Ya, it's cold in Canada but that was freaking awesome.

Boiling water actually freezes faster than room temperature water. it's called the Mpemba effect.
http://en.wikipedia.org/wiki/Mpemba_effect
hvkzJan 19, 2011
According to the article, this can occur in very specific situations and inside some sort of container. The water in this video instantly freezes as its tossed into the air, in which case the Mpemba effect does not seem to apply.
donkeybonggggJan 19, 2011
it happens all the time when you separate water into smaller particles like throwing it near vaporization and type of container does not matter...go back to chemistryComment is buried, click here to see the rest.

No need to be a jerk, the guy read the article and said "doesn't seem to apply"
yarsrevenge2600Jan 19, 2011
Still really cool to see in action. Water hot enough to boil is still very, very hot and this is not something you would see normally even with room temperature water. It's very cold out there and this is a neat demonstration.
largentJan 19, 2011
You can see unfrozen water fall directly to the ground in the 3rd toss.
beckeristJan 19, 2011
The rate at which the temperature decreases is faster, not that it freezes faster. It's analogous to velocity vs. acceleration. Faster deceleration doesn't mean you will hit zero sooner if your starting temperatures are drastically different. For instance, if you put 100 degree (F) water and 35 degree water (F) (or roughly 38C and 2C respectively) in a freezer, the warmer water will decrease by MORE degrees in 10 minutes, but it won't freeze over first. The RATE of the warmer water will be "cooling faster" but that does not mean it will freeze first.
thex00Jan 20, 2011
Mate, _seriously_, read the wikipedia article. You've just proven that you didn't. The point of the Mpemba effect _is_ that water at a higher temperature may freeze before a colder one if placed simultaneously in a cold environment. However counterintuitive it is.
Closed AccountJan 20, 2011
Except under normal conditions (like the one shown here) the Mpemba effect does not apply.
In this case, the water freezes so fast becuase it is being thrown fast enough to really spread it around. Which is why she was still able to pour it into the glass without it freezing.

Ahh the Mpemba effect in action. That is really cool though and I'm gonna show off to some people next time it gets really cold here in CT.

I live in Alaska and yes it is fun to do that however aside from that and licking flag poles I and am ready for summer.

Alaska has a summer? You learn something new every day.

lol "thats so cool" im gonna try it!

The hot water is able to heat up the air surrounding it. Because hot air can contain a lot more of water vapor than cold air, it forces the hot water to sublime into vapor immediately. Of course this is for a short duration, it becomes mist in the same fashion as human breath on a cold day.
newmanium2001Jan 19, 2011
Uh, wait what? No.
This has nothing to do with hot water heating up the surrounding air and the Clausius Clapeyron equation (temperature vs. saturated vapor pressure). That is why you see your breath, but it is not why this hot water *deposits* (not sublimes) to ice.
The boiling water turns to ice because boiling water is very volatile and turns into very tiny droplets immediately. The small size and high temperature of these droplets causes them to turn into ice immediately. It's a factor of surface area and cooling, not saturated vapor pressure as you're describing.
makushimirianJan 19, 2011
"heating up the surrounding air and the Clausius Clapeyron equation (temperature vs. saturated vapor pressure). That is why you see your breath"
Interesting - could you explain this a little more? I'm familiar with the equation, but not how it relates to seeing your breath.
newmanium2001Jan 19, 2011
In a nutshell, there is an exponential relationship between the amount of moisture the air can hold vs. its temperature.
The air in your body is at 98.6 F and very moist. Breathing it out into 15 deg F air immediately "squeezes" the moisture out of your breath because as the air cools, the immediate volume of air near your mouth can't hold that much moisture. As your hot breath exits your mouth, it quickly expands and mixes with the ambient air, cooling it and spreading the moisture over a larger volume until its absorbed into the ambient air and you no longer see it.
Physics FTW!

Some who worked at Yellowstone told me that sometimes it get so cold in the winter that the water from Old Faithful freezes before it hits the ground.
philbertJan 19, 2011
I've seen other videos of people doing that, of course it only works in really cold areas.

You don't have to be in the north pole to do this...we did it all the time when I was younger and I live in minnesota

I guess it really depends on which map you look at...those who don't have canada on their maps consider us the north pole...I have yet to find santa though

"It's gonna vaporate!"
benwhatelyJan 19, 2011
That is awesome. I had heard of that happening before, but always thought that it was probably an exaggeration. It isn't. Wow.
wagedomainJan 19, 2011
Pretty sure the water is actually evaporating, not freezing. If it froze it would be a bunch of chunks of ice, instead it becomes a vapor mist.

I love the Australian accent of the woman holding the camera.

iboxJan 19, 2011
It's the latent heat of fusion. "at the transition point between solid and liquid (the melting point), extra energy is required (the heat of fusion). For freezing, the molecules of a substance arrange in an ordered state. " http://en.wikipedia.org/wiki/Latent_heat_of_fusion The hot water has more than enough energy to cross from water to liquid in the sub zero temperatures, throwing it up in the air allows the water to give up it's energy faster and freezing rapidly. this is the same concept in snow making used by ski areas.
arsinoeJan 19, 2011
If it was really freezing cold, she'd be wearing mittens and a hat. Just saying.

So, how cold does it have to be for an effect like this to happen? I mean, obviously it's not going to happen when it's like 30 degrees but what about when it gets down to the low teens or single digits?
Basically, is there a chance in hell of ever pulling this demonstration off during a freak cold snap here in the south?
xtomtomxJan 19, 2011

I live on the west coast of Canada; it's currently 4 ˚C and sunny. Sure, it's not Florida, but the winters here are pretty mild.
mazebotJan 19, 2011
great despite I know the physic behind it.
-can not stop my self posting a tad bit: its all about energy used to change from one state to the other - not about cooling then changing state.
gartasticJan 20, 2011
The same thing happens in Alaska, except this guy does it with a super soaker full of hot water http://freq.ly/f5u7nB
warpfieldJan 20, 2011
Just goes to show, when you increase the surface area of a liquid, it's temperature matches the surrounding ambient faster. Same reason why a large cup of coffee stays hotter than a small cup.
ophelloJan 20, 2011
Yeah...that tends to happen when you throw it into the air and it spreads out, letting the cold air zap its heat from all angles due to the massive increase in surface area.

Yes that is true boiling water freezes instantly and easily as compared to water at normal temperature, and here is the reason why, "Newton's Law of Cooling", it states that heat transfer between surface and surroundings is directly proportional to the difference in temperatures. As the temperature difference between a hot water and ambient temperature is more, the water freezes instantly.
