It is called the Gay Lussac's law, or pV = nRT, when the candle lights off, the temperature falls down (T decreases). V is constant, therefore p decreases. The water goes up pushed by the atmosphere
@kassem435 OMG are you stupid or something ! the main goal of the experiment was to show the water being sucked up by that glass......It's not rocket science
@YoungPhoenixFire No... The fire heats the air which makes it expand. When the flame is extinguished, the air cools and condenses. The size of the air mass shrinks which creates a vacuum and sucks the water into the flask.
@skipplet Dude, have you ever heard of the fire triangle? Fuel (The wick) Oxygen (The air) and Heat (Ignition source). The air doesn't expand, it gets used up by the fire to keep the flame going. which is why the flame goes out before the water reaches the wick. Cause all the air was burned up. then it breaks down into a form that is less dense than air causing the drop in atmospheric pressure inside the jar, being compensated by a rise in water.
@skipplet Ok, so explain why the water doesn't get pushed out of the flask when the heat makes the air expand and raise pressure? Sounds like you're the idiot trying to start an argument.
Fire or the "flame" in this case needs to burn oxygen to stay alight, with no oxygen there's no flame, which means the pressure has changed, the difference in pressure of the inside of the flask to the outside is different, this is why the water moves up the flask its trying to correct the presure difference, if there was no water at the end of the flask it would simply be air moving up but u wouldn't notice because the flame wouldn't go out either. hopes this helps :)
Pretty much, the heat makes the air in the beaker/flask expand and then when the flame goes out the air in the beaker contracts and pulls the water inside.
i think the air density became much less in side the flask so the outside air density tryed to force its way in by pushing on the water, is this what happened
easy explenation is fire req 3 components a heat sorce a fuel sorce and air. by cutting of his flow of air, the fire will consume all air inside, there by creating a vacuum, in a attempt to retake air into the bottle it will suck up the water as it covers his only way to take in air,
LOL try doing that with a capillary tube and a bunsen burner... I had an experiment once where if we turned off the heat before we took the tube out of the water the water would shoot up that tube and shatter it due to the heat.
the fire sucked the air out of the bottle and no air could come from the opening of the bottle so it had to fill itself with water which was by the opening, i think that's kinda what happened (haven't had that at school yet but that sounds most logic to me)
no the fire expanded the air in the bottle which made the air escape then the air in the bottle contracted creating a vacuum which pulled the water in the bottle
u light a candle and put it on a plate which has water on it u put the lighted candle in the middle and u put a cup i prefer a see threw glass and the the water should go in the glass!!
p.s. my sister did this for her 5th grade science fair!! it was cool
u know wat....unfortunetly it didn't work out for me as how it did with u......i mean like with me just as the water reachs the candle its stops pouring n. it doesn't get filled till the top or something like that
can somone plzee tell me from where to get the information about the explaination of dis science experiment, cuze i have marked dis as my project, and we have to explain our projects, and i have no idea about y iz it happening.......
Dame, thanx alot man, i'm really thanful, u don't know much dis means to me,
and i hope u get everything u wish for in ur life xP(only f it iz good, so i don't get blamed for it then xD)....god bless u>
but u know wat.....today was the day that i should submit the project and it was ............a SUCCESS................along with the explaination, well anyhow i really appreciate that u bothered to write that comment, i really am thankful =)
It's because flames use oxygen to allow it to burn. When you cover it, the flame uses up all of the oxygen and when there is no more oxygen, the flame goes out. Because of the oxygen getting used up, there is built up pressure. There is more pressure outside of the beaker than inside because the air has been depleted from the candle in the beaker. The area of low pressure which is the beaker then sucks up the water. The water goes to the area of low pressure always.
