How do websites like 10 minute mail generate infinite emails? | An e-mail address is made up of two parts: the local-part and the domain . The domain determines which server will handle the e-mail - for example when you send an e-mail to barbzyy at _URL_0_, your e-mail provider connects to a server at _URL_0_ and tells is "please deliver this e-mail to the user barbzyy". Creating n... |

Why we don't use 2d programming languages? eg.- > < > or gol > < > | Those languages are so called esoteric programming languages. That is they where never intended for practical use. For these languages in particular they are impractical because are pretty hard to write, even harder to read and nearly impossible to modify without introducing any bugs. And they don't really give you any... |
Why television shows only bleep the "hole" in asshole | "Ass" can be considered "[donkey]". "Asshole" leaves no room for interpretationAss can refer to a donkey or your butt in general.

Why it feels so much better when someone else scratches your itch. | Usually, it is because if you itch yourself, you are aware of the exact spot of the itch and you scratch there only. Whilst this is good, it also is abrasive/irritating for the skin and becomes painful after a few strokes. When someone else scratches you, the strokes are all over the place. Not being so focused helps t... |

Some people live longer than others because they are lucky and don't get diseases like cancer, arthritis, parkinsons, dementia, or Alzhei... |
Why is it that some meats like beef don't have to be fully cooked while other meats like chicken and pork aren't healthy unless cooked all the way through? | Beef isn't universally safe to eat undercooked. Ground beef should always be cooked to at least 155F. Steaks can be cooked to at least 130F because the most common beef contaminate only contaminates the surface of the meat. If you cook a contaminated steak, all the exterior bacteria will be killed even if the inside is... |
Considering almost all of our voices are different, how can voice recognition services like 'Talk-to-type' offer services for all tones and accents? | That's actually a very interesting Problem and the honest answer is that we don't really know how it works. Voice recognition is one of the typical applications of Machine Learning. That means you have to give an algorithm a voice command, let it do its thing and afterwards give it feedback. So basically like training ... |

