 If hypertension is bad, then why is exercise a good thing if it also raises blood pressure?

It's a temporary increase, which is fine. It's when your blood pressure is *always* high that you have a problem. Exercise has many benefits which far, far outweigh a brief increase in blood pressure.

 What is Bose Einstein Condensate and how does it look like?

Imagine a classroom with three rows of seats. Suppose for example, that there are 3 students in the first row, 5 in the second and 6 in the third. This is called a distribution, one of students into rows of a classroom. We do the same with particles and how they arrange themselves into various states in a system. Typically this is the energy level, however an energy level can be called degenerate if more than one particle occupies that certain level at the same time. In the above classroom example, if you only looked at rows, all three rows were degenerate because they had multiple students in them. However, if you looked at individual seats, each seat had either one student in it, or none (a free seat), so no seats were degenerate. Now, as far as this *distribution* of particles into states is concerned, we have two behaviors, two different distributions. One is the Fermi-Dirac distribution, and the other is the Bose-Einstein distribution. These are both functions that describe how many particles occupy a certain level, and they vary based on system temperature. These two different behaviors and distributions give us two types of particle, one that obeys one behavior and another that obeys the other. Consequently, we have *fermions* for the first, and *bosons* for the second. Turns out that the key difference between these two types of particle is a quantum property called spin. Bosons have a spin expressed by a whole number (integer), while fermions have "half-spin" (1/2, 3/2 etc.). The reason why the distributions are different is because fermions cannot occupy the same "quantum state" as another fermion, while bosons can occupy the same state, multiple at once. By quantum state we mean a full description of a particle's current "properties". The first is energy level, so on a first approximation fermions will have to avoid having the same energy level as other fermions. They can occupy the same level, but only if all fermions on that level have different values of spin. Further, if they can be differentiated by another quantum property, they could also have the same spin, as long as that other property differs. Bosons don't have this restriction. A certain energy level can be occupied by any number of bosons regardless of their spin. It's a bit like allowing the seats in a classroom to hold more than one student at a time, and, in fact, potentially an infinite number of students in a seat, with no upper restriction. The reason why temperature comes into play is it changes the distribution of energy levels. Normally, each particle wants to occupy the lowest energy state possible. Note that fermions can't all just go to the lowest level because of the exclusion principle forced onto them, so they will only go to the lowest state that is *unoccupied* by another fermion, and you get a stack of energy levels. Bosons however could all simply go on the lowest energy level. The existence of a nonzero temperature, however, provides vibrational energy that allows particles to occupy higher states, even if the states below them are unoccupied. So the entire distribution shifts towards higher energies. A Bose-Einstein condensate is, as described in the previous paragraph, when a system of bosons is at almost zero temperature, and thus nearly all particles are allowed to occupy the same lowest energy level at the same time. It's as if the all 14 students in the class were in the first row, even though the first row only has 5 seats. Or, if considering a per-seat level, having all 14 students in the rightmost seat of the first row.

 Why do two almost neutral components (salt and ice) suddenly start being corrosive when the salt touches the ice?

I think you're referring to people putting both salt and ice on their body, leaving a scar behind. Basically, the salt lowers the melting point of the ice substantially. When the ice starts to melt, it withdraws heat from its surroundings (also from the skin), thus lowering the temperature of the skin and leaving a frostbite scar behind. It's not corrosive though.

Calories isn’t what goes into your stomach. It’s the types of food that makes you feel full. Cheetos (I don’t know if you’ve noticed) break down easier than most other foods. These snacks that are filled with calories will be metabolized and used quickly compared to denser foods. (Simple v. complex carbs)

Economics or function.

Likewise, plastic packaging for food items might be too porous with more environmentally-friendly plastic, thus removing the benefit of the shelf life of the product.

 How does Planet Earth get all these insane angles and right next to animals without disturbing their natural choices?

