Superheated water

[LVgunbox]

Fail !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!­!!!!

cleaner water, bigger then the boiling temperature

Making the water dirty, of course, that it will begin to boil.

[scrotty11]

it also works with putting in tea or coffee or dirt etc etc

[Mrcrazydemon115]

Sugar does not act exothermically when added to boiling water. It usually absorbs some of the heat from the water for thermal equilibrium to occur. Enthalpy of solution suggests that when a measured solute is added an endothermic reaction will occur. THE TEMPERATURE OF THE WATER WILL DECREASE.

[tm01940]

this is fuckign tight man i;m gonna try this and steal some distilled water from my chem class bros!!!!!!

[cplover12321]

waiting..waiting waiti- HOLY SHIT

[Jigsaw5435]

THE WATER IS PISSED

[pandemonic01]

@Jigsaw5435 it's rage has truly hit the boiling point

[TimothyOng98]

erm... actually no the sugar serves as a nucleation sorce an the water whicj is over 100 degrees boils. it only happens when the vapour pressure of the water is greater than the ambient pressure and the bubbles tt appear when boil just disappears. read it up.

[sh4p3shifter]

poor water

[FOXRACING2714]

how long do you put the water in the mocrowave for ???

[9234The]

i have 2 full bottles of distilled water i thought i only had one lol no im wondering where the second one came from i cant remember lol.

[noraneka]

with me it's different. when i used drinking water , microwaved it for 3 mins , 30 secs in a tall glass cup, and put 1 tablespoon of Sanka ( instant coffee), it made a more of an volcano eruption , instead of an "explosion". can anyone explain this?

[AZMALING]

I tried that with mentos, and the mentos was gone within seconds

[Arthur61987]

"stick your dick in there and see what happens" got that many thumbs up? I refuse to believe I belong to this species...

[sam9072000]

@PKTproduction water have oxygen and am i taking wat your saying the wrong way?

H2O and 2 hydrogen atoms and 1 oxygen atom

btw my bro discover that when you open a coke or sprite and add lots of suger and it bubble, try for yourself

[SuperSoccerSpeed]

hahahah i laugh when i see this

[davidiscoolnotschool]

that looks so normal maby that is the water they use to melt witches.

[Kibbleis]

I would drink that thinking it was normal water.

[darkflames9]

A lot of people have some.... Interesting.... Theories as to why this works :P

[iNicoTECH]

just boil water alot of time. then pour shit to it.

[staticfive]

Gotta be distilled

[k0namiman]

Why this happens.

Distilled water contains no impurities. Or, in sciency terms, no nucleation points. There is noplace for bubbles to form in the water. This allows the water to be heated above boiling; boiling water never gets above boiling because the bubbles carry away the energy as fast as you can put it in.

So water here is above 100 celsius. And the sugar is poured in. But it could be anything; what it does is provide a nucleation point. Lots of them. The water now can form bubbles, and >

[k0namiman]

the excess energy is released... all at once. The result is an eruption such as this. And it can happen if the water is microwaved, or heated over a stove. It is a real problem, so chemists dealing with heating distilled water in large volumes usually use what is called a 'boiling stone' which provides a nucleation point.

[rotaryengine1]

i wish more ppl were like you and use there mind to research and learn the real deal on things in this world. i feel good when i see someone passing on GOOD, non misleading knowledge to others.. keep up the good work.

[elitechrstn]

@k0namiman

Thank you! some one on youtube that can actually explain something and back it up.

I just got through yelling at some dumb ass who called me a dumb fuck because he says Lightning is not a plasma lol. what a retard

[FearfulAssassin]

impurities lower the chances of water being able to superheat but its not impossible to superheat it if nucleation is minimal.

[danagol1985]

Is there a temperature limit, for superheated water. I mean ovbiously it is above 100*C already, so how much hotter could it get, and what would happen?

Is it possible it could get hot enough to melt the glass, that would be strange!

[Joelyboy83]

The water can be heated up to its critical temperature (374 degrees C) so unfortunately not hot enough to melt most glass.

[yayMikester]

Cool, can i do that with my pee?

[piegames1]

if you boiled it repeatedly. then yeah. but it would just be water... the urine would get boiled out of the water

[DrLsw]

if you make it into pure distilled water first

[kriptonis]

lol. nice.

