Why do some things have 3 states of matter while others don't? | > Dry ice is frozen, but goes immediately into its CO2 state, skipping the liquid phase. It sublimates , at normal atmospheric pressures. But under higher pressures, it can also be a liquid. > Glass melts into a liquid, but does it ever become a gas? Glass isn't a single type of molecule. It's a mixture of different ty... |
A day in the life of a congressman | [This model daily schedule from a training for freshman Dems] suggests 4h a day calling donors, 1-2h meeting with constituents, 2h in official public sessions, 1h of "strategic outreach" , and 1h of "recharge time". The amount allotted for call time is low.While the chart that is currently the top link gives you a dece... |
the difference between a national park and a national forest in the US. | National forests are land that's owned by the government for the people's use in various ways. With the appropriate permits, you can hunt, cut trees, pan for gold, camp, graze pigs, etc. In national parks, the park *is* the use the land is put to. They're places come come and look at and spend time in, and the rules ar... |
How do game shows (like deal or no deal) make up for the large amounts of prize money they give away? | Gameshows are either big commercials , or their sponsors pay the prizes. Jeopardy, for example, has 1 on-air talent getting a salary, and 3 on-air talents where 2 are basically doing it for free, and one gets paid maybe 10k-20k? Ignoring production crew, which every show has, that's an awfully cheap way to generate 30 ... |
Why hasn't Apple made a physical television yet? | Apple enter markets where their skills can make an obvious difference or they can market a premium offering. television sets are commodities that are nothing more than huge monitors. there's not a lot apple can do in that area that wil make people buy new tv's. a small box that changes what is displayed ? that's differ... |
Why do cameras need to focus? Why isn't everything equally crisp? | Because they still need to converge the light onto the sensor . It doesn't matter how many lenses there are, you always have to get the light to converge to get a clear image and that will happen at different settings depending on the distance of the object being photographed. |
Why do people get pumped up from others cheering? | I'll take the down vote, but I 've read a lot about this. People emulate others around them. The temperament and emotions of a group of people transmit easily because of an individual's need to fit in. If you take a very confident person and throw them in a mob, the confident person, who does not rely on the emotions o... |
How they are able to say stuff like virtual reality will feel 100% real by the year this and that? | Very easily. You just said it yourself. There's a lot of bullshit in these sort of estimates. Any thorough explanation of how they get a date involves words like 'assuming' and 'extrapolating' a whole lot, but the real world isn't bound to respect such things. It's a vague guess, really. |
What makes something feel sticky? I understand adhesives like tape but why does, say orange juice, feel sticky if left on the hands or a surface? | Sugar and Salt are both crystalline in solid form, but when you add a bit of water they act quite different. One becoming sticky and the other not. This is due to oxygen-hydrogen bonds in sugar, when in the presence of a liquid, that start to break. This causes the loose hydrogen atoms to start to look to something els... |
Why can't twitter block ISIS accounts? | They do. They just create a lot of accounts and due to their methods it's hard to control them. I suppose that when you see an username on the news about a recruiting account on a social media it must be already blocked. If not they would give what every terrorist organization wants Attention", 'How would then do that?... |
How can the Hubble Space Telescope keep its lens pointed in the same spot to take long exposure shots when it's orbiting the Earth every 97 minutes? | Hubble uses six gyroscopes to know exactly where it's pointing. These are devices that act a bit like a compass, and always point in the same direction even when the telescope is orbiting. Next it has four reaction wheels which actually move the telescope. These just use Newton's 3rd law of motion; if the wheel spins o... |
why isn't 36°C the perfect external temperature for humans? | Our bodies generate a *lot* of heat, and dissipate that heat into the environment in order to maintain around 37 degrees internally. If the outside heat is near 37 degrees, we have great difficulty shedding that excess heat, which makes us overheat. |
