Why is different kind of beers served in different kinds of glasses? | Much the same reason wine is served in different glasses. Glass shape and size changes how aromas are presented to your nose. Smell is a huge part in the taste of things. Hops is very aromatic and the type of beer has different volatile compounds from the type of yeast used in fermentation that affect the flavor and sm... | Different beers are served in different glasses mainly to enhance the beer's flavors, aromas, and overall drinking experience. The shape of the glass can help concentrate aromas, maintain carbonation, and even affect the temperature of the beer. Plus, certain glasses are designed to showcase the beer's color and clarit... |
Why does hydrogen peroxide make your skin itchy? | Hydrogen peroxide is quite a reactive molecule, commonly used as a disinfectant in low concentrations for cuts as it kills bacteria. It is also a really good bleaching agent. Unfortunately, hydrogen peroxide will also react with skin, especially in higher concentrations and can cause unwanted reactions. When these unw... | Hydrogen peroxide can make your skin itchy because it’s a strong oxidizer, which means it can irritate your skin by breaking down cell membranes and causing inflammation. When it reacts with your skin, it can lead to a mild burning sensation or itchiness, especially if you have sensitive skin or use a high concentratio... |
Why isn't there significant talk about forming a third party in the US during this current political climate? | One of the most robust conclusions of the literature on political science is that a winner take all voting system (like the US') will lead to the consolidation of political parties into two. Pretend there are two parties, L and R which are left and right wing respectively. I then start a new party named LoC (which is l... | Creating a third party in the U.S. is super tough because of the way our electoral system is set up. Most elections use a winner-takes-all approach, which makes it hard for third parties to gain traction since voters often feel like they’re wasting their vote. Plus, the existing parties have a ton of resources and supp... |
Why do my ears ring in a quiet room ? Is it psychological , scientific reasoning , or does this also happen in louder surroundings and just goes unnoticed ? Edit : thanks for the responses and explanations ! Please explain like I'm five. | It 's called tinnitus . You probably have a very minor case of it . It happens all the time but you do n't hear it for the same reason that you can hear yourself type on a keyboard in a quiet room but not if you turn on loud music . | There are a few possible reasons why you might experience ringing in your ears, or tinnitus, in a quiet room. One possibility is that you have damage to the hair cells in your inner ear. These hair cells help to convert sound waves into electrical signals that the brain can interpret as sound. When these hair cells are... |
Why do batteries lose their recharging ability over time? | Batteries are compact galvanic cells. They work by compartmentalizing a chemical reaction, in which one of the compounds is oxidized (loses electrons) and the other is reduced (gains electrons, I know it's counter-intuitive). Galvanic cells separate these two reactions so that the electrons that the oxidized compound l... | Batteries lose their recharging ability over time mainly because of chemical reactions that happen inside them. When you charge and discharge a battery, these reactions can cause wear and tear on the materials, leading to issues like buildup of unwanted substances or changes in structure. This means the battery can't h... |
Why do dogs and cats like to be petted ? My dogs love to be petted but why ? Seems to me it would be annoying to be rubbed all over all the time . Please explain like I'm five. | Human here , also like when someone pets me | Dogs and cats like to be petted because it feels good and helps them relax. Being petted releases endorphins in their brain, which are chemicals that make them feel happy and calm. Petting also helps to strengthen the bond between humans and their pets. It's not necessarily annoying to be petted all the time, just like... |
What is Obama's reasoning behind drones, and why can't the US just pull its troops out of the Middle East? What will happen? | Drones are typically used to target militant commanders in the hard to access tribal regions of Pakistan. They allow the US to conduct recon in the area for longer periods without the risk of losing a pilot. Drones have also been used in Yemen to target the growing influence of Al-Qaeda in the Arab peninsula. The US t... | Obama believed drones were a way to target terrorists without putting American troops in harm's way, as they could carry out strikes remotely and minimize risks to soldiers. Pulling troops out of the Middle East completely could lead to a power vacuum, potentially allowing extremist groups to gain more control and crea... |