[FERENCEFF]

When water boils it creates bubbles of steam. That is it goes from the liquid to the gaseous state. This carries away heat energy and holds the water temperature stable.

[MysticKnight38]

HAHA I can do that with warm water and Costic Soda

[dukcaboose]

for those who dont understand...

i'll say it in easier words.

distilled water does not boil, because it has no impurities, but tap water does boil, because it does contain impurities

the sugar acts like an impurity for the distilled water and makes it boil right away if the distilled water has been heated pass the point of regular boiling point of water

(212 F, 100 C)

[chreyer]

I'm pretty sure no? Pour sugar in hot lemon tea and it won't suddenly bubble :p

I think what you mean is similar to burning sugar and producing carbon dioxide? To burn something you need a source of heat - which I don't think the water is high enough, source of fuel - sugar I guess, and source of oxygen - none in water

[padrinoel]

@chreyer it was distiled water. it has nothing to boil. when its heated over boiling temp and you add anything to it, it now has something to boil and BOOM

[Bionut1192]

@chreyer, actually what happens is that distilled water has NO edges for the air bubbles to leave the surface of the water from (eg the minerals in the water) and adding ANYTHING to the water will instantly cause all of the air to escape the container. There's an article about it on cracked..

[torakokoneko]

@chreyer hot lemon tea isn't distilled water, now is it?

[d0861]

LOL

[Mrmatz85]

Science fail...

[summerboyfun]

@PKTproductions you idiot

[yamuma8666]

@PKTproductions Are you retarded???

[glaked23]

yeah i've heard that but tbh if you stop and think about how a microwave works then you should know it does more than heat water up.

[zackcyboy]

When you add a solute (sugar) to water the sugar gets in between the water molecules. The water is more "disordered" and can evaporate (boil) easier as the water molecules are outcasted from each other making it easy for them to escape into gaseuous form (water vapour)

[d0861]

You are correct, sir. I find it amazing that so many people cant comprehend the basic principals of chemistry.

[zackcyboy]

Ya learned it in chemistry class. Simple stuff really.

[Gunner3210]

@zackcyboy Except you were an idiot and didn't pay attention in class. It is not simple stuff. Go back to school.

[zackcyboy]

what actually happens is that water has a boiling point of 100 degrees and when you add sugar the boiling point dropes to maybe 70 degrres. The water he had was probably at 90 degrees. When you add the sugar, the boiling point of the solution goes down and as soon as you add it, the water all starts boiling because of the new boiling point which it surpassed when it was pure. Learned this in chemistry

[chreyer]

I also measured the temperature of the water using a digital thermometer as this was for a chemistry project

the measurement wasn't very accurate because once you stick in the thermometer in the water the temperature starts dropping really quickly, but I did achieve some readings that were over 100 degrees.

[zackcyboy]

the boiling point of water changes with the pressure of the enviroment. Where i live the pressure is around 94 kpa in the winter. Water boiles at exactly 100 degress when the pressure is 101 kpa(kilopascals). Getting water to boil at exactly 100 degress is highly unlikely

[chreyer]

You are correct, but what happens here doesn't really involve pressure. When you heat water in a microwave the water is heated uniformly. Once the water reaches the boiling point, and if the water is pure and there are no cracks in the glass, the water won't form bubbles like you see when you boil water in a pot (start of video). Without these bubbles, its hard for the water to transfer heat away and so it just gets hotter. What the sugar does is disturb the water and so bubbles form.

[zackcyboy]

On earth there is always pressure. 6 km of air are resting on your body. Just like in water when you go too deep your ears pop because of the water pressure. The same with air as there both fluids,but air is less dense so you don't really feel the pressure. The rest of the stuff you said is correct.

[DerivativeXY]

@zackcyboy yeah man its called boiling point elevation and freezing point depression. Adding solutes to a solvent will change its boiling and freezing point due to colligative properties. This same concept is used when salting the roads in the winter.

[teachrz2]

Might want to review that topic. The colligative properties of water show that dissolving a solute in water (like sugar, salt, etc) depresses (lowers) the freezing point and elevates (raises) the boiling point. This video shows superheated water (above the point at which it is expected to boil). Adding most anything provides a surface upon which boiling can occur. This is why it's dangerous to warm pure water in a microwave. Put your sugar in first (or any other solute you wish to disslove).