Partially correct. The air is being excited by the heat of the flame, and expands creating high pressure in the flask. Notice bubbles at beginning of video at base of flask before flame expires. As the oxygen is depleted, the flame goes out...as does the heat. Slowly the air that is remaining in the flask returns to the ambient temperature outside the flask, but has less air than before in the same container...creating low pressure, or vacuum. That is what pulls the water into the flask.
Not entirely true. The heat of the flame excites the air in the flask, increasing its volume. That air, being restricted by the walls of the flask, spills out of bottom. Bubbles. As the oxygen is changed to CO2, the flame/heat goes out. As the flask's air returns to ambient temperature a vacuum is created due to cooling of gases (contraction). This begins pulling on the walls of flask, and ultimately the water is drawn up the neck of flask. Kinda like sucking on a straw.
Fire needs air , the air from in the bottle is used up by the candles , then the candles go out , because there is no air left in the bottle , there's a sort of vacuum inside, sucking all the water up.
NOT THAT COOL. there is a perfect scientific explaination. Fire needs oxygen heat and fuel t burn on. When you put the jar over the candle, it stops the oxygen. The candle uses up all the oxygen thats left and it gos out. SIMPLE AS 123!!
I can't believe two years later people are still saying that the flame is making the oxygen in the flask disappear, creating a vacuum. Things don't just "disappear", not in this universe anyway. The flame is merely converting the oxygen into carbon dioxide. Simply converting one gas to another doesn't create a vacuum.
The experiment proves that warm air is thinner than cold air. Just read the second comment (by fizdup), he's got it right.
This comment has received too many negative votesshow
lol oxygen does get burnt which causes a vacum
and the flame would create the amount of oxygen it uses which causes a vacum and the oxgen being burnt and used up can clearly be seen as the flame goes out and the water trys to replace the oxygen.
You're wrong. Even though the oxygen is being used up, it's being replaced by carbon dioxide so there is still pressure in the flask. As I said, converting from one gas to another doesn't cause a vacuum.
What's really happening is the flame heats the air, cuasing it to expand. The thinner air pushes its way out of of the flask (you see the bubbles shortly the guy puts the flask on over the candle). When the air cools again, it contracts, pulling the water in.
ummm wow u guys r mental retards... its so easy to explain and u just start talking some bull shit about sound needing to travel through air. this guy is practically a moron. what happens is the flame burns all the air and oxygen in the container, so there's a vacuum. and the water goes into the vaccum.
OMG. Teacher is telling that light doens't need matter to travel and that ether was just a silly thing. Well teacher, please explain how light travels when there is no matter. Light is a wave and waves need matter.
TheVunz123, light does not need matter, or conductor, to travel. Remember there is no air in the outer space beyond our planet earth, yet the light still traveled through the outer space and came to our planet from the sun. Light energy has both wave AND particle characteristics (quantum theory), whereas sound only displays wave characteristic.
Light has particle characteristics only when observed (Kopenhagen interpretation of quantum physics). Check out Ether physics for 'new school' science.
Just search it up on internet Thevunz123. Information on characteristic of Light is everywhere. Or just just look up something called "photon". As an old school science student i am, i wouldn't check that thing you mentioned, sorry. :(
Nonetheless, light does travel without the presence of matter.
This is clearly a class in some school probably middle or highschool, thus he is teaching basics. Why are you trying to come off as intelligent on youtube, it is really not that serious.
That's incorrect. It's true that oxygen is used in combustion, but CO2 is formed--which is itself a gas. Indeed, cool O2 is turned into HOT CO2--which itself is part of the heating.
The gas (air) is lost from the container by being heated and expanded (you can see it bubble out in the first second or two). When the remaining air inside cools down, the pressure becomes lower than atmospheric pressure, and water is thus pushed into the container.
"contraction of molecules" is not a good phrase. The behavior of a gas follows the gas equation, where pressure is proportional to volume and temperature.