Why do different instruments playing the same note sound different? | This is a frequently asked question. The Middle C in your example is just the "fundamental" tone, but notes from different instruments have more "overtones" or "harmonics" in different ratios, which define the tone. They can vary over time e.g. as a guitar string fades out, some overtones last longer than othersYes, th... |
Why doesn't YouTube make their app playable on the background? | Their app can play in the background, but it is a paid subscription service. They likely don't make it free because they think they will make more from the subscriptions than from advertising with "sound clips" rather than video advertising.Can they make it happen? Of course. Will they make it happen? Most probably no.... |
If a pipeline explodes where does the explosion stop? | It needs oxygen to burn, so the pipe itself didn't really explode. It leaked all over the ground from a ruptured pipe and then later caught fire and exploded. |
secret codes. Why is it so hard to make an unbreakable code? What elements contribute to the ease or difficulty of breaking a code? | Generally the fundamental principle of modern encryption schemes is that there are certain math problems, like factorization of primes, where it is really, really, super hard given some enormous number to FIGURE OUT the answer. However, if someone hands you the answer it is really very easy to VERIFY the answer. That s... |
When you're watching a live TV show that's on a set, how do all the cameras determine which camera is shown on the TV from your living room? | To build on /u/rhomboidus' comment The control room has multiple TVs, each displaying one of the camera feeds. This way the director can see exactly what each and every camera sees. There's essentially a switch board, and the director directs the crew which camera should be streaming into the live feed. He or she will ... |
Sometimes when I'm driving and I squint, the traffic and car lights turn into rays, why? | My best guess would be that its due to your eyelids causing the liquid on the surface of your eye to form a kind of [meniscus shape] over where light is entering your pupil. This would kind of be like a concave lens, leading to the bending of light in a vertical direction around where your eyelids touch your eye. edit:... |
How do coffee drinks suspend that much sugar in solution? | I bet there's a good chance they sweeten those drinks with some kind of high fructose corn syrup, which would probably dissolve in water more than granulated sugar.Syrup! The syrup is made my creating a solution where you mix a lot of sugar with a very hot liquid and more sugar than normal dissolves. Then you add that ... |
How come we automatically duck or lower our heads when we hear a loud sound, like a crash or bang? | I think the simplest explanation is that it's an involuntary reflex left over by evolution. Individuals with that reflex might have been more successful at survival. Startle reflexes are pretty much universal among animals. Normally, if something around you is an immediate threat to you and is accompanied by a sound, y... |
Why do Russian Nazi hooligans wave the swastika flag if it represents their worst enemy? | Whats the most "anti everything" thing you can wave in Russia? BingoBecause lots of young people in Russia and the old Soviet countries admire Hitler and Nazism, and consider the WWII to be the reason why the Soviet Union grew to become a superpower. Also years of Cold War has ingrained a siege mentality among the Russ... |
Why are some people so against protests? | It rarely leads to change - and it always leads to mass inconvenience for anyone in the vicinity. Bear in mind that the majority of people who are impacted by protests are the high and mighty, but ordinary people going about their lives who don't particularly care about the protester's issue one way or another. Think o... |
. Why is it called the birds and the bees??? | Bees pollinate flowers, which become fruits with seeds. Birds eat the fruits with seeds and then poop out the seeds elsewhere so the seed can become a new plant. Also they lay eggs which could be compared to a period. Birds and bees have integral roles of reproduction for many plants. *edit: periods*I believe that peop... |
How does a fish survive a thunderstorm? | Water can conduct electricity. Water does not conduct electricity well. If it did, we would run the electricity to your house through the water pipes and not need to run all those power lines. Because of this, the fish don't all die in a thunderstorm when a strike hits a lake. Only those that are close enough to the st... |
How does an atheist promise under oath? | You can choose to "solemnly affirm" rather than swear on anythingDont know about the US, but in the UK you get to choose what oath to give. Christians can say one on the bible, Muslims on the Quaran, etc. Athiests are given the chance to read an oath which doesnt mention God but says that they will be honest and true. ... |