Why do churches have such high ceilings ? I 'm not religious at all and it really makes no sense to me . Explain like I'm five. | Bigger the church , the more powerful it is perceived . It stands out among all the other buildings in a town ( historically ) . Sounds are amplified within the church ( due to other architectural features as well ) . Also , the arches that are used to support the large amounts of glass in the walls . Oh and I guess du... | Churches often have high ceilings for a few reasons. One reason is that the high ceilings can make the space feel grand and impressive, which can be fitting for a place of worship. Another reason is that high ceilings can help to create good acoustics, which can be important for singing and speaking. Finally, high ceil... |
Can someone explain why we have strict liability in law? | The reason for this is many crimes do not require you to intend to do something illegal, or have motive. For example the prosecution does not need to prove a drunk driver intended to drive drunk, only that he did in fact drive drunk. This idea of strict liability is usually only applied to minor violations, like parkin... | Sure! Strict liability is a legal concept that holds a person or company responsible for harm caused by their actions, regardless of intent or negligence. It’s often used in cases involving inherently dangerous activities or defective products, making it easier for injured parties to get compensation. The idea is that ... |
Why don't razor/shaving cream companies push for men to shave leg hair? Wouldn't that increase their market and profits? | There is also a risk of a backfire.. If they push it too aggressively, then the brand may be seen as feminine by a large part of the target group. As you might have noticed, portraying a macho image with male-grooming items is seen as important in advertising. | That's a good point! Traditionally, shaving products have been marketed mainly toward men for facial hair, and leg shaving has been more of a focus for women. It's partly due to societal norms and expectations around body hair, which can vary by culture. But you’re right—if companies started promoting leg shaving for m... |
AM vs. FM What does AM radio and FM radio stand for ? What is the difference between the two ? Why ca nt there just be more channels instead of two separate radios ? Explain like I'm five. | You understand writing , like news papers , or the notes mommy leaves dad or mommy ’s girlfriend , yes ? And you understand that instead of those symbols we see with our eyes , blind people can read things by touching specific bumps with their fingers , right ? Now pretend instead of symbols like a stop sign , or writi... | AM and FM are types of radio waves that are used to transmit information, such as music, news, and other types of programming.
AM stands for "amplitude modulation," which means that the strength, or amplitude, of the radio wave is varied to transmit information. FM stands for "frequency modulation," which means that t... |
Why were dinosaurs so much larger than animals today ? Was it because there was a lot more oxygen in the atmosphere ? Please explain like I'm five. | One of the theories was due to the higher levels of carbon dioxide in the air . Plants in carbon rich environments grow very well but actually have less nutrients then if they grew in an environment similar to what we have today . So animals needed to eat a lot of plants just to get enough energy to survive . They deve... | Dinosaurs were not necessarily larger than animals today because there was more oxygen in the atmosphere. In fact, the concentration of oxygen in the Earth's atmosphere has varied over time, and it was actually lower during the time when dinosaurs lived than it is today. There are a few different factors that might hav... |
What if the Earth spun the opposite direction it does ? What it says on the title . Explain like I'm five. | do you mean the earth 's rotation ? or revolution ? If rotation , the sun would rise from west to east , instead of east to west . Besides that , I do n't think much would change . | If the Earth spun in the opposite direction that it does, the direction in which the sun appears to rise and set would be reversed. This means that the sun would rise in the west and set in the east, and the length of the day would be shorter than it is now.
