In case you haven’t noticed, it is as cold in Canada (and soon some parts of the USA) as it gets at the South Pole at times:

Woke up to a balmy -41C (-41.8°F) this morning in South Porcupine, ON. Thought I’d share what happens when you mix boiling water and a water gun and take it outside for a few shots.

It’s not just Northern Ontario that’s cold. Take a look at what’s happening in Toronto harbour.
I liked this because it simply explains the Mpemba and how it came about:
http://chemistry.about.com/od/waterchemistry/a/Can-Hot-Water-Freeze-Faster-Than-Cold-Water.htm
“There is no definitive explanation for why hot water may freeze faster than cold water. Different mechanisms come into play, depending on the conditions. The main factors appear to be:
Evaporation, Supercooling, Convection, Dissolved Gases, Effect of the Surroundings”
The best diet is the Calorie per Gram diet.
Most people will feel satisfied eating 1500 to 2000 grams of food per day and most people burn 2000 to 3300 calories per day depending on your weight/size and to a much much smaller extent, your activity level.
If you restrict yourself to foods that are close to 1.0 calorie / 1.0 gram, you can eat enough food to feel satisfied and you will lose weight.
The good news is that there are lots of food that taste good that are close to 1.0 calorie/gram. You can eat a varied diet. Bad news is that there are some foods that you just have give up.
Example, Calories/gram –> Pasta –> 3.5 —> Big, big Fail, now add Alfredo sauce and its 5.0
Rice —> 3.0 —> Fail
Diet oatmeal —> 4.0 –> Big Fail and False Advertising
Bowl of Soup –> 0.4 —> Big Pass
Ham —> 1.0 —> Pass
Turkey Breast — 0.9 –>
Potatoes (omg, Carbs) —> 0.8 –> Pass.
Basic math answers lots of questions. Anything under 1.5 calories/gram will work.
Bill, that is cool! I would guess it would even out cholesterol as well. Which would give the old gall bladder a break. Gall stones are nasty painful things made from cholesterol.
Bill Illis,
Looks like the soup and potatoes at least may be low in calories/gram because of water content.
Reminds me of what a Science teacher told us way back in Junior High. A good way to control calorie intake is to drink a big glass of water before eating. Makes you feel full for 15-30 minutes. Seems it could work if you can avoid eating between meals.
Of course, if you can avoid eating between meals…
Thinking about this the past week; timed lock on the fridge door! Next, the cupboards, the kitchen …
I did comment once before:

about the ‘Mpemba Effect’ .
In this video it looks to me like the ‘hot’ water is sublimating-? at a rapid pace ,it doesn’t look like it is depositing on the railing.It is/is it instantly sublimating/deposting ice/vapor to the air…?and then evaporating?or or is the ice falling out of the air?It would be nice to have absolute/relative humidity of the air?.It looks pretty dry in that video, but in my area it is offically28°F clear 74% RH. Long story short ,that led me to…..the heat of sublimation which is also an interesting topic.
and after all that, today seeing a video reference to that effect.with further experimentation withe hotter/cooler water done by others i’m sure(not those temps where i’m at)and awaiting the results of.
My opinion now is that hotter/cooler water will also freeze and any water that is above freezing will also freeze faster than…of course frozen water.
Thanks for the interesting info

“Here is an interesting experiment to freeze water.”
~ ~ ~ ~
The world needs more STEM (science, technology, engineering, and mathematics) classes. In this case Chemistry.
I’ve seen this trick (the operative word) done by chemistry instructors and with colors and song. For example, when the words of a school’s fight-song get to, say crimson, the mixture in the beaker changes color to – crimson. That takes just the right mix of chemicals and very good timing. The change from liquid to solid can be used in the same way to stunning effect.
I thought the video was going to show rapid crystallization of very still super-cooled water with a small tap on the side of a pan. I’ve done this. It is supposed to work with sugar solutions also but I haven’t personally done it.

Not an explanation but just a wild guess.
If the water (and the room?) were near or below freezing then perhaps the sudden drop in pressure resulting in the freeze?
My fabulous boyfriend grows lots and lots of potatoes. And did I mention he is fabulous???
Fun video.
Is that dirty, black, sooty CO2? ……….Or have I seen too many MSM photos of coal-fired power stations?
(sarc)
I am just getting the hang of the AGW language. Hotter temps=Antho (man made) Global Warming. Masses of ice=AGW. Cold temperatures=AGW. Long spells of cold weather=AGW. If you are ice bound on a boat in the Antarctica=AGW. This all adds up to one thing, AGW. Yeah, right!!!
There is a coal electricity plant near the freeway on my way to and from work. If I did not understand how the sun can change the color of steam from white to dark, I would be convinced that this plant gives off sooty stuff depending on the time of day. But of course it does not. Steam is steam, even in the shadows.
======================================================================

What it adds up to is that Man can’t control nature but some men are using nature to try to control Man. (And make a few bucks in the process.)