Scott Walker's Seemingly Scandalous Policies | An important point is that he is weakening public unions, not private unions. I'll do my best to give the reasoning for this in an unbiased manner. Note that these are not *MY* arguments, just arguments I have heard expressed. It goes something like this: In the private sector, unions have a symbiotic relationship with... |
How does hypnotism work? Are all people susceptible? | In psychology, we 've figured out that hypnotism isn't really a thing. Any effect attributed to hypnotism is almost entirely due to to the "hypnotized" person being willing to trick themselves into believing it is working, so they just go along with whatever the hypnotist is suggesting. It's a placebo effect. |
Why is it that a lot of what we hear on the radio is censored while television seems to have more flexibility in which words are allowed/not allowed? | Radio is a public broadcast, and is [therefore subject to a federal ban on "obscene, indecent, or profane" broadcasts.] Cable, satellite, or internet TV isn't public and therefore isn't subject to the ban. Broadcast television is. |
What is that feeling you get when you feel someone watching you? And why does it happen? | It is called "confirmation bias" and it happens because all the times you feel that way and then look and nobody is behind you, you don't put them to memory. Then when it does happen to line up with someone being behind you, you remember that and feel like your gut feeling was right. |
Does light exist in 3 Dimensions or 4? | Everything in our universe exists in 3 spatial dimensions plus 1 time dimension, for a total of 4Imagine spacetime as a 2D axis with x,y,z on the x axis and t on the y axis. Everything travels at a constant speed c in this graph. When you are stood still you travel at a speed of 0 in x,y,z and a speed of c in t. You ar... |
1080i; 1080p. What do the letters mean? | The i and p stand for interlaced and progressive. Progressive is better and has better image quality and is what gets labeled as "true HD" or "full HD". Interlaced shows you first one half then the second half of the picture. It only shows every other horizontal line in each picture. |
Why does every charging cable for laptops has this little box where you connect the two cables? What is it good for? | That's the AC adaptor. Laptops run on DC power, like batteries. The outlet in your home provides AC power. AC must be converted to DC before your laptop can use it. Those old "wall warts" that video game systems and other electronics like electric razors and the like do the same thing.It's the transformer. It converts ... |
why are there two ways to write the number four? | The original 4 was actually "+". It dates back to the days of writing numbers as tick marks: a + has four sections but can be written in only two strokes of a pen, saving time and paper over "||||". All the modern forms of 4 are just stylistic variations on a +. The open-top 4 is relatively recent - it comes from the [... |
Why does my cell phone battery drain faster in a large city than at home in my small town? | In a small town there is generally only 1 or 2 cell towers that your phone is constantly connected to. When you are in a city there are many towers all over the place that your phone is constantly switching between causing your phone to work more and drain the battery faster', "it's scanning and establishing links with... |
How much of professional poker is based on luck, if everyone plays "perfectly?" | Poker isn't about having or playing perfect hands. It is about making others think you can beat them without saying anything.First of all, statistically speaking, amateurs are fairly represented in final tables. Its a common myth to think the same guys are always on top. Poker can be 100% about luck. If both players ju... |
What is actually happening (inside) when you plug a portable charger into itself? | It's not technically bad, it's just dumb . All that will happen is the charger will generate heat from the current while slowly losing charge to the resistance of the cable used to plug it into itself. Longer cables will provide more resistance, though most cables for such a thing won't be terribly long.; but ultimatel... |
Why does freezing food not destroy bacteria in the same way cooking food does? | There are lots of places on Earth where the ambient temperature drops below freezing for long periods. Because of that, many bacteria strains evolved have the ability to survive fairly prolonged freezes and revive unharmed later. There are far fewer places where the temperature gets above 160F, so most strains have nev... |
Why does time seem to go by much quicker as an adult than as a child? | Your brain remembers novel experiences better than experiences you've had before. As an adult, you've already experienced most things, so you don't pay as much attention to them, so time seems to go by quicker. |