I make wildlife documentaries. This is an answer that I cut and pasted from a previous thread. I can't really say too much about long lens stuff cos I specialise on invertebrates. But for them what you do is use a mixture of sets and wild shot footage. You have certain things that you can't film in a studio and other things that you can't film in the wild. This is an example of the [former]( URL_0 ) And this the [latter]( URL_1 ) Say you want footage of the inside of a nest. You won't be able to get this in the wild without disturbing the animal. So you need to construct a specially made tank that will allow them to be calm relaxed and go about with their normal behaviour, but also allow you to light it and get good camera angles. The footage of the wasp in the tunnel in this [film illustrates]( URL_2 ) this. What I did was cut a sample tube in half, fill it with sand so it looked natural. Then stuck it to the side of an opti-White glass tank. Kept it in the dark till the wasp got used to using it, then once it had I just filmed away. Another big thing is editing. You can use careful editing to make it look like the animal is seeing something that is not actually there. For example; the scene of the harvest mouse in Planet earth two, when it is being hunted by a barn owl. The mouse was almost certainly shot in a set and the owl in the wild. The two bits of footage were edited together to make it seem like the owl was hunting the mouse. When in reality they were probably shot days if not weeks apart. Edit: I thought I would include a link to [this video]( URL_3 ) which has a sort of making of bit at the end.

 Why do you humans have to crawl before they can walk? Most animals start walking shortly after birth.

Humans have two big adaptations: Big brains and upright walking that allows the use of tools. But upright walking favors narrow hips while big brains require big skulls, and the skull must pass through the hips at birth! To balance these two things humans are born relatively early and undeveloped, requiring care from their parents (which can be done with our big brains and tool use).

 If i scramble a 3x3 rubiks cube 10 times, will they all be the same difficulty?

If a move consists of rotating one slice, and you can rotate it 90, 180 or 270 degrees, then I think there are...27 possible moves? x1, x2, x3, y1, y2, y3, z1, z2 and z3, and three amounts of rotation for each. So a dumb estimate would be that there are 27^(10) move combinations you could apply. The catch is that many of these are equivalent, or could cancel out. Turning a slice 90 degrees, and then turning it 270 more degrees (or -90 degrees) results in no change to the cube state. And there are other combinations, like turning the middle slice 90 right and then the bottom slice 90 right is equivalent to just turning the top slice 90 left. So if you applied 10 random moves, in some cases you might get a bunch of moves that cancel each other, and that could result in a cube that's closer to solved. It may not be *obvious* that it's closer to solved, unless you have a lot of experience, but definitely some random scrambles would seem to do more than others.

 How's hacking really done? The movies make it seem so simple

Typically it's exploiting human error, like phishing links, where a fake email will get a user to type their information into a duplicate website. However, the more interesting way hacking is done is by exploiting holes in the software/hardware security. Like typing code into an input that is then ran by the system, which can then reveal private data or give insight into other kinds of attacks. Sometimes there is oversight in actual hardware, where private bits can be cached in accessible registers. It's very case by case how hacking is done, however, sometimes that case exists in a lot of machines or a single breach reveals a lot of information.

 Why do some older recordings of songs have different instruments coming more prominently from either the right or left of my headphones?

I know what you're talking about. Others commenters are thinking about normal stereo mixing, which is pleasant. Some old records (with original mixing) have a very radical separation, like guitars 100% on one side, vocals in the middle, drums 100% on the other. It's annoying. IIRC, some original or "remastered" long ago Beatles songs sound like that. My guess is that stereo was a novelty, and people didn't quite know what to do with it; they wanted to make sure you noticed it was stereo, so no subtleties.

 Is 'Calorie in, Calorie out' accurate description of human digestion? I'm thinking that food passes through the body at a relatively steady pace, so if there is more food then all the food has less time to process, right?

Like many things in human biology Calorie in: Calorie Out is a big over simplification. Technically you can accurately measure the calories in any food item. You take it and burn it in a device called a calorimeter. But human bodies are more complex and messy. The problem is we all metabolize food at different rates. Food actually doesn't move through us at a steady pace. It varies from person to person, and even day to day for the same person. Fiber and fat content can make a difference. Then the calorie out math is even fuzzier. It takes more calories for a 300lb person to walk a mile than a 160lb person. So if you're walking on a treadmill and it's giving you a calorie count, that's a rough often optimistic guess. Some people burn more calories at rest than others. Your metabolism can do wacky things to conserve energy to keep you from loosing weight. At the end of the day loosing or gaining weight comes down to calories in vs calories out. But what a calorie is in the lab vs the real world is more complicated.

To put it simply, there's 2 factors, the way the atmosphere is constantly moving and creating changes in pressure, causing the air to move from areas with higher pressure to areas with lower pressure (think of it as a giggling balloon), and then there's the effects caused by the spinning of the earth itself.

You could elect yourself CEO. You could elect whatever board of directors you wanted to help you run the company.