In this case, with the top open, higher temperature increases the volume--and air molecules escape. When the temperature deceases (but the volume stays the same, because the top is now blocked), then pressure is reduced. The pressure differential causes the greater pressure to push the water up into the bottle.
I don't think it is exactly capillarity, Residentevillord. When the fire goes out due to lack of oxygen, there is a tremendous decrease in pressure inside the container. So just like in cyclone,(where air flows from high pressure surroundings to low pressure interior), water from the trough flows into the low pressure container.
Don't need the mythbusters for this one. The air is really hot while the flame is still there, but when it goes out, the air cools down. This makes it contract, and something has to occupy the space no longer being used by the air. The only thing able to get inside the bottle is water because of how it is sittig.
It is very simple. You just light a candle, place it in a trough of water and invert a glass container bigger than the candle (preferably with a tiny hole submerged in the water.). You will see the effect - there is no prearrangement. You just do what you see in the video.
have you ever swollowed the air in something such as a bottle until there's little air in it and it kind of suctions to your tongue. same principle here, the candle eats all the air in the glass bottle (fire needs air to stay alive) so that there is little to no air in the bottle, then just like a suction cup the water fills up the glass bottle... it takes so long because there is little space between the bottom of the glass thing and the bottom of the tin pan
Thats actually not what happens. What happens is the air inside the bottle is heated up by the flame which makes it expand and some of it leave the bottle (higher temperature gives lower density). You can see this from the bubbles when the bottle is placed in the water. Then as the flame is killed, the temperature goes down again and the density goes up. This is the opposite of the expansion. You now have lower pressure inside the bottle than outside which sucks the water inside.
ave you ever swollowed the air in something such as a bottle until there's little air in it and it kind of suctions to your tongue. same principle here, the candle eats all the air in the glass bottle (fire needs air to stay alive) so that there is little to no air in the bottle, then just like a suction cup the water fills up the glass bottle... it takes so long because there is little space between the bottom of the glass thing and the bottom of the tin pan
ok king cole is right. The fire dose not heat anything up it uses up the oxygen and creates a vaccume and that vaccume suck the water up into the "beaker" "flask" thing what ever you want to call it.
the earth has no gravatational pull, it comes from within us all, we all have our on gravity field that surrounds us, it binds us all together like metachlorines, i have 5281 of them, how many do you have?
At the risk of getting 'thumbed down', I reckon there's two things going on here. Initially, the water is rising as the oxygen is being used for combustion. It appears, though, that the water continues to rise well after the flame is extinguished. I reckon that this is due to the remaining gas cooling and decreasing in pressure. This causes the air outside (which has stayed at roughly the same pressure) to push the water up that little bit more. Any thoughts?
It's just because of the heat: the space between the atoms is growing! But you see that the flame goes out and the air cools down: The space between the atoms becomes smaller and there must be something for in the place of the remained space: Water
holy crap people, did any one learn anything in science class? This has nothing to do with oxygen feeding a fire! You can do the same thing by taking a flask (beaker) that has been heated in an oven, stick it on, and wait, it sucks up the water. Use warm water or it will break the flask! What IS happening is the air in the flask is being heated by the candle, or any other source, when the fire goes out, that hot air cools, and contracts (shrinks) and sucks in whatever it can to replace it!
you guys are missing the point a bit here, so the oxygen is being used up by the candle right?
but that oxygen is being converted into CO2 and H2O. because the candles molecular formula is C25H52. but the CO2 and the H2O add up to 51 moles being produced by one mole of candle wax and 38 moles of oxygen. so by avogadros theory the volume shouldnt decrease. by all accounts it should probably increase. thats why its so confusing.
i think this is basic princple s about pascals pressure and atmospheric preaassure and density