Why don't GIFs wait until they are fully loaded to play? | GIFs don't wait around because browser's might not know when they end - it makes sense to continue the loop even if the download stops half way through. Why do GIFs take so long? They are far more inefficient as a file format than formats designed for video. |
Since almost all of the water on earth is saltwater, why didn't we evolve to be able to drink it? | There was always enough fresh water around that we didn't have to. Things don't evolve because it would be a good idea, they evolve because if they don't they die. Not being able to drink seawater didn't kill enough of our ancestors.Because historically humans lived inlandBecause we get most of our water through food s... |
Why is steel colder than plastic when touched in freezing temperatures? | We don't feel temperature. We feel the rate of heat transfer. Metal is a good conductor of heat, and thus "sucks heat away" from our hands faster than plastic at the same temperature. Thus is feels colder.There's a brilliant Veritasium video on [this topic] that explains that the reason some surfaces seem colder than o... |
Why is it that with how advanced we've become technologically, we still cannot have peoples medical records be able to be transferred between all the doctors? | It's entirely possible, depends on your country's healthcare system. Where I live we have exactly that. But in some countries there isn't such a system in place or healthcare companies don't share data to stop people moving to another company.- Who would be responsible? - How do you secure it? - How do you prevent misu... |
Why are graphing calculators so expensive, even with their archaic features? | Probably due to simple supply and demand - most high school math classes require one, as well as college level math, and TI has a huge foothold in Graphing Calculators. Also they are built very well with good materials and rarely break even when dropped.They haven't become more powerful in part because Schools already ... |
explain light years to me, 40 light years away is how far? | Current spacecraft can travel 17,500mph, the light travels 671 000 000mph. This means that it wouldn't take us 40 years to reach the planet, it would take us 1 533 714.2857 years. Longer than homo sapiens have existed. Let that sink in. To get there, the humans we send would have descendents that evolve on such a scale... |
What is the difference between a nightmare and a night terror? | Night terrors involve more than just a bad dream. They also involve thrashing, screaming, sweating, etc. etc., and they go on for extended periods of time. Extremely intense, violent terror with physical lashing out in other words. Night terrors are also almost never remembered by the victim, while nightmares obviously... |
why are republicans against states legalizing recreational marijuana? | In a lot of Republican controlled states, incarcerating non-violent drug offenders is very profitable. The private prison industry and the corrections industry are large contributors to GOP campaigns. State's rights are only for issues that don't mess with your financial contributor base. |
with a soda stream and syrup, why does it bubble over if the bottle is level, but doesn’t if you tip the bottle when adding the syrup? | It probably has to do with a greater surface area of liquid when tipped. Thus allowing more gas to escape the liquid. When sitting straight up the surface area is as small as the width of the bottle. When tipped it increases due to the angle. Take a bottle of liquid and view it yourself. |
How are illusions like this actually done? | He's using various slight of hand techniques to palm the birds into his hands, then he reveals them in a way that makes them look like they came out of nowhere. While it doesn't explain the exact clip that you linked, [check out this Penn and Teller routine], where they break down the principles of slight of hand. You ... |
Is there a good reason that funding for public schools in the United States is based on real-estate value, or is it just unambiguous racism? | It varies state to state, but a lot of schools are primarily funded at the local level, and the major tax base for local governments are property taxes.Public schooling, because it involves education and childcare, is one of the most personal functions the government serves. It's also very expensive; beyond just the la... |
why did gasoline have lead in it? | It's about the octane number of gasoline. In a gasoline engine, the air-fuel mixture is compressed by the cylinder, then ignited by the spark plug. If the octane number of the gasoline is too low, the mixture might already ignite from the compression alone. This throws the engine's timing off, and it might even damage ... |