The iron deposits we find in the ground is just fine. Even refining the iron ore to iron metal does not contaminate it, mostly because this process uses fossil coal. The problem is that converting the iron to steel involves pumping compressed oxygen into the molten iron to make it react. And the compressed oxygen is made from the atmosphere and is therefore contaminated with various different isotopes. Most notable small quantities of cobalt-60 which binds to the iron in the steel.

No. If you pick 5 cards ouf of a fresh deck, your odds get better with each pull. First pull: 1:52 chance. Second: 1:51 chance. Fifth pull: 1:48 chance. If you put the card back and reshuffle each time, assuming you really do shuffle randomly, each pull is a 1:52 chance.

 Why don’t ionic compounds ever exist as molecules?

Ionic compounds and molecular compounds are distinct phenomena - ionic compounds are held together by ionic bonds (one atom/ion transfers an electron to another, giving both of them full valence shells), while molecular compounds are held together by covalent bonds (electrons are shared between atoms, giving both of them full valence shells)

 If Iron, Nickel, and Cobalt are the only magnetic elements, then how/why do rare earth metals make stronger magnets?

The rare earth metals are magnetic, but only at lower temperatures. By combining them with iron, nickel, and cobalt in alloys, you can raise the temperature at which their magnetism would normally disappear. The stronger magnetic field comes partly from the high number of unpaired electrons they have.

 What makes it difficult to make flavors that taste exactly like pie, roast chicken, spaghetti and other food of the like?

That's a very broad question since you're talking about a wide variety of foods that all have different flavours for different reasons... But I think a good example of why it can be difficult is stuff like the Maillard reaction. [The Maillard reaction]( URL_1 ) is a reaction between amino acids and reducing sugars that results in browning and produces the chemicals that make many foods taste pleasing when cooked. The thing is that there is not just one kind of amino acid and reducing sugar. There are many different kinds, and when the maillard reaction occurs in cooking, it doesn't just produce one chemical, it produces a whole range of chemicals, and some of those chemicals break down to make other chemicals. Each food can have its own unique maillard reaction with it's own unique profile of flavouring chemicals as a result (leading to wildly different tastes), so to make exactly the same flavour profile you need exactly the right starting chemicals, reacted in exactly the right conditions. That's a lot harder to produce than say, the characteristic flavour of pears, which is mostly down to mixing together one specific carboxylic acid with one specific alcohol to get [one specific ester]( URL_0 ). The Malliard reaction is just one case of a thing that creates complex flavours. Any taste that involves the interaction of many different chemicals is probably going to be hard to recreate synthetically.

 What does it mean to refinance? A car? A home?

Essentially, you're taking out a new loan to pay off your old loans. Using round numbers; say I owe $1,000 on my car, and borrowed that money at 20% interest rate. It's a good idea for me to borrow enough to pay off what i owe if I can get a rate of 5% from a different bank. With a house, say you took a 30 year mortgage at 20% when you movied in. Now, a decade has passed and you've gotten many raises and have a much better credit score. Again, get the new loan and pay off the old one.

 Why do humans have a bigger appetite when they are sleep deprived?

There are a few primary reasons that are thought to be responsible for sleep deprivation munchies. First, a lack of sleep throws several hormones out of wack. Sleep deprivation causes levels of the "stress hormone" cortisol to rise, and some people are "stress eaters." More directly, sleep deprivation increases the appetite stimulating hormone grehlin and lowers the appetite suppressing hormone leptin. This double whammy leads to hunger and eating even more than usual. These hormonal changes are probably the main factors. Additionally, sleep deprivation leads to changes in the brain that cause the munchies, similar to the effects of marijuana. This drives people to eat particularly "unhealthy" foods (high fat and/or high sugar foods like potato chips or cookies). Changes may also occur that hinder good judgment, meaning you have less willpower to resist those cookies, chips, etc.

 Why does a wine glass make a sound when a finger is spun on the top?

Any object has a harmonic frequency at which it vibrates best. For a thin wine glass, this might be a relatively high note which you can hear well. For a tire, it's likely too low for you to hear. When yo run your finger around the edge you stimulate vibrations, but you finger is slippery enough to not require a specific frequency. As a result the vibrations in the glass cause your finger to slip free in phase, reinforcing the preferred tone.

 what happens when you eat the silica gel packets?

The pellets will absorb moisture quite easily and swell up. This may cause some irritation in your digestion system but most of the time it will just pass harmlessly through. It can however cause constipation in small children. The label "do not eat" is not because it is poisonous but rather because it is not intended as food. The small packets may to some people look a bit like candy. But they are not. There is however silica gel which is laced with poison. Some contain a material which changes color depending on its humidity and this is poisonous. But the white silica gel is safe to eat, but not wise.

 what is the purpose of the value e?