The Earth's spin, or rotation, also determines which side ... |
Does "Student Athlete" status vary from sport to sport in the NCAA | Ryan Donato is no longer eligible to play NCAA hockey. He has joined the Bruins. He's still a junior at Harvard (and still attending classes apparently) but he isn't allowed to play hockey for the Crimson anymore. This was something that he chose, to turn pro early and forfeit his remaining NCAA eligibility. | Yeah, "student-athlete" status in the NCAA can vary based on the sport. Different sports have different rules regarding scholarships, eligibility, and the number of practice hours. For example, some sports have more rigorous time commitments and scholarship opportunities than others. So, while all athletes are consider... |
Why were the planes in the video(see comment ) flying wobbly and why some of the runaways are n't flat ? [ drunk pilots or heavy winds ? ] ( URL_0 ) Explain like I'm five. | Severe crosswind . Imagine looking down a runway that runs true North , the wind would be blowing from either the east or west . Pilots have to angle their nose into the wind to compensate for the air movements . Since wind is not a constant speed ( ie gusts ) it tends to move the aircraft around quite a bit , leading ... | I'm sorry, but I am unable to view any video or URL that you provide. Can you please explain the situation to me in more detail, and I'll do my best to help answer your question? Without more information, I won't be able to accurately diagnose the issue you are describing. In general, however, there can be many differe... |
Cars Gasoline and electric , please . Edit : sorry , forgot to search before posting , but I did n't see anything on electric cars . Explain like I'm five. | Vroom , vroom . Toot , toot . They make you go . Seriously , you have to be a little more specific than * that * . | Sure! A gasoline car is a type of vehicle that runs on gasoline, which is a type of fuel made from oil. When you put gasoline in the car's gas tank and start the engine, the gasoline is burned to create heat and power the car. An electric car is a type of vehicle that runs on electricity, which is a type of energy that... |
How is 'I am.' a complete sentence while 'I'm.' is not? | Although technically 'I'm' is a contraction of 'I am', there are differences in usage. 'I'm' is less formal, and is is universally followed with more words which describe what you are, usually an adjective (eg, 'I'm tall'). For instance, if I you asked me if I was a reddit poster, I could say 'I am', but I couldn't say... | "I am." is a complete sentence because it has a subject ("I") and a verb ("am"), which together express a complete thought. On the other hand, "I'm." is a contraction for "I am," but it feels incomplete because it's usually used in a longer context. The period at the end makes it seem like a final statement, but it doe... |
How Exactly Does Electrocution Kill You? | The majority of the time the electricity messes with your heart as it passes through the body (your heart runs off of electric signals from the nervous system so all that extra electrical input can clearly cause complications, usually in the form of a stopped heart) causing it to stop pumping. Then from that point its ... | Electrocution can kill you by causing your heart to stop or by disrupting your body's electrical signals. When electricity passes through your body, it can interfere with the normal rhythm of your heart, leading to something called cardiac arrest. It can also cause severe burns or damage to your internal organs, depend... |
Who creates the, I assume mostly not real, computer programs we see characters using in films and are they actually functional? | I would guess it's just added post production via a cgi program. No reason to write a fake program when all you need is something to just look like a program sense nobody has to use it outside of a scripted scene | Most of the time, the computer programs you see in movies are created by special effects teams or prop designers. They often make them look flashy and cool to fit the story, but they're usually not functional in real life. Sometimes, they might use real software or code, but it’s heavily modified or simplified to look ... |
Why are there seat belt laws? | If you get into an accident and are paralyzed for life, how much will society have to contribute to your health, housing, food, rehabilitation for the rest of your life? Insurance won't pay for it all. | Seat belt laws are in place to keep people safe while driving. Wearing a seat belt significantly reduces the risk of injury or death in a car accident by preventing you from being thrown around or ejected from the vehicle. These laws help promote safer driving habits and lower healthcare costs from accidents. Plus, the... |