why do we find it unacceptable to kill criminals of all nature in our country but it's perfectly fine to kill people during war? | It's all based around how personal it is and dehumanization. Our own criminals are still our own people. We want them to either be rehabilitated or we want to see them suffer in prison. In war, we dehumanize the other side. They aren't people, they are baby killing Nazis, they are repressed communists, they are evil te... |
Why does glue harden so quickly out of the bottle relative to inside? | Glue hardens when the water that's mixed with the polymers evaporates. It's much much harder for water to evaporate from inside of a bottle.it is subject to some air but very little, with minimal surface to contact that air. Most glues work by either evaporating a liquid carrier like water or some sort of solvent or it... |
Why do men go bald, while women do not? | Women can go bald, but it's usually not as extreme as in men, for reasons the other folks listed. In addition, when a woman begins to go bald, they generally do it evenly over their entire head, which is easier to camouflage, instead of the opposite "male pattern" baldness, where one area goes completely bald and anoth... |
Why did it take until after a major epidemic to come up with an Ebola vaccine. It's been around for far longer. Why did it come into existence so shortly after an outbreak? | On the off chance the bot is wrong and it hasn't been answered:Because making vaccines takes money, most countries in Africa don't have that kind of money, and the people that do in other countries don't care because Ebola doesn't affect them. It's callous, but true. There are definitely researchers who absolutely care... |
Why does nearly every forum/social website use emoticons, but it seems like an unspoken taboo to use them on reddit? :( | Different places have different cultures. I'm guessing it's just the upvote system. Emoticons look childish, so they get upvoted less.To me, emoticons are immature and distracting. Posting a comment that just has an emoticon with a pistol that shoots out a flag that says, "pwned" doesn't add anything to the discussion.... |
With all these posts of Edward Snowden applying for asylum, I'm curious, how does one wanted by a government apply for asylum? | Typically you go to country A, which grants you temporary entrance which your case for asylum is being heard. Sometimes it gets difficult. You might have to hang out in country C for a while, hoping they don't deport you to B, or sneak into A illegally and hide out until asylum is granted.Note to the NSA: /u/philhasred... |
Are you legally obligated to give the police your name, should you be stopped? | In the US, it varies greatly from state to state. In *Hiibel v. Sixth Judicial District Court of Nevada, 542 U.S. 177 *, the Supreme Court ruled that state laws requiring people to identify themselves do not violate the 4th Amendment. About half the states have enacted such a law, and the details vary greatly. Some sta... |
Why do we "lose our voice"? | Long answer short: Vocal chords are muscles that vibrate to create sound. Just like working out your biceps or legs, you strain the muscle. The same thing happens to your vocal chords. That's why your arms hurt after you do bicep curls, and why your voice hurts when you scream for a long time. |
Difference between quantum psychics and normal psychics and what is the point of quantum computers? | I've been asked this question more times than I like to count. Frankly, I don't have s good answer to you. And I've never heard anyone else have one. Quantum mechanics requires a fundamental shift in how you think about reality. I personally call it the intuition gap to students. Everything you know about reality tells... |
Why can I whistle in tune but cannot play/understand bars and chords on an instrument? | because you haven't practiced it. when whistling, you learn within the first few minutes that 'if I do this, this sound comes out'. when you're given an instrument, there's a *lot* more things you could do to produce different sounds. eventually you'd get the hang of it, but there's just a lot more possibilities, so th... |
Why do we look different in a mirror and in a photograph? | When you look in a mirror you're seeing yourself backwards. As in the sides of your face are flipped. When you look at a photograph the sides of your face aren't flipped. The reason it looks different is because the two sides of everyone's face have small differences. You don't notice them because you're used to seeing... |
What is the difference between disc and disk? | In medicine, it's disc for ophthalmologic terms , and disk for other parts of the body. In other areas there's no real consensus on which is which and people basically use whichever spelling they prefer like with gray and grey."Disk" refers to magnetic storage media, such as hard drives and floppy disks. "Disc" refers ... |
Why doesn't Comcast give customers the fastest speed that they possibly can. | Because business. First, it *does* cost them money to provide. Customers are wired together into cable segments. Each segment has a finite amount of bandwidth. If customers use twice as much bandwidth, segments can only have half as many customers, so they need to install more equipment and wiring. Second, it reduces t... |
Who, if anybody, will legally be at fault in the event of two driverless cars crashing into each other? | No one knows yet. One of the biggest obstacles to driverless cars is a legal framework that covers these kinds of situations. California and some other states have pass some laws that start to address this, but there is still a lot of things to figure outSo far, there has yet to be an accident where the car is at fault... |
- The "Brain Storm" / "Green Needle" Audio clip | Almost positive it has to do with your brain making up for the lack of real distinguishable sound. Similar to the blind spot in our eyes that our brain "interprets" what we should be seeing in that area based on our surroundings someone correct me if I'm wrong. |
Why can't camera phones always film in landscape mode no matter what direction they are being held? | Because the camera sensor is rectangular. You could have such a setting, but you'd have to lower the resolution of the final image.Using this as an illustration:_URL_0_ Black outline is the phone, blue outline is the sensor . The red outline is what would need to be used if filming horizontal video while phone was bein... |