The mathematical constant e is referred to as representing natural growth. Unlike other popular constants like pi, e does not have a handy visual to explain it. Instead it can be thought of using banks and interest: (For true ELI5, interest means "the bank will add 'this much' to your money at the specified time) If we have a bank that generously offers 100% interest every year, and you give them $1, then after a year you will have $2. But wait! A rival bank wants to offer 50% interest TWICE a year if you bank with them. At first, you may think that 50% twice = 100% once, but that isn't the case. After 6 months with this bank, your total + interest will be $1.50. Then another 6 months later it would be $2.25, getting $0.75 from 50% of the $1.50. So it would seem that even if the % interest adds to the same 100%, getting it more often leads to giving you more money! So what about a bank that offers 25% interest every 3 months? Or 8.3% every month? How about an inconceivablely small percentage interest at every fraction of a millisecond throughout the year? You'll find that the final amount tends toward the value of e if you were able to gain interest at a "natural" rate of growth. 100% once a year: $2 50% twice a year: $2.25 25% four times a year: $2.4414 8.3% twelve times a year: $2.613035 Every possible moment in a year: $2.71828 (approaching the value of e) e is also important in Calculus and the natural log, but those are waaaay beyond a 5 year old.

Pretty sure that they don't decide, they just insert the winners randomly into the stream of cards printed. They definitely don't monitor them afterwards, because treating any card differently would give a massive clue that its a winner and these things leak quickly.

 How do lasers work, especially the ones that can cut metal?

The laser source dumps energy into a cavity oscillator. That oscillator produces light that's all the same frequency and aligned in a coherent beam. By putting lots of energy into a very narrow beam, you can make the small spot where the beam hits a piece of metal hot enough to melt the metal. Metals are opaque, aso they have to absorb the energy in light that shines on them.

In short, it's a legal filing that formally states that your debt obligations are well beyond your means and that you are seeking the assistance of the courts to either restructure debts to more manageable terms or, if necessary, discharge some debts. In exchange, the courts may order that any non-essential valuable possessions be sold off and the debtor pay off what can be done with what assets one has, and also typically gets a huge red flag attached to your credit history that lasts a long time.

 How does scientist know/theorize that when we are traveling in the speed of the light time will flow slower?

There's a cosmic particle called a Muon. These particles are created in the upper atmosphere when cosmic radiation hits our atmosphere. Now we can also create them in a lab, so we know that their half Life is 1.56 Microseconds. But even travelling at the speed of light it would take them more than 10 half life's to reach the ground. That would mean we should only detect 0.1 % of the total number of Muons on the surface. Yet we detect over 90% when we do this experiment. The only way this can be explained is relativistic time/length contraction as predicted by Einstein, caused by the muons travelling at almost the speed of light

 please explain what Benford’s law is and how is used to detect fraud?

It's a way to find human invented numbers. In a large set of numbers will multiple digits the number 1 has just over a 30% chance of being the first digit in that number. Number 2 has a 17% chance of being the first digit, and each number after that has an ever decreasing chance of being that first digit. Therefore, if you take a very large set of numbers that were generated naturally you should get 30% of all first digits being 1, 17% of all first digits being 2, and so on. A set of numbers invented by a human mind is likely not to follow this law. This is because as humans we have a hard time imagining true randomness. When we ask people to invent random sets of data, they tend to make it so that each number occurs fairly regularly.

 How do you navigate in space?

Navigation and positioning in space (far from earth) is typically done by tracking your position as it relates to stationary or plotted objects like stars or planets URL_1 In summary, you see specific planet out a specific window, this acts as a point of reference, with a few you can triangulate, with computers doing calculations many times a second it can be very accurate. There are other methods too, including Transponder pings, GNSS sattelites, inertial sensing, dead reckoning, etc URL_0 and yes when "aiming" for a specific planet, you actually aim at empty space ahead of it's path, to intercept catch up to it months later on opposite side of solar system at good angle and speed

 Why do athletes take ice baths?