Why we use chip readers. | The magnetic stripes on the back of payment cards are easy to read and easy to program, making them extremely easy to clone. An attacker only needs about 2 seconds with your card to read the data off the mag stripe, which can then be programmed on to a card of theirs and they can make payments with your (cloned) card. ... | We use chip readers because they make transactions more secure. The chip in your card creates a unique code for each purchase, which helps prevent fraud and identity theft. Plus, they’re harder to clone compared to regular magnetic stripe cards, so it just adds an extra layer of safety when you’re buying stuff. |
Why is it that you cannot fix a flat tire if the hole is on the side? | The tread surface of a tire is much more rigid because that's the part of the tire designed to make contact with the road. The sidewall is much more flexible because it is designed to adapt to changes in tire pressure without bursting. Sealing the tread is easy because the patch will remain relatively still, but a patc... | You can't fix a flat tire with a hole on the side because sidewalls are under a lot of stress when you're driving. A patch might not hold due to the flexing, and it can lead to blowouts. Plus, sidewall damage can affect the tire's structural integrity, making it unsafe to drive on, so it's usually safer to replace the ... |
What neurological processes are involved when "brainwashing" people? | Brainwashing is not a scientifically accepted concept. It's an idea that was made up in the mid 20th century and that people found interesting, but is not supported by evidence. [source](_URL_0_) Instead, what is happening is ordinary training. People are learning what others believe, and what they are rewarded for, an... | Brainwashing often involves manipulating someone's beliefs and thoughts through psychological techniques. It can include methods like repetitive messaging, social isolation, and emotional manipulation, which can create confusion and dependency on the person or group doing the brainwashing. This affects brain areas link... |
How do knots in your back form? and how does digging into them with someone's elbow get rid of them? | Your muscles - especially fast-twitch muscles - get overexerted. They lose the ability to "turn off" and spasm. Additionally, lactic acid and proteins build up in the muscle fibers. A good deep tissue massage or proper stretching or physical therapy will stretch the tense muscle, helping it to turn off, while also incr... | Knots in your back, or muscle tension, usually form from stress, poor posture, or overuse of the muscles. When muscles get tight, they can create these hard lumps. When someone digs into them with their elbow, it helps to break up the tightness and increase blood flow, which can relieve pain and help the muscle relax. ... |
If weed is legal now, what happens to the people in jail that where incarcerated for possession of it? | As a general rule, they're treated the same: they broke the law. Sure, the law changed later on. But in 2005 (or whatever) the law was X and they committed a crime by breaking it. It's that straightforward: they were found guilty of a crime. There are a few rare exceptions. I forget the exact language and I'm on mobil... | When weed becomes legal, it often leads to discussions about those who were jailed for possession. In many places, some people can get their records expunged or have their sentences reduced, but it really depends on local laws. Some states have set up systems to release or pardon those serving time for offenses that ar... |
Are infant deaths in hot cars on the rise, or is it this summer's "shark attack" news? | It's getting a lot of airplay this summer, most likely in the wake of one such fatality that [prosecutors think was intentional](_URL_0_). | It feels like every summer we hear about tragic cases of kids left in hot cars, and it often gets more media attention during warmer months. While the numbers can fluctuate from year to year, these incidents tend to be a consistent problem rather than a sudden rise. It's definitely a reminder for everyone to stay vigil... |
Why are ATM machines limited to withdrawing denominations of $ 20 ? I 've always wondered why this is the case , and why the minimum you must withdraw is $ 20 . Please explain like I'm five. | Not all of them are like that , some will let you do $ 10s and I 've even heard of some that will do $ 5s . But the simple fact is - it 's easier for the bank . They do n't have to stock the ATM with anything but $ 20s and it makes the back end work easier too . | ATM machines are programmed to dispense cash in certain denominations, and the choice of which denominations to offer is typically made by the bank or financial institution that owns the ATM. Many banks choose to offer $20 denominations because they are a convenient and widely-used size.