How slugs and snails move | Essentially, they lubricate the surface beneath them and pull themselves forward by making waves with their foot. Put your hand flat on your desk. Now pull your fingers into your palm. Then push out from your knuckles so your palm is flat again. Sort of like that. Hope it helps. _URL_0_ |

Imran Khan is pissed by this and requested that NS give a temporary resignation to which NS refused. Add the firing on protesters by cops with tear gas, rubber bullets, beatings with canes, live ammunition, w... |
What gives gravity its energy? | Ok, i take it as you are wondering how gravity isn't breaking the laws of the conservation of energy. We cannot create or destroy energy, but we can transform it. So that means that gravity has to get its energy from somewhere, right? If you drop a brick from a building, then earth's gravity will pull it towards the gr... |
why do our noses run when we eat spicy food? | That's part of the inflammation response. The sinus and nasal tissues swell up, and mucus is produced in an effort to flush out the irritant. |
What does Bernie Sanders' "Too big to fail" bill mean when it says it is going to 'break up' big banks? | A lot of the biggest banks in the US are financial conglomerates that house many different kinds of businesses that touch many different areas of finance. They might have a division that does personal banking , a division that does commercial/corporate banking , and a division that does investment banking . The idea of... |
What is it about John Williams' music that makes me instantly recognize something he has composed without ever hearing it before? | I'm no expert, but I would guess it's the specific instruments he uses and familiar sequences that he uses in his music . Because of this, even though his music might be different in every time, it still has a familiarity to it and can be identified as coming from him. |
The different colours of flames and what each one can do chemically and physically if you come in contact with each of them | All fire is just light coming from excited plasma molecules. Different color fire is at different wavelengths, energy, and temperature. It may be the result of burning off different things in the plasma or other controls. Fire is fire and there's nothing particularly special about the different kinds. The different col... |
How come when were not thinking of something, we don't sense it? | And now you've made everybody self-conscious of their breathing! :-) I don't know the exact mechanisms for things like breathing and blinking, but I *imagine* it's a similar concept to when you place your hand on a table and you feel the surface, but after a while you forget about it. In these cases, it's to do with 'b... |
why plants leaves are green and not another more absorbent amalgamation of colors(generally) | There are different type of factors that determine what color plant leaves are. There is chlorophyll, carotenoids, anthocyanins, and tannins that pretty much determine the color. The fact that leaves are mostly green is because the chlorophyll is the more predominant substance and masks the others. Although in the fall... |
Why hasn't Algae Fuel caught on yet? | Interesting bit from the wiki: > The\xa0United States Department of Energy\xa0estimates that if algae fuel replaced all the petroleum fuel in the United States, it would require 15,000 square miles , which is only 0.42% of the U.S. map, or about half of the land area of\xa0Maine. This is less than\xa01⁄7\xa0the area of... |
How can f1 cars get 600hp out of a 1.6L engine; and normal, everyday cars get in the 100-200hp range? | They cost like half a million dollars and are made of strong, light metals that allow for more pressure to be created within the block, more PSI translates to a higher output. Plus, they don't have to meet US emission standards, which are absurd, so there aren't pieces 'cleaning' the exhaust and making them quieter.You... |
Why did the West used to classify Asian stereotypes as "yellow"? | Although color is a rather subjective matter, the normal range of skin tones historically found in East Asia can reasonably be said to include yellow-ish. But the idea that "Asian people" are yellow is a little arbitrary, the way that Africans are called "black" and not brown. It's worth noting "Asian" in the United St... |
If Linux is free and easy to install and use, why isn't it more widely used? | Look, I love Linux as much as anyone else, and it's how I make my living. But Linux is not as easy to use as either Windows or MacOS for casual, everyday users. There have been great strides at closing the gap, but there's still a learning curve involved. Also, many people won't have an interest in it because many of t... |
