the large much be a steal! Someone who was only going to get 2 McChickens might now also get a soda as well. Even people who were already getting a soda are also, happy to get a free upgrade to a large. Or just... |
Why do certain drugs (e.g. meth and heroin) make it seem like the user has aged decades in a short amount of time? | I know there are more technical things than this but addicts I've known stop eating properly, forget basic hygiene like brushing teeth regularly, don't drink enough water if any and don't sleep. Even if you don't use drugs the above will make you look like shit. |
Why did some ancient cultures accept homosexuality (examples, Greek, Roman) while others (example, Jewish) did not? | A large part of old-age/modern Jewish culture is about child-birth and keeping the tribes going. There were always a few number of Jews in comparison to other groups, which may be why the child-birth culture eventually originated. Therefore it may be safe to make the assumption that homosexuals lack of reproduction may... |
At what percentage alcohol does an alcoholic beverage hydrate rather than dehydrate a person? | From medieval times up through the colonial US, alcohol was the main beverage, so it must have been hydrating. They drank 'small beer' mostly and according to _URL_2_, that was 3-4% ABV. _URL_0URL_1_ |
What could go wrong to lead an electrical outlet to spew water? | Not electrical fault would cause that of course, but it does mean you have an issue. My first thought would be **turn off that circuit at the breaker immediately**. Is it against an outside wall? It could be you have a leak from outside that is making it's way into the box. Either way that is a safety hazard for sure. ... |
How did the clover become a symbol for the Irish culture when clovers are everywhere on the planet? | Saint Patrick used a shamrock to explain the Trinity. Just as the shamrock is one plant with three leaves, so God is one being with three faces. The shamrock was thus associated with Patrick; since he's our patron saint, he came to embody the Irish people, and thus by association the shamrock came to represent Ireland. |
Why is Japan widely known to have a xenophobic culture? Is it true and if so where does their xenophobia originate? | Well, because Japan is far less open to immigration than most other open, democratic societies. Xenophobia may be a bit of an exaggeration, but the Japanese government certainly heavily restricts who can live and work in Japan. This lack of openness to outsiders has deep roots in Japanese culture. For centuries prior t... |
Why do people get angry quicker when they're driving? | I'm going to answer for myself: there is a bunch of rules to follow when we are driving - all of them completely necessary to have an organized traffic. Not following any of them puts not only my life in danger, but everyone else's. That's a stressful situation: while I'm doing my best to be a good driver and follow th... |
Why doesn't all the gas in the Sun burn at once? How come it take few billion years? | The gas in the sun doesn't burn, it undergoes nuclear fusion. This process can only take place in extremely hot and dense places near the core, so thwe rate is very small compared to the amount of fuel in and around the sun. Also as fusion occurs the elements created will themselves also eventually undergo fusion.The s... |
Why do the religious believe the teachings of their God of choice without a single objection, but they won't believe anything else even if you gave them a mountain of proof? | It's taught to them by either those they love and trust most or people with authority over them. Also if you're willing to grant the belief in a freaking omniscient all powerful deity then suddenly something like a talking snake really isn't a big deal. Plenty of Christians just think that certain stories are allegoric... |
No shoes no service? Why not? | It's usually a liability insurance requirement, because a barefoot customer is more likely to cut or otherwise hurt their feet while inside the store. |
What are the problems with the current UK government? | Since this is a bit of an open question, I'll try to be as objective as possible. It would be easy to moan about the privatisation of British institutions like the NHS, but as I said, this wouldn't be at all objective. If there's a single issue that falls down on both the right and the left it's a general feeling of th... |
what makes a moon, a moon? | A planet is a very large mass that revolves around a star. A star isn't a planet; it's an extremely large ball of gas that creates heat and light from nuclear fusion. A moon is a smaller mass rotating around a planet. Sometimes moons can actually be *larger* than the planet they rotate around, but that doesn't mean the... |
Why Do We "Shake" Before Falling Asleep? | It's not totally sure which is the cause of this kind of movements . An interesting theory suggests that they are caused by the opposite mechanisms of two different deep brain structures: the reticular activating system and the ventrolateral preoptic nucleus . The first region normally exerts its effects on movements w... |
Why are uncooked eggs dangerous but sunny side up eggs are ok? Isn't the yolk uncooked? | The egg has its own mechanisms for preventing harmful bacteria from entering the yolk.