There are a few reasons why $2... |
how can a tv remote sit around all day not wasting it’s batteries and immediately be picked up and used (without having to be turned on), while something like a game controller must be turned on first before use, and if you left it on all day it would drain the batteries even while not in use? | a tv remote is a usually one way communication and uses IR. the remote emits a signal when a button is pushed and the tv receives it. it's like using smoke signals. a game controller communicates through bluetooth which is active two way communication. just by keeping it on and idle, it'll consume power. and controlle... | Great question! TV remotes usually use a simple infrared technology that doesn’t require a constant power source; they only draw power when you press a button. On the other hand, game controllers often use Bluetooth and have more complex functions that keep them “on” to maintain a connection, which drains the battery e... |
Is the energy used to run your body stored in cell themselves like water is? And how is the process of burning fat used to power your body? | You know the meme that the "mitochondria is the powerhouse of the cell". Well basically, the mitochondria produce a chemical called ATP. It uses the byproducts of the chemical reactions that break down carbohydrates, fats and proteins to make it. ATP then leaves the mitochondria and goes into the cell. From there, th... | Great question! The energy your body uses isn't actually stored in the cells like water, but rather in the form of molecules called ATP (adenosine triphosphate). When you burn fat, your body breaks it down into smaller molecules that can be converted into ATP through a process called cellular respiration. This ATP then... |
Why do some places of business lock one side of their double doors? | The doors they use have two locks, one with a key and the other a much cheaper frame lock with pins at the top and bottom. You can't open the second kind without opening the first door with the key. But people in retail are lazy. They don't open the second lock even though it is required by the fire code. Also the loca... | They usually lock one side of double doors for security reasons. By doing this, they can control access and prevent unauthorized entry, especially in places like banks or stores. It also helps manage foot traffic, making it easier for customers to come in and out through the designated door. |
Why does coffee only taste bad at it's lukewarm state? But tastes amazing if it's at a more extreme temperature? | Good coffee tastes good hot, warm or cold. Shit coffee tastes ok when your taste buds don't work...ie extreme temperatures. | Coffee can taste weird at lukewarm temperatures because that's when a lot of its flavors can get muted or unbalanced. At high temperatures, the heat brings out the rich, bold flavors, while cooler coffee can sometimes lose that intensity or pick up undesirable notes. So, it's kinda like how some foods just hit differen... |
Why are some people faster than others ? Obviously if you compare a track runner with a couch potato that wo n't be hard to explain . But when comparing two people of equal physical fitness what makes one person faster than the other ? Please explain like I'm five. | It 's just genetics , same thing applies to most people in any subject being " better " than others , that and the environment they were raised in coupled with their desire to achieve . | There are many factors that can influence how fast a person can run. Some of these include:
1. Genetics: Some people are naturally more athletic than others and may have genes that give them an advantage in terms of speed and endurance.
2. Training: How much a person trains and the type of training they do can also a... |

In the United States, there are two main political parties: the Democrats and the Republicans. These parties have different ideas about how the country should be run and what policies should be put in place. For example, Democrats generally believe in more... |
What do tax filing companies do during the off season ? It seems like customers only use them a few months out of the year . Please explain like I'm five. | There 's still people filing extensions and late taxes . And corporations file taxes year - round . | During the "off season," or the time of year when people are not preparing to file their taxes, tax filing companies may do a variety of things. Some companies may take the opportunity to update their software, train their employees on new tax laws, or work on marketing and advertising to attract new customers. They ma... |
Why does flushing the toilet make the water in the shower hotter? | Toilets use cold water to refill their tanks. Flushing causes the tank to refill. Showers mix cold and hot water to get the temperature you want. Cold water is diverted to the toilet leaving only/mostly hot water. More modern plumbing systems don’t have this issue, but its prevalent in older houses. | When you flush the toilet, it uses up some of the cold water from the pipes. This can create a temporary drop in cold water pressure, which means that the hot water in the shower can come out stronger than the cold. So, when the cold water flow decreases, it makes the hot water feel hotter since there's less cold to mi... |
Why does time move at the speed it does? | How would you know the difference if it ran at any other speed? It would still be "normal" to you. | Time doesn’t really "move" at a speed like a car or a train. Instead, it's more about how we perceive the passing of time based on events and changes around us. Scientists measure time using consistent intervals, like seconds, based on the vibrations of atoms or the movement of celestial bodies. So, the way we experien... |