Why do some older films (think 70's) have the majority of their credits at the beginning of the film? | When I remember the story correctly, that was the norm back in the beginning of the film-industries. Filming was an art that was meant to be acknwledged, and since people normally do not watch the end-credits , it was natural to put it first. This changed with George Lucas and Star Wars who reversed it, showing the cre... |
Why is 0 divided by 0 undefined when any other number divided by its self equal to 1? | 0/0 is not undefined. It is indeterminate. _URL_0_ Imagine you have 5 rasins and you divide them into piles of 5. How many piles are there? If you said 1 you are correct because 5/5 = 1. Now take 0 rasins and divide them into piles of 0. How many piles are there? Well, you might say there are 0 piles and you would be r... |
why do republicans routinely refer to the "democrat" party, "democrat" nominee etc. instead of the word democratic? | Because to their target audience, the word "democratic" is a neutral / slightly positive word , but the word Democrat is a bad word . So yeah, just pettiness.Well, both parties are democratic. That describes the entire American political system. They're referring specifically to the members of the Democrat party. |
why does Hudson's Bay have such a round cut out of it on one side | When you take a bow and draw back the string, it bends in an arc. The general theory is that the land itself bent in a big arc during an ancient period of mountain building, and the remnant is the Hudson Bay arc. The Hudson Bay is located in a very stable part of North America that hasn't really done much of anything f... |
Why does a sunrise light up the sky differently than a sunset? | During the day, you've got a number of things happening. The sun is beaming down and evaporating water from various sources, lakes, rivers, oceans and rain. When you combine the haze from this with the everyday increase in traffic and industry pollution, you get a ton of particles in the air that weren't there in the m... |
How can my headphones have control over my iPod? | It's not just a regular 1/8" plug, which is a TRS . It's a TRRS plug, ie tip-ring-ring-sleeve, giving you an extra signal line. You can send an asynchronous serial signal over a single wire. I'm not sure the iPhone/iPods necessarily do this, but it seems likely.The headphone jack can also [read credit cards]. To answer... |
What's happening to my body when I get butterflies in my stomach? | Because you're nervous, your body anticipates a threat, and when adrenaline is released into your blood it affects different parts in different ways: - blood is directed towards your legs and other muscles - blood is directed away from your stomach . Hope this helps!", 'Cortisol is being secreted and stress is literall... |
Why do rainbows seem to have individual bands of color as opposed to a gradual color shift? | They don't have individual bands of color, and do have a gradual color shift. You tend to interpret the gradual shift as individual color bands, but that is largely your brain that is doing that. You may be thinking of illustrations of a rainbow, where artists draw bands of color - but that is not what rainbows are lik... |
Is scar tissue just the bodies lack of ability to generate large amounts of healthy normal tissue at the necessary rate, or does it actually serve a purpose? | Scar tissues are made of the same materials as the tissues they're healing, with the exception of structure. This is because the tissue they're trying to heal has been damaged - the "blueprint" for how to generate the original tissue structure is lost. So, instead of having a uniform fiber structure to the tissue that'... |
How do the leading cars somehow get back in the same lead formation after a pit road stop in NASCAR? | Usually when the lead cars pit the majority of the field will pit because eventually cars that stay out will have to pit. So if you dont pit when they do, you stay out with less fuel, tires etc. So now when you pit, all the cars the previoisly pitted will be passing you. A lot of cars if down laps will stay out to get ... |
Why do objects turn black/brown when they're burnt? | The black is basically elemental carbon. Most organic material like wood is made up of compounds of carbon, hydrogen and oxygen. These combine with the oxygen in the air, producing carbon dioxide and water. Excess carbon gets left behind as sootFrom the NakedScientist: " it does depend how effectively you burn them. Mo... |
Could a very steamy shower and closed door cause a person to asphyxiate from too much steam and too little oxygen (being pushed aside by the steam)? | Nope. Water vapor occupies space between gaseous molecules like carbon dioxide and oxogyen. You could have an area of 100%water vapor if it occupied a space that didn't have any other gasses in it before but if not the gasses would mix almost evenly.Quite simply, no. The human lung has evolved to operate successfully i... |