[pureskill13]

@zackcyboy no way learn your science buddy -.-

[a564102]

@zackcyboy Correct me if I am mistaken, but as far as I remember, adding sugar (or salt, or whatever) will actually raise the boiling point.

[Gunner3210]

@zackcyboy You learnt it wrong in chemistry. Impurities in water RAISE the boiling point. Not lower it.

[tritikar]

@zackcyboy

sorry buddy but adding sugar or salt for that matter too water actually increases the required temperature in order for the water to boil, not the other way around as you suggest.

[GapToN]

@zackcyboy actually its not about boiling point its about physical disruption. if you put a stone in it it will have the same effect. Once the super-heated water is disrupted from its stationary state, all the excessive heat makes the water boil instantly. Same reaction happens when you hit the glass with a spoon, grab the glass and thus shaking the water inside (and get your hand burn)

[swimmingrules1234]

@zackcyboy no. you're stupid. the water is superheated and has a temperature beyond the boiling point. thermodynamically, the vapor is more stable. kinetically, the liquid needs a path to reach the vapor phase. this means that the water needs a nucleation point so that vapor pockets/bubbles can form. salt provides the nucleation point.

and anyway, the phenomenon is "boiling point elevation/ freezing point depression:" adding sugar *raises* the boiling point

[0987654321284]

i tried arrowhead and the water exploded inside my microwave after 6 minutes.

[1nm1]

Also can happen sometimes when microwaving water, like for instant coffee

[ProgHead777]

This CAN happen with tap water. It happens to me all the time, though, not quite as violently. You have REALLY overheat it to get it to explode like that.

[Elphieunderstudies]

this is why its dangerious to heat liquids. because they can spatter and expload upward burning your face if disturbed.

[rushrox777]

Yep, it doesn't work wtih tap water..:( Damn...

[Slench101]

wonder what would happen if you mixed supercooled and superheated together... would it explode in some sort of way or would it neutralize itself???

[LoyalSol]

It would be a similar effect if you put boiling water into water that is near freezing.

[pl0xinat0r]

it's not an ion, it's 2 different temperatures, the super cooled would just heat up too fast to actually cool.

[scienceminded]

I say we stop the speculation and just do it, it's only as hard as mixing the two types of videos, taking all of 10 minutes to perform....hmm this gives me an idea.

[TheRandomIndian]

That's kinda physically impossible. If you put microwaved distilled water into a freezer, the temp. of the water will drop and probably not freeze even under 0 degrees (it still is pure). You can only do one or the other..

[rushrox777]

Can't wait to do science in secondary school :)

[Arctikes]

don't try now

[Arctikes]

Sorry I meant: don't, try now

[rushrox777]

Ok i will!

[sassysilver20]

wohoo

[shadowruler24]

u sound like a scientist

[Peacemaker636]

For water to freeze or boil, it needs a nucleation site. When water boils, it is simply hot enough to heat bubbles that are already in it so much that the air pressure inside the bubble equals the atmospheric pressure. Because the pressures are equal, the bubble does not collapse and will rise to the surface.

If the water is distilled and in a smooth container, there will be no (or very few) bubbles because there is nowhere for air to stay trapped. So, it won't boil until bubbles are introduced

[browneyedgirl1996]

its water past its bolling point it can happen a lot in microwaves when u put somthing in it it reacts and the water can even explode

[fnawesome27]

loyalSol. it doesn't boil. that's the point. not until there's an impurity

[LoyalSol]

There is a point where the water will boil.

You naturally have vapor pressure from the liquid no matter how pure it is that is governed by chemical kinetics, but the rate at which it will evaporate is incredibly slow. It won't go to a full boil without a site to collect on.

[Kate1527712]

Wait so correct me if im wrong. its clean hot water with suger thhrown into it? how is that so?

[Krnmustang11]

distilled water doesn't boil, tap water always boils because it has impurities, if u add a impurity to a water over its boiling point, it reacts violently, it was a myth busters episode haha

[LoyalSol]

It does boil, but it has a harder time without an impurity to collect on.

[SuperSaiyanGoku2868]

HOLY SHIT,IT ALMOST GOT YOU!

[svengeanse]

yah... ALMOST.

[Sh4n73c]

Hmm.., i've been thinking!

Why it starts to "spill" all over, is because the water itself dont have any more impurities, nor air! So.. if you would put it in freezzzor, would i create so called 'clean ice'?