simple...fire takes oxygen...so the water gets sucked in by pressure
Morfh158 3 years ago
not only does it take oxygen to burn but C20 drowns it out as well since it has no place to go

That's incorrect. It's true that oxygen is used in combustion, but CO2 is formed--which is itself a gas. Indeed, cool O2 is turned into HOT CO2--which itself is part of the heating.
The gas (air) is lost from the container by being heated and expanded (you can see it bubble out in the first second or two). When the remaining air inside cools down, the pressure becomes lower than atmospheric pressure, and water is thus pushed into the container.

So basically the cooling air in the container causes a contraction of molecules which is lowered air pressure?
SevereTstormFan 3 years ago
"contraction of molecules" is not a good phrase. The behavior of a gas follows the gas equation, where pressure is proportional to volume and temperature.
In this case, with the top open, higher temperature increases the volume--and air molecules escape. When the temperature deceases (but the volume stays the same, because the top is now blocked), then pressure is reduced. The pressure differential causes the greater pressure to push the water up into the bottle.

I don't think it is exactly capillarity, Residentevillord. When the fire goes out due to lack of oxygen, there is a tremendous decrease in pressure inside the container. So just like in cyclone,(where air flows from high pressure surroundings to low pressure interior), water from the trough flows into the low pressure container.

Don't need the mythbusters for this one. The air is really hot while the flame is still there, but when it goes out, the air cools down. This makes it contract, and something has to occupy the space no longer being used by the air. The only thing able to get inside the bottle is water because of how it is sittig.

It is very simple. You just light a candle, place it in a trough of water and invert a glass container bigger than the candle (preferably with a tiny hole submerged in the water.). You will see the effect - there is no prearrangement. You just do what you see in the video.

have you ever swollowed the air in something such as a bottle until there's little air in it and it kind of suctions to your tongue. same principle here, the candle eats all the air in the glass bottle (fire needs air to stay alive) so that there is little to no air in the bottle, then just like a suction cup the water fills up the glass bottle... it takes so long because there is little space between the bottom of the glass thing and the bottom of the tin pan

Thanks i get it now! =]
xxxglamourbabexx 3 years ago
Thats actually not what happens. What happens is the air inside the bottle is heated up by the flame which makes it expand and some of it leave the bottle (higher temperature gives lower density). You can see this from the bubbles when the bottle is placed in the water. Then as the flame is killed, the temperature goes down again and the density goes up. This is the opposite of the expansion. You now have lower pressure inside the bottle than outside which sucks the water inside.

ok king cole is right. The fire dose not heat anything up it uses up the oxygen and creates a vaccume and that vaccume suck the water up into the "beaker" "flask" thing what ever you want to call it.

the earth has no gravatational pull, it comes from within us all, we all have our on gravity field that surrounds us, it binds us all together like metachlorines, i have 5281 of them, how many do you have?

At the risk of getting 'thumbed down', I reckon there's two things going on here. Initially, the water is rising as the oxygen is being used for combustion. It appears, though, that the water continues to rise well after the flame is extinguished. I reckon that this is due to the remaining gas cooling and decreasing in pressure. This causes the air outside (which has stayed at roughly the same pressure) to push the water up that little bit more. Any thoughts?

AweSomo84 3 years ago
not that cool, the fire burns out the oxygen, removing matter from the jar, then something needs to occupy it, thus the water rises
xsnowboarder93x 3 years ago
It's just because of the heat: the space between the atoms is growing! But you see that the flame goes out and the air cools down: The space between the atoms becomes smaller and there must be something for in the place of the remained space: Water

holy crap people, did any one learn anything in science class? This has nothing to do with oxygen feeding a fire! You can do the same thing by taking a flask (beaker) that has been heated in an oven, stick it on, and wait, it sucks up the water. Use warm water or it will break the flask! What IS happening is the air in the flask is being heated by the candle, or any other source, when the fire goes out, that hot air cools, and contracts (shrinks) and sucks in whatever it can to replace it!

you guys are missing the point a bit here, so the oxygen is being used up by the candle right?
but that oxygen is being converted into CO2 and H2O. because the candles molecular formula is C25H52. but the CO2 and the H2O add up to 51 moles being produced by one mole of candle wax and 38 moles of oxygen. so by avogadros theory the volume shouldnt decrease. by all accounts it should probably increase. thats why its so confusing.