Why is it socially taboo to "denounce, disagree with, or completely go against" Israel? | It's not taboo. But the Israel conflict is part of a quite impressive media propaganda war. All directly involved parties make insane profits on it. Arafat for example became a billionaire simply by embezzling development aid. Even got a peace nobel prize for it. Whatever, if you comment on this conflict, make sure you... |
How were the first metals mined? | Copper the first. You can find its ore in fairly pure forms and cold work it into stuff like bowls. Then they discovered that heating it made it softer and easier to work Then it was found that melting it and mixing it with tin resulted in Bronze which was much sturdier than copper or tin, and thus began the Bronze Age... |
Why can't sparkling wine not from the Champagne region be called champagne? | That has been the law in Europe for some time, and the law in America since 2006. Any American company that labeled their sparkling wine as Champagne prior to 2006 can continue to do so, but no new labels can use the word. Europe has a lot of such laws, called PDO . America has some also. Vidalia onions can only be lab... |
why does cooked fish *flake*, while things like chicken and beef *shred* | Look closely at a filet of fresh salmon, cod, or halibut, and you'll see pearly webbing between the striations of muscle. This is the connective tissue called collagen, a structural protein that holds together short, thick muscle fibers. In fish, muscle fibers are much shorter than they are in beef, and collagen dissol... |
Why is pride considered to be part of the 7 deadly sins? | Its important to know that the 7 mortal sins are not themselves sins. They are the 7 things that lead to sin. That is why murder is not one of the sins, nor is rape or theft. Wrath Lust and Greed on the other hand are the causes of sin along with others. So Pride is one of the 7 because it leads you to believe you are ... |
Are things expensive in Australia because of the high minimum wage? Or is there a high minimum wage because things are expensive? | Prices for most goods were traditionally very high due to Australia's isolation and low population -- it was expensive to ship stuff here and not a lot got shipped when it did. As that has become less and less of a problem, most prices remain high because people already established themselves as willing to pay that muc... |
VIDEOGAMES - Why is Final Fantasy 7 (seemingly) the most popular in the franchise?? | This is arguable, but a few points to consider * It was Square's first 3D Final Fantasy. Every FF prior to 7 was 2D, and used sprites. * It was widely marketed, where a lot of RPG's prior to that might have been lucky to have an ad in gaming magazines, FF7 had TV commercials. Not that it was like the first game ever to... |
When moving from Colorado to Washington state, what differences in laws should I expect? | Sounds like you're asking how weed law differs? I'm not certain. If you're going to be anywhere near the Oregon border, it's important to remember to do all your shopping in Oregon. No sales tax. you do have to pump your own gas however. Seattle has a city-wide ban on plastic bags, so if you're going there, make sure y... |
I understand why we have 2 ears and 2 eyes. Why do we have 2 nostrils? | _URL_0_ Most people only breathe through one nostril at a time, its called a nasal cycle. I don't know much about it I just remember reading an article or a TIL some time ago. Check out that article. |
How are pillars build into water? ( especially for old bridges on big rivers) | Depends on how deep they go. When they built the Brooklyn Bridge, for example, they built huge [cassions] so they could work on the river bottom to get the footings right. Other times they just build [cofferdams] around the base of the pillar. Generally you're going to have to get down there You can't just drop it from... |
If the Manhattan Project was able to create nukes in only 7 years, 70 years ago, how could it seem so difficult for Iran to create them? | There are basically two scenarios. The first is the argument to effective intelligence. Despite inspectors not being allowed into the country, Mossad has kept careful track of Iran's nuclear progress, and has assassinated most Iranian nuclear scientists. In this respect, inspections aren't necessary to prevent Iran get... |
how are lead aprons or suits flexible? | the lead inside isn't a solid plate of lead. it's lead pellets. and it bends just like a sandbag can be moved and twisted |
- Why do creams like Bengay or RubA535 make my skin feel hot, but not on the hand that rubs it in? | Your fingers have less nerve endings than other body parts. That's because they are used to grab pretty much anything. If they were too sensitive to touch, then more things would hurt, you'd touch fewer things and be less likely to do anything -- meaning our evolution would have been less likely. |
What are burns? And how does fire burn people? | Most of the fire we see is the result of something called oxidation, meaning that it is energy released by combining oxygen with something other chemical . So, when wood is burning the energy added to the wood allows the carbon in the molecules that make up the wood to break apart, combining with oxygen in the air, tur... |
Assume I am charging my phone, and the power went out in my city. If electrons flow from high to low, what is stopping the electron from flowing backwards? | Trying to be truly ELI5: The power coming out of the wall is 120V AC. AC stands for alternating current, which means that the flow of current for things plugged into the wall is going back and forth, positive and negative, very rapidly . Your phone's battery supplies DC current to the phone to operate, and is charged v... |
who pays for the 'debt' or so when a movie hasn't made anything close to their budget? | The money comes from the producers. Typically they'll borrow the 100M but sometimes they just put up their own cash.