[coolmancool1234567]

Yep, the ice would be extremely clean! The funny thing is that if you put it in the freezer, it will actually supercool rather than superheat, so the water will not freeze til you poke the bottle or turn it upside down or disturb it in some way

[stephenharperbest2]

now thats lava

[trentcreek]

"Simpsons did it!"

[sandyman002]

Come on. Put your hand in it.

[theftman988]

you do know that water is over 100 digreese celcius

[Daraabstar]

I'm ok but you can go ahead knock your self out and kill all the cells and nerves in your hand

[collegeBoi15]

i discovered this effect by accident on friday.  it was not a pleasant discovery. i burned both hands, fortunately, not too badly. though, i had actually used tap water, so at least some cities' tap waters must work.

[coolmancool1234567]

LOL the city water where you live must be SO CLEAN!

[bigjosh1587]

lol your dumb, or funny, i cant tell

[KanesTemple]

its mad!!!

[lovedevourer]

yah u must put a spoon or any thing in the cup first

[lostboss22]

Its distiled water it wont boil adding any impurities to the water makes it instantly boil

[VJBiohazard]

I do this with tap water in the microwave. I've gotten into the habit of always putting a fork or utensil in the glass before I attempt to use the water...

[Dragondude98]

holy shit

[hilldog96]

wtf

[toolbag1222]

thats why you boil water in the micro with a tooth pick in the glass, gives a good surface for the bubbles to form.

[TerryCPiano]

Won't the glass break when touches the hot water like that?

[BirdValiant]

The water was already hot (above 100 degrees C), it just didn't boil because it was kept so still in the microwave. It wouldn't be good if the glass was suddenly cooled.

[Skoda130]

But that is exactly what happens when the water start to boil: Vaporization draws heat from it's direct surroundings, including the glass..

[isays]

Although this is true, the heat being transferred to the glass from the water is much greater than the any heat loss due to vaporization.

were what you seem to be saying the case, pouring boiling water on someone would cool them off because the vaporization of the water would draw heat from their skin.

sweat cools you down because it is already at equilibrium with your skin temperature, and when it evaporates the energy is drawn from your skin.

[Skoda130]

But does that also count for superheated water, that vaporizes almost explosively?

[isays]

yes. it doesn't "vaporize explosivly" really. it is just already hot enough to be in a very fast boil. when it is allowed to boil, all the bubbles simply form at the same time and splash the water everywhere.

remember, the vaporizing doesn't really "suck out heat", the hot water simply PROVIDES the heat energy to vaporize itself. once enough heat energy is gone from the water, it stops boiling (and therefore stops absorbing heat)

[Skoda130]

But some old engine's use vaporization to cool the engine. (The ols stationary ones)

[isays]

that is because the engines heat the water enough to boil it. because once water begins to boil it does not heat up, the temperature difference between the engine and the water ensures engine heat is being transferred to the water. the more heat you put in the water the faster it boils and therefore the faster it dissipates heat.

the vaporization is not really "sucking the heat" out of the engine, heat is transferred from the engine to the water due to temp diff, causing the water to boil.

[SorthNarolina]

lol i applaud your patience, good job, you make youtube a better place!

[lovelaz95]

Yeah thats erally dangerous but a good stunt all the same. What happens when normal water boils is the impurities cause it to bubble. When there are no impurities, the water is superheated but has no bubbles so if u stuck ur finger in it, u would get really badly burned, and if u drank it.....lets just say u would be stuffed lol

[ccricers]

I'd be cooler if you just filled enough water so that the glass would be totally empty by the time the explosion's done.

[laparis08888]

LOL

[TACOHEAD8835]

What would happen if you stuck your finger in the water?

[HieiUmbra]

It would have the same effect, but your finger would be horribly burned, that water is above the boiling point, but since it doesn't have any impurities to cause the bubbling, it looks like normal water, when agitated it bubbles like normal boiling.

[yoohoomsn]

wat would happen if you drank it??

[bobbywilson09]

are you retarded?

[GRAVEYARDSK8]

LOL YOU GO BOOM

[riteflite]

do it with sodium chips and tell me HOW much fun you had yuk yuk...but really DON'T do it!