The benefits of ice baths have become more ambiguous since first introduced. At it's primary level, it's pretty self-evident. Cold things will help reduce swelling and possibly inflammation. It desensitizes us to a certain feeling of pain and soreness from repetitive or intense exercise. However, for athletes looking to increase adaptation/strength, inflammation is actually helpful for muscle repair. In a study conducted where people did a 3 month strength training course, the participants that used an ice bath (over gradual cool down) for repair noted reduced swelling and overall soreness but also made smaller gain in muscle mass. Overall, for athletes at their prime, ice baths may be useful for quick recovery between events (i.e. back to back games) but probably not if they want to get stronger long term.

 How do speaker play different sounds at once? Like if you have a bass drum hit and crash symbol, how does a single speaker produce that sound?

Struggling to make this ELI5 but basically the speaker doesn’t produce multiple sounds at once, it creates one sound that sounds like multiple to our ears. Less ELI5: The speaker pushes the air in front of it to approximate how the air moves when the drum and cymbal are hit, it’s only one speaker so as you say it’s can do both at once, it can only approximate them, two speakers gives a better sonic image, but more speakers does this better still. Last year I had the opportunity to work in a studio with a surround system of 29 speakers, with this you can very accurately recreate natural sounds as you can move the air from multiple directions at once, not just the static position of one speaker.

 How does a breathalyzer test accurately measure someone's blood alcohol content? Since a breathalyzer is an oral test how does this device measure the content of alcohol in your blood?

The key to a breath test is Henry's Law. While Henry's Law doesn't have to do, specifically, with alcohol, for the purposes of alcohol breath testing all you need to know is that Henry's Law basically says that at any given temperature, the ratio between the concentration of alcohol in the blood and that in the alveolar air in the lungs is constant. The easy way to think of Henry's Law is a can of soda. At a given temperature, the space above the liquid in a can of soda will fill with a certain amount of carbon dioxide that escapes from the liquid below. With an alcohol breath test, think of your blood as the soda, and the air in your lungs as the "space above the liquid" that the alcohol in your blood escapes into. This ratio is pretty much universally set at 2100:1 in all breath machines - meaning 2100 parts of lung air contain the same amount of alcohol as one part of blood. The breath machine detects alcohol in your lungs, and then calculates how much would be in your blood based upon that reading. There have been some studies that show that this ratio is not the same for everyone, meaning that a breath test could possibly overestimate or underestimate someone's actual blood alcohol content. But for the most part, it's accepted as close enough to accurate, and that in most cases it actually underestimates blood alcohol content rather than overestimates it. There are plenty of other issues with alcohol breath testing, and I didn't get into HOW the machine reads the amount of alcohol in your breath, but this is basically how the machine takes alcohol in your breath and correlates it to alcohol in your blood.

 How do we know that plastic takes 450 years to break down in the environment if we haven't lived so long to test it?

Extrapolation. We look at a piece of plastic at X time intervals and take measurements, then apply that information to what we know about how things decay (Surface area vs volume, etc). The combination of the two gives us an approximation. It might not be 450 years, it might be 200 or 900. The point is more about the time scale over which the material will break down. Meaning that it's not going to just be a month or two like organic waste, but also not tens of thousands of years like radioactive waste. & #x200B;

 Why software developers use error codes and not just say exactly what is wrong?

Error codes report on the specific fault or symptom, not "what is wrong". An error code that translates to "Couldn't connect to server" for example, means that *for some reason* the program couldn't connect. What exactly is wrong in that scenario? It could be that your internet connection is down, the server is down, both are down, you turned off your wifi antenna, there's a memory leak in the program's net code, the net code is poorly written, and many, many more possibilities. So often, the error will be accompanied by *common* "what is wrong" causes of the error code "Check your internet connection, check your firewall, server busy/try again later, etc."

 What repels electrons from the nucleus?

The electron is definitely pulled toward the nucleus, but the closer it gets the faster it moves. The trick is that the electron gets faster *fast enough* that it doesn't really get a chance to interact with the protons in the nucleus. There's a sweet spot a little ways out where it's *much* more likely to be found. That said, the "classical" model of the electron as a little planet isn't really useful anymore. It's better to think of a cloud of where the electron *could be*, which is denser where it's more likely to be. The cloud is very very thin inside the nucleus, and very very dense in a ring around the nucleus — that sweet spot. They're isn't really an "orbit"; the electron just zooms around inside the cloud.

 how do skateboarders not always break their legs when dropping to the ground on a skateboard from 20 feet high?