71 new papers reported in 2013 telling us the sun is driving our climate not Co2: http://hockeyschtick.blogspot.com/2014/01/71-new-papers-reported-in-2013.html#
Wonder how that AGW scare mongering is working for the warmista’s when we have snow owls in California, wattsupwiththat?: http://www.miamiherald.com/2014/01/03/3850232/snowy-owl-invasion-of-us-extends.html#

Village Idiot sorry but the ‘weather’s not climate’ argument is a dead duck , given the numbers of times any extreme weather event has been jumped on as ‘proof’ of AGW .
I fact I will give you 100-1 the first extreme weather event of 2014, no matter what , will follow this pattern.”
Yep, 100% right there knr! 5 days into the year and the first weather extreme hits the headlines and Voice of Russia report:
“Dr Keiran Hickey, a climatologist at the National University of Ireland in Galway, said: “The big issue here is the number of weather extremes we’re seeing around the world, including in the UK and in Europe but also obviously in North America as well, and the and that would fit nicely into the predictions for climate change and global warming in that we would see moseverity of these big weather events seems to be getting worsere climate disturbance, less so-called ‘normal’ weather and more extremes taking place.” ”

Of course, regular truther ‘Justtthefactts’ proves that 2013 was the dead duck reference ‘Weather Weirding’:

No unusual weather on the horizon in 2014 then….
Yes, hot water freezes faster than cold water. I’m Canadian and we were shown this very early on in school. Demonstrated! Because no one would believe it at that age. Another counter-intuitive fact is that it tends to get warmer after there is snow on the ground compared to before. Not all the time, but enough that it’s a well known fact where it snows a lot or where it gets cold for a long time before it snows.
Actually it’s beautifully visible if you switch the video to 1080p that the railing got wet from the perfectly liquid stream of hot water that puts out a lot of steam which then turns into fine microcrystal powder which continues further with the movement of the air. No instant snow here. Same with other videos of this effect … it’s just freaking steam. http://www.youtube.com/watch?v=_6_lJYj4GX4 .. beautifully visible heavy blobs of water that drop down. The hot water = faster ice does not play a role here. Just that on a cold day the steam forms a thicker formation and people go “oh my gosh look at that.. instant snow….. no.. no instant snow.. just thick steam.
For the water to completely turn into ice you would have to shoot it with a much higher velocity and in more sprayish formation – just like the snow cannons do.. and they don’t need to pump hot water into those cannons.
Jeez.. how many people actually take a moment to think and then visually inspect the video?
There is more to this recent and consistent cold weather than just the current jet stream changes. Northern hemisphere winter temperatures have been declining for 15 years so there is a much longer climate trend caused by perhaps the cooling Arctic and Northern Hemisphere SST decline. . Both North Atlantic and North Pacific SST’s are cooling slowly although the North Pacific cooling started more after 2005 . A negative PDO since 2007 means there is more colder water along the eastern Pacific than in the western and central Pacific .These factors all add to the net cooling .
AO was record positive [around 4] during December and was positive all of December yet we were already getting colder temperatures as we see for Winnipeg, CANADA. and other parts of Canada. in December. So despite POSITIVE AO , cooler temperatures were setting in.

We used to dump left over liquid nitrogen from hand-held dewars on the ground outside. So much vapor came from the process, that it looked like there was a fire. Used to drive our hazardous materials team crazy — they asked how we disposed of excess liquid nitrogen (we let it go back into the air it was taken from). BTW, liquid nitrogen does a great job on killing ants.
I am so glad we moved to the tropics. The only temperatures below freezing are in our freezer, and occasionally transferred to a glass of Scotch on a temporary basis.
Pool currently at 32C….
If the oceans are cooler, though still anomalously warm, land temps would also set up as cooler. Meaning that while the AO is positive in terms of anomalous pressure, land temps can be ramping down, simply because the ocean source of the heat has lessened. There is a slope to the process of oscillation changeover. Certainly when the AO is in negative pressure territory, loopy Rossby waves will bring polar-cold temps into more southern latitudes.