Aspertame/sucralose vs sugar, how it breaks down, is it really any better for you, and what are the negative health consequences of them? | Sucralose doesn't break down so just passes through your system, but aspartame is broken down into three things: Aspartate, a common amino acid. Methanol . Phenylalanine, Another common amino acid . Aspartame thus does not produce fat as it is not a sugar. It is not considered toxic, despite the methanol production, be... |
How do pop ups on most streaming websites work ? The kind that pops when you click on the play button, and must repeatedly be closed ? | I'm not sure if you're looking for a technical answer or what. But those kinds of ads are built by computer programmers, who can make your computer do almost anything, given enough permissions to the machine. Usually, these ads function off of JavaScript and/or flash, which allow access to the browser. Also, clever pro... |
How does a car know to activate the anti-lock brakes when it is sliding? How do anti-lock brakes release the brake if the user is still pressing it? | Speed sensors detect rapid deceleration in tires to see if they're locking up. The ABS controller then opens/closes valves that control the brake lines to increase/decrease pressure on the brake so that the tire keeps accelerating . You'll feel it yourself on the brake pedal as a sort of "pulsing".The anti-locking syst... |
Why does trying to read a scratched CD/DVD pretty much freeze up your computer? | Some things on a computer are never expected to take much time, so it sends the command to do it then just sits and waits for the result. With a scratched CD/DVD the drive itself decides to try again over and over before giving up. The computer just sits there and waits. And waits. After a short timeout the drive gives... |
What's stopping another disaster like Chernobyl from occurring again but in much more highly populated areas? | irrc, the entire cause of Chernobyl disaster was a string of problems. Nuclear power plants have *a lot* of security protocol. Especially now. Chernobyl was caused after the staff wanted to test if the coolant systems would still function to keep the plant safe even in a situation where power is lost causing security s... |
why do Aquariums feed dugongs lettuce? Lettuce doesn’t grow underwater | The price of lettuce is substantially less than aquatic based plants. This makes it cheaper to use it. Also marine veterinarians have seen that it is healthy for the animals as well. Most veggie eating animals can eat lettuce and most greenery so where it grows doesn't matter. It is such a simple plant I don't think it... |
Why do we think about the universe from more of a horizontal standpoint and not a vertical standpoint? | That's how human brains are wired. To us, the world is horizontal, because that is how we interact with it. We travel miles horizontally, but mere feet vertically. |
Why does a pocket of puss form when you burn yourself? | It shouldn't be pus. Pus means there is an infection actively being fought. The clear fluid is called "serum". It's meant to puff the dead skin out to create a pillow/bubble. This then all works together to keep the raw, sensitive skin beneath from being damaged while the blister heals. |
What's stopping someone from taking the presidential office and ignoring lobbying efforts from campaign contributors for four year? (Assuming he/she doesn't get re-elected.) | The fact that you can't do much with out congressional approval and funding. Lobbyists aren't as big a problem with presidents per se, since like you said they only face one reelection. But president's are seriously restricted in the types of initiatives they can pursue if Congress is fighting them .Like you said, they... |
How exactly does Chromecast work? | The Chromecast plugs into your TV. From a Chromecast-enabled device , you can use the *Cast Screen* option to stream whatever is displayed on your device onto your TV screen.