what "your second cousin once removed" etc..means? | "Removed" refers to generations. For example, if one of your parents has a second cousin, that person is your second cousin *once removed*, because you're one generation away from being their second cousin. If one of your *parent's parents* has a cousin, that's your first cousin twice removed, because you're two genera... | So, "your second cousin once removed" basically means there's a generation gap between you and your second cousin. Your second cousin is the child of your parent's second cousin. When someone is "once removed," it means they’re either one generation above or below you. So, if your second cousin has a kid, that kid woul... |
how is boiling a live crab not considered animal cruelty? | I could be wrong but I believe they die in a matter of seconds. Also nobody really cares either way (most people) because they are delicious and it never crosses anyone's minds. | That's a good question! Boiling crabs is often seen as a traditional cooking method, but it raises ethical concerns for many people. Some argue that crabs don't have the same capacity for suffering as more commonly recognized pets or mammals, while others believe any method of killing animals for food can be cruel. The... |
How come people might stutter when they talk, but you don't stutter when you sing a song? | Music therapist here. It's the same reason why people with traumatic brain injuries who loose all ability to speak can sometimes still sing. The speech center of the brain is located in a very small part of the left hemisphere. When we are speaking, that part of the brain lights up. But music is associated with many p... | That's a great question! When we talk, our brain has to plan and control speech on the fly, which can lead to stuttering, especially if we're nervous or rushed. But when we sing, we often follow a melody and rhythm that helps us express words more smoothly, plus our brain processes music differently, making it easier t... |
How does time progress when there are an infinite number of points between units of time ? Why does it not just become infinitely closer to the next second ? Please explain like I'm five. | What you are describing is a version of Zeno 's paradox . From Wiki : " Zeno states that for motion to occur , an object must change the position which it occupies . He gives an example of an arrow in flight . He states that in any one instant of time , the arrow is neither moving to where it is , nor to where it is no... | That's a great question! It's actually a little bit tricky to explain, so bear with me. When we measure time, we usually use units like seconds, minutes, and hours. These units are just ways of measuring how much time has passed, kind of like how we use inches or centimeters to measure length. But just like we can't ha... |
Why is microwaved food bad for you ? My parents always tell me that microwaving food is bad , but they do n't know why . I 've heard some myths about the change in the molecular structure , but do n't quite get it . Explain like I'm five. | It is n't bad . Microwave cooking is n't voodoo magic . It 's just a particular way of transferring heat into food . There are three ways to get food hot . There 's conduction , convection and radiation . When you heat up a pan , then plop a steak down in it , the surface of the steak that touches the pan gets really h... | Microwaved food is not necessarily bad for you. In fact, microwaves can be a convenient and safe way to cook or heat up a variety of foods. However, there are a few potential downsides to using microwaves to cook or heat up food that you should be aware of. First, microwaves can cause some nutrients in food to break do... |
Reddit points, or why there are no posts with like 200,000, 500,000, or more upvotes | [Because of the 1% rule](_URL_0_) Simply put, only 1% of the community creates content, 9% modifies or edits, and the rest just lurk (hence the term "Reddit Lurkers"). This is compounded by 1. You don't need to upvote to view content 2. You need to take an extra step to upvote (creating an account/logging in) 3. People... | Reddit points, or karma, are mostly based on how many users interact with a post, and the site has a pretty diverse user base. The more upvotes a post gets, the harder it is to keep racking them up because the audience becomes more selective. Plus, there are only so many people on the platform at any given time, so it’... |
Why are there so many untested rape kits ? I understand that there are over 400,000 untested kits . Why ? Please explain like I'm five. | DNA testing is expensive and time consuming and police agencies do not give priority to old cases so many kits taken before DNA testing was widely available remain untested . | There are many reasons why there may be a backlog of untested rape kits. One reason is that there may not be enough resources, such as funding or personnel, to test all of the kits in a timely manner. Another reason is that some kits may not be prioritized for testing due to the perceived strength of the case or other ... |
What Does Data Actually Cost the Mobile Operators ? Not what they charge the customers obviously but what does the data cost the operators . I assume the figure will cost what they paid for the bandwidth from the authorities and the costs of network hardware / improvement etc Please explain like I'm five. | Your phone company is paying for bandwidth not data . It 's not about how much they download , it 's how much can they download at ONCE . 1 gb a second , 500mbit , 5 gb etc . But what about things other than the cost of data ? Someone has to pay to put those mobile towers everywhere . Someone has to pay to replace thos... | Data costs for mobile operators typically include the cost of the bandwidth that they purchase from authorities, as well as the costs of maintaining and improving their network infrastructure, such as purchasing and maintaining cell towers and other hardware.