It has to do with vectors (direction of travel). Very few skateboarders (if any) can actually take a 20ft vertical free fall and be ok. In any sport with competitive jumping vehicles: motocross, snowboarding, or skateboarding, the trick is the landing ramp. Horizontal momentum + vertical acceleration from gravity = diagonal vector. The landing ramp is intended to match this vector as best as possible which allows the rider to make contact with the ground without going splat. When going over big jumps one of the greatest hazards is “casing” the jump either over shooting or under shooting the landing ramp which makes you go splat. *Splat* URL_0

 How do air traffic controllers/pilots choose which runway to use?

The main motivation is wind. Taking off or landing with a tailwind uses much more runway length. It's like having to run to catch a train that's already rolling away - don't run off the end of the platform. Crosswind is more challenging and can upset the passengers (because you takeoff or land tilted). In poor visibility, you might have better instrument approach equipment on some runways. So weather decides which runways can be used to begin with. Then you have to arrange the traffic patterns so they don't interfere with each other - more of a challenge at a large airport. Pilots must *always* have the option to return after takeoff if there's a mechanical problem. And to skip landing if they're not lined up properly or the wind does something unexpected or there is a traffic jam on the ground or, really, anything. Small airports, pilots might ask for and usually get a specific runway. If it's too small for tower control, they'll decide on their own! It's quick and easy to turn around in the air, so wind is the biggest factor.

 Why did many countries reported huge drops in GDP and all time high in unemployment whereas the financial markets seem to have already recover ? What's behind the difference between the financial markets and the economy ?

It's a common misconception that the stock market reflects the economy. All the stock market does is reflect people's perception on how publicly traded businesses will fare in the future as compared to today. While yes, there's usually a correlation between the two, that's not always the case. And furthermore, the health of publicly traded companies does not always reflect the overall health of the economy.

 Do insects store energy in the form of fat? Do they even have fat on their body at all?

They do!! I had a professor who mainly studied the neurological physiology of mainly invertebrates and roaches were used in a handful of our labs. He's said that females tend to be 'fattier' so to speak, than males. The fat is all internal and surrounds their organs. Adult insect growth is physically limited to a certain extent by the size of its exoskeleton, so insects arent really capable of reserving significant fat like mammals.

 Why does the Fed adjust the funds rate, and what does it typically mean/signal for the economy?

The Fed Funds Rate is the primary -- and easiest -- "tuning knob" which the Fed can use to try to influence the economy. Raising it means that they are worried more about inflation than they are unemployment and economic growth. Lowering it means they are worried more about unemployment and economic growth than they are inflation. Normally these adjustment are small and highly telegraphed (they don't like investors to ever be surprised!). They become newsworthy when they think that they are worried about inflation so much that they might actually trigger a minor recession with their rate hike... or if they end up lowering the rate super low to near zero. Once the rate gets to zero the Fed is "out of bullets" and extraordinary measures might be needed the next time around.

 can bacteria be killed by contact and friction?

No, that's not quite what's happening. The whole point of brushing is to remove food. Bacteria feed on the food and release acid, which eats away the teeth. Brushing is removing their food source primarily, any bacteria that are incidentally removed as a secondary benefit return eventually, since our entire respiratory tract, oropharynx, and entire body are constantly colonized by bacteria...but without a ready source of food, they don't excrete as much acid, and don't proliferate as much overnight. As to whether bacteria can be killed by friction and impact, that's an good question, but I would guess almost certainly not, as the pores and microscopic recesses on our hands and surfaces offer ample room for bacteria to blend in and be protected. They are really, really small and fit in microscopic crevices. And, they are flexible and fluid filled, and can probably take a beating... Imagine an orange on a mattress...you can probably hit it as hard as you like, it will just sink into the mattress and deform a bit, but pop back.

 How do fireworks have direction, like in the case of fireworks that create hearts or smiley faces?

When you see these designs in the sky, you're actually seeing a group of firework shells exploding at the same time. A firework display uses hundreds of launchers at a time in their shows to get the effects you see. For example, a heart shaped image can be 10 different fireworks exploding at the same time. They are shot into the air at different times and from different launchers. They each use a different amount of chemicals to launch them to a certain height and they explode at the same time using microchips. If you're close enough to the launchers, you'll hear multiple fireworks being shot into the air but only one explosion. There's a lot of chemistry involved in making the fireworks but technology and computers go a long way when it comes to the actual fireworks show. Edit: I forgot to add that there are also special firework shells made to make shapes. If the image grows bigger in an outward direction, a special shell is made with different ingredients that ignite as the shell explodes. There are many different ways to get different effects. It just depends on the company putting on the show and what the people paying them want.