Fiber Optic leading to high quality surround sound | Light is just an easy way to transmit data quickly. With digital encoding, you can easily encode multiple channels into a fast stream rather than going the old school method of having a cable for every channel. Then a digital to analog converter takes the digital information, converts it to analog so you can hear it an... |
Why animals can only hear within certain frequencies. | Our eardrums vibrate - but that's not how our brain senses sound. The eardrum only transfers the sound from the outer ear to the inner ear. Within the inner ear is the cochlea, the part that actually senses the sound. The cochlea is filled with a fluid, and the sound is transferred into this fluid. Along the inside edg... |
Why do subtitles sometimes include descriptors for sounds that are clearly inferred? | Some sounds may be vital to the scene or the progression of the plot. If a character is hiding in a basement from a murderer and we hear a creak that comes from off-camera, we know the murderer is coming. A deaf person might not realize that without the subtitlesIt just adds to the experience. You might also ask why th... |
the sun has a peak on instesity at wavelengths that correspond to the Green color, does it has any association with plants being Green? | A good explanation is given here _URL_0_ There isn't a consensus answer why plants are green. But some ideas are that by reflecting the green light it prevents the leaves from over heating, the leaves are already getting all the light they can use , chlorophyll is evolutionarily the best molecule, early bacterial life ... |
Why does the filming of Soap Opera shows always look a certain cheapish way? Can't they afford better cameras? | It's not so much the cameras as the lighting. Soaps are filmed quickly, using multiple cameras. In a movie, when you switch from one angle to another, the director will generally take the time to change the lighting to accommodate the new point of view. The director of a soap can't afford to slow down a production like... |
why cant we just send money to other countries to pay for their food? | I think in the future this will be a good idea, but right now it wont work for this reason: many of the populations of developing countries are still of the old-school mindset of having as many children as possible. And they dont have access to contraceptives, and have no concept of family planning. So no matter how mu... |
The All Writs Act of 1789 - How does it work in regard to modern technology such as encryption? | The All Writs Act has no relation to encryption, specifically. It simply gives broad authority to courts to issue orders that are required to effectively operate and apply the law. Recently, the government has used the act to request orders for people to decrypt data that is important to a case--sometimes parties in th... |
Why water isn't flammable? | Fire is what happens when oxygen rapidly combines with some other compound, releasing a lot of energy. Water is what's left when oxygen has finished combining with hydrogen. You could think of it as "hydrogen ash". There's no spare energy left in the molecules to release by combining into other stuff.Water is hydrogen ... |
Is making porn still big business with all the free porn nowadays? | Porn is still big business, though certainly not as big as it was. I managed a porn store for a few years about 4 years ago and before I worked there, I thought the same who is buying/renting these movies? As it turns out, lots of people. At least half our business was movies. I often asked our regulars, who I got to k... |
Why is weather radar still in 2D instead of 3D? | I am sure the real weather models use 3 D in the sense that they figure vertical data points through the atmosphere. So weather modeling is three dimensional. Weather radar still shows you a range around you of several hundred miles. Two dimensional displays work well and give you plenty of information. It is like aski... |
How do Jellyfish leave fossils? | The soft parts of animal bodies don't fossilize. But it is possible that after an animal dies, it could become covered with other material like ash or silt or mud before the soft tissue rots, and even after it's organic material has vanished, it's "shape" might be left as a distortion between the layers of material it ... |
Why do cheeseburgers cost more than hamburgers if the rest of the toppings (lettuce, tomato, pickle, onion etc) are free? | Mainly for profit. Yes, a slice of cheese has a cost associated with it, but it most certainly isn't $.50 or $.75. Look at a package of cheese slices at your grocer, a pack of 12 slices costs about $5, or $.42 a slice. Now go buy a bulk pack of 192 slices on Amazon and that same cheese can be purchased for $.33 per sli... |
Double Clutch Transmissions with a Torque Converter | The issue with most dual clutch transmissions is that the engagement of first gear when coming away from a stop can feel abrupt when you're just trying to slowly accelerate away from the light. Similarly, in gentle cruising situations, dual clutch units can have slightly jerky gearchanges. By adding a torque converter,... |
the location of things in outer space. | Stuff in the space tends to rotate. If some stuff didn't rotate fast enough, it would collapse into the center of the mass, because gravity pulls it there, rotating is the only way stuff can not-be at the local gravity center. See for example planes and satellites. Planes fall off the sky if they ever run out of fuel, ... |
How does Autism give some people incredible logical ability? Does it 'unlock' capability we all have, or provide additional capability? | We people with autism have a certain parts of our brain undeveloped, but other parts are developed greatly. Mainly the one that is undeveloped is the small brain so that we lack of social skills and body coordination . For the overdeveloped brain parts.. some people have a powerful logic, others might have their 5 sens... |
f humans are 95% similar to chimpanzees then why aren't there more chimp-human organ transplants? | Because organs have to be a lot more similar than that. Even among humans, you can usually only get organ donations from close relatives or strangers who happen to randomly match your cells' markers.Zoologist here I have worked the last 10yrs mainly in and around many chimpanzee environments, mainly checking population... |
How do competitive eaters fit all the food they eat in their stomach? | You eat massive amounts in training and it stretches out your stomach.