Why shouldn't I drink water in Mexico? | Mexico doesn't have the same quality control on water that most other countries have. Because of this, their water often has little "bugs" living in it that will upset your stomach. When you drink water or eat foods containing these "bugs" your body cannot process them right because your body isn't used to them. Your b... | You might want to avoid drinking tap water in Mexico because it can contain bacteria, parasites, or chemicals that your stomach isn't used to, leading to stomach issues or "Montezuma's Revenge." It's generally safer to stick with bottled water or drinks made with purified water. Just be cautious about ice and avoid usi... |
Why some applications in Google Play have a high rating ( > 4.0), despite being either a horrible app in general, a scam, or clickbait? | Averages are easy to manipulate, especially given who tends to leave ratings. If my company makes a clickbait app; and has 20 people working for it, it's going to take 5 0-star revies to lower the rating to 4 (because we all voted it up). If each of us makes 5 accounts to upvote our app; it will take 25 0-star reviews.... | A lot of times, apps can have high ratings because of a few reasons. Developers might encourage users to leave positive reviews, sometimes even offering incentives. Some apps also have a big initial push with lots of downloads before any issues are reported, so those early reviews boost their ratings. Plus, some people... |
Why do we have 2 different kinds of screwdrivers ? I 've always wondered why there are 2 different kinds of screwdrivers . Is n't the phillips head more efficient because of more contact area ? EDIT : Thank you guys for satisfying my curiosity ! Please explain like I'm five. | Phillips head was actually designed to cam out ( the groves basically tear apart and the screw stops turning ) if the screw stopped driving into the material . Sometimes it 's better to have a damaged screw than damage to the rest of the object from over - tightening or damaging the screw driver or whatever . A slot he... | Sure! Screwdrivers are tools that we use to turn screws, which are special types of bolts that have a spiral groove on them. There are two main types of screwdrivers: Phillips head and flat head. The Phillips head screwdriver has a cross-shaped tip that fits into a screw with a cross-shaped indentation. The indentation... |
Why do planes at major airports sometimes take off in the opposite direction than they usually do? | They take off into the wind. If the wind shifts, they take off the other direction. | Planes at major airports might take off in the opposite direction due to changing wind conditions. Pilots prefer to take off into the wind for better lift and control. If the wind shifts or there are other factors like noise restrictions or weather, air traffic control will adjust the takeoff direction to keep things s... |

Like what is happening in the cloud that's different than before, or vice versa if it starts pouring like there's no tomorrow then slows down? | The cloud moves. First, the cloud's (thinner) edge comes over you, and because it's thinner there's less rain to unload; then the bulk of the cloud, then finally the trailing edge.

How can American Airlines file for bankruptcy but continue to buy brand new planes? | They're in Chapter 11 bankruptcy. In a Chapter 11, a business continues to operate as usual, it just goes through a judicial proceeding to create a "plan" to restructure its debt.