Why don't your kidneys process alcohol? | Because alcohol is metabolized by your liver before it reaches your kidneys So much less of it gets there. Unless you ass-bong some vodka. |
How does satellite internet work? | There's a satellite up in space and a dish on the roof of your house. When you try to go to a website, your computer sends a request through the dish up to the satellite. The satellite sends that request down to it's company's tech center and they fetch the website over the internet. Then that data gets sent up to the ... |
Why don't I have to enter my PIN for my debit card at McDonalds, but I do at other places? | They're running it as a credit card. It still works the same way. The company I work for does the same thing. |
How does body hair know what length to grow to? | hair doesn't go to a certain length and stop, it goes to a certain length and falls out. hair on your scalp lasts longer, and therefore can get longer |
How do key generators for popular programs, Photoshop, Sony Vegas, Adobe Premiere, etc. work? | A key for a program is created by some advanced math formula that allows you to create a set of values that, if you use another formula that is something like its twin, will say that, yes, the key came from the first formula. What a key gen does is use a formula that crackers have figured out by looking at the formula ... |
Why is it so difficult to fire state/federal employees? | Unions. Unions made it hard. The unions for government employees tend to have a rather large amount of power, and have made it difficult to fire them, even when there's plenty of justification for it. |
Where did the "many clowns in a tiny car"-gag originate? | I had to do a little research for this, but apparently it has always been a circus act. It originated from the "Cole Bros. Circus" in the 1950s. According to circus performers, the average car can fit between 14 and 20 clowns when all the interior is stripped out, there is no use of trapdoors or the like, and the cars ... |
Why is every major issue in the US called "The War on _____"? | Because it's easy to get people behind something if you call it a war.Well two of the things you listed are actual wars so those are obvious . Better examples: "the war on women" "the war on Christmas" A similar trope that annoys me is calling every scandal _-gate because of Watergate. |
How are toilet paper rolls sterilized? | TP rolls are not sterile. We do heat the paper to extreme temps while being made on the paper machine but they are sometimes not converted for a few days. Once it goes through the converting process it is cased and send to the warehouse. It can sometimes be there for a week before it’s sent to the store for purchase. Y... |
Why does food someone makes for you seem to always taste better than when you make it yourself? | Smell is an important part of the overall eating experience. A lot of what we believe to be taste is the smell of the food. That's why food tends to taste worse when your nose is stuffed up. So when you're cooking a meal, you've been exposed to the scent, and you get used to it. By the time you eat it, it's not excitin... |
Every K-Mart I've been to is outdated, old, and seems to not be flourishing as they probably once were. As a company, how are they still surviving? | By not spending money on inventory and repairs. Kmart also bought Sears which helped them out, but they're still closing stores left and right. It's just a matter of time. |
Why does Orange juice need to be constantly refrigerated but not Apple or other juices? | Shelf stable juices undergo pasteurization and are sealed inside the bottle. They must be refrigerated after opening because once more air is introduced the chance for molds to grow is higherShelf stable orange juice exists. It has been pasteurized and usually has potassium sorbate added to prevent mold and yeast from ... |
The Democratic Party used to be the party of the South, while the Republicans were the party of the North. When, and why, did it switch? | Well, this is a gradual process, and you basically have to realize that the "Solid South," the strong Democratic hold on Southern states was because of Democrats being a "big tent" party. The party policy had plenty for many of the blue collar workers in the Southern states, like an alliance with unions and support for... |
How do non-flush urinals work? | There is a sort of gel type thing in the 'canister' in the bottom. It is lighter than water/urine, so when you pee or clean the urinal, the stuff all sinks below this layer. If you were to open it up it would look a bit like oil on water. This keeps the smell from propagating. It 'flushes' because when you pee into it,... |