How do officers issue you a ticket when you are a pedestrian or cyclist? | They ask you to identify yourself. If you refuse, they arrest you, and if you lie, you've commuted a crime. So most people just tell them the truth. |
What is happening in my brain when I'm in a mood where everything makes me irrationally angry? | Look for physical causes: you could be hungry, tired, or suffering an allergic reaction without realizing that it *is* an allergic reaction. People think allergies are only about itchy eyes and sneezing, but they can cause sometimes extreme irritability, as well as severe depression, while never causing a single sneeze... |
How did prostitutes manage not to constantly get pregnant back when there were no condoms or contraceptive pills? | a lot of people think that there's a high chance of getting pregnant per every encounter that's not really true. If you only are "active" or so to speak in times other than someone's peak fertility, odds are they won't get pregnant. That does not mean you should have lots of unprotected sex. Wrap that shit, you don't w... |
According to the commercials, the US Mint makes thousands of silver and gold coins and never circulates them until the commercial gets them. Why? | The US Mint sells uncirculated coins, in rolls or bags, [on its web site]. Collectors of all kinds buy them. Some companies try to sell them through commercials, to folks who aren't big enough collectors to buy them by the bag. |
Why do helium balloons on a string deflate, but helium balloons on a stick never deflate? | Helium balloons on a string are normally latex balloons. The ones on the stick are usually made of Mylar. There is a different amount of insulation between the two materials and the outside of the balloon causing one to float longer than the other. From what I understand anyway.Aren't the ones on the stick just air, an... |
what would happen if I plugged my power bank into itself? | If the device is what I think it is , then plugging it into itself will create a rather low powered space heater. Ie, the bank charges itself, slowly wasting electricity due to some inefficient parts.If it's a cheap poorly designed and not UL/CSA/whatever certified device it could cause some problems But most likely wh... |
how does the material on the other side of a sticker keep the glue sticky? | It doesn’t. The glue does in fact dry out . However, if you’re referencing the waxy paper that the stickers originally come on, the wax paper allows the sticker to not be exposed to the surrounding air, therefor the water in the sticker’s glue doesn’t evaporate, the glue doesn’t dry out, and the sticker remains sticky.... |
there's not water on mars okay, but what would happen if say we took a bottle of water and poured it on mars? | It would probably freeze long before the ground could absorb it. Mars is always below freezing and the temperature can get as low as -133C/-207F with an average around -55C/-67F. Then it would sublimate away into the atmosphere. Nothing exciting. |
The benefits of cheap, free, limitless energy (fusion or otherwise). | Well if we could produce free energy, there are a lot of large implications. It would completely change the political landscape. Would the west be so interested in what's going on in the middle east if there was no oil? Would the relationship between Russia and Europe be the same if Europe wasn't relying on Russian gas... |
Why do some animals produce offspring normally while in captivity, while others produce offspring very rarely or not at all? | Stress. Imagine being locked in a cage with the opposite sex while people came and stared at you constantly. Exactly how randy would you be? Some animals won't be stressed by these conditions, arguably due to differences in cognitive abilities. Thus, they are still willing to mate. |
Why have we only just discovered Proxima Centauri B, despite discovering thousands of other exoplanets hundreds of light-years away? | Because it is relatively small and most of those other exoplanets we've found are supergiants. Planets so big they significantly block out the light from their star, or even shift their star in space, are much easier to find than a smaller planet even if it is a lot closer.Astronomer here I can explain. The majority of... |
How do photographic memories work? | Photographic memories have never been demonstrated to exist. The term you are looking for is eidetic memory. Hopefully someone will chime in w/ the specifics of that. Edit: Since nobody is coming along to answer this. Eidetic memory is still open to debate and study. It typically occurs in children and then goes away a... |
How can something like solving a rubik's Cube have a world record when there's a chance of getting a easier pattern to solve than others? | *Any* arrangement of the squares can be solved in 20 moves or less, so it doesn't really matter what you're given. |
How can a photo look so perfect in the viewfinder, and then look like crap in the photo? | There are a couple things going on here: 1. The film or the sensor in the camera reacts differently to light than your eyeball does. 2. Even with an SLR style camera what you're seeing through the viewfinder is going to be different from what's actually going into the camera. 3. When you're walking around looking at st... |
Would a vegetarian man's feces make good compost? | It doesn't matter vegetarian or not. Any human feces must be composted at high temperature for 6 weeks before it's safe to use as fertilizer. Even then, don't assume I'm right, ask an expert.Human feces does not make good compost or fertilizer because of the risk of spreading diseases. Diet does not matter for this, it... |
How do capacitors work? Why do they explode? | The simplest capacitor is two metal plates separated from each other by something that doesn't conduct electricity . They store charge because when a voltage is put across them, this causes some of the electrons on the positive plate to move to the negative one. If you then disconnect the capacitor, the electrons stay ... |

Flying in the downwash is harder, and flying in the upwash is easier, which is ... |

A match stick is solid so blowing on it only serves to reduce the oxygen.You can blow gently on any smouldering material and get it to flame. If you had ... |
Why yawning affects hearing? | The Eustachian tube is connected to the ear and the mouth. The air can get right into the inner ear.

For mammals pretty similar to humans like pigs, rats, and dogs, it probably has a relatively similar effect. Their brains have all the same "circuitry" that exists in our brains that is impacted by THC and alcohol. They also digest stuff similarly so alcohol would get into the system in a simi... |