[greencity127]

HAHA LOL DANGEROUS

[rappinrobot8]

omg sick

[Karnardo]

omg f*ckin nerds

[ryanguitarman]

actually, this is just distilled water thats been heated past the boiling point of regular water

adding any impurities causes the water to instantly boil them away

[KrispyKangaroo]

Yes, though it's not the impurities that actually causes the boiling over, it's the air that comes with it. Impure water can be superheated, but all air pockets must removed.

[2jz4fun]

never put that hot water into a glass it can explode to pieces...thats what happened to me when i made my tea

[GreenDayLanArmstrong]

Yea ... and me too :( :)

[actrol]

me three

[funnyasdeath]

me eight

[BugsHaveProtein]

should have put in some sodium...

[laurdy]

no he should have put caesium or francium in there!

[poopopoop]

or maybe just an m80 lol

[actrol]

were would he get francium frm?

[emby721]

To put it bluntly, he wouldn't. Francium is amazingly rare, it has a half life of 28 MINUTES and if i remember correctly there is no more than 250 grams of it in the earths crust at any given time.

[laurdy]

i said caesium or francium because if i put just caesium someone would put something like "dont you mean francium" and if i put just francium then someone would put something like "francium has never been isolated in visable quantities"

[fairyglade]

yeah i saw this on mythbusters...something with distilled water.

[MediaNexus]

Liquid nitrogen produces a dense vapour cloud and would also freeze the outside of the glass. Go to school.

[Bartello]

stfu deathhell77 U are the dumbass, thats superheated water, over 100 degrees. if u put sugar or something like that it will cause a violent reaction.

dickhead

[michael853]

i have seen this before on TV.. about explodeing water

[Spocko000]

how come the glass didn't crack?

[chreyer]

Not enough force, the water is just bubbling at a temperature over its boiling point. And if you blew bubbles in a cup the glass would not crack either :p

[na626]

there is a a place for the water to leave there is not enough pressure

[stormbringer9]

lol

[TheBrassSectionRocks]

You got yourself a volcano.

[seahyimin]

lol looks funny

[TokoDragon]

yeah, it has to be FREE of minerals/impurities in the water (Which is what Distilled water is) so there is NOTHING in the water to boil as it is heated up in the microwave, so if it's heated, then you move the molecules it gets the molecules moving and the distilled water will quickly evaporate. Same works for super cooling

[FullMentalPanic]

now imagine if someone put that directly to his/her lips...

[lopek77]

u ARE a bit mental u know

[need1more1sugar]

i know what would be even more fun in your pants :)

[benddr140]

cool

[mylogon341]

GOD! the reason water boils in a pan/ kettle is down to convectional current caused by the heat from below. when microwaving water, you don't get the same effect as it is heated up from 'microwaves' so it heats up all together from no particular direction. after taking water from a microwave that is 100 degrees celcius and slight agitation causes the particles to 'flip out' and 'boil'. not sure what the relivancy of the sugar was. this is what i was told anyway...

[astroboy1979]

the sugar just stirs up the water frum sever hundered directions (each grain) so its more spectacular.

[astroboy1979]

u could do it with anything, sand, forks, shaking, fingers etc. just disturb the molecules enough to react

[poopymcdoopy]

LOL, "fingers"

[lkjkorn19]

haha fingers would be painful though I guess

[jroshau]

its when water goes over the 100 degree temp and once u desturb the surface area of the water it reacts annd well u see what happens, i bealive it has to be distilled because boiling water is getting rid of the impurites and if there is none there are no impurites

[bulletwing]

to get best results, boil some water in a kettle a few times, then when it is cool, put it in the mircowave for a couple of minutes

[lordhathor]

what exactly was that?

[NikoKun]

microwaved water... this just happened to me today... I microwaved some water...and the moment I moved the glass out of the microwave... the water exploded and turned into steam... >_> I'm lucky to not have burns...

Lesson: dont microwave water...

[UncleAlfred51]

You can microwave tap water, though.

If it's distilled water than a few grains of sugar can stop that from happening.

[SefoKaya]

why isn't the glass affecting it? Why must it be sugar?

[Envergure]

Because the glass is so smooth. Unless there's a scratch or some other point sharp enough to trigger the water to start evaporating it stays a liquid.  Likewise, you can freeze water to -40C and it won't freeze if it's pure enough and the container is free of defects.

[SefoKaya]

That's... amazing. Good to know, thanks :)
