So, even if the Mpemba effect is real, you don't need it to explain how you make snow with boiling water in super-cold air. This video went viral worldwide, a few years. Here is a great video that goes over these points. you will see boiling water thrown from a cup, in the air, and freezing immediately, coming down as ice crystals. In the end, it's really difficult to create a theoretical model that has boiling water freezing faster than room water. Here's a quick compilation of viewer-submitted clips showing just how cold it is by throwing boiling water into freezing air. On top of that, the change in energy needed to go from a liquid to a solid is very large compared to the energy change for cooling off a liquid. In the video posted earlier this week, Freiheit runs outside in a T-shirt and jeans with a kitchen pot and then hurls the boiled water in the air. There can be different thermal interactions with the environment for a hot or cold container of water. You have to consider evaporation and convection currents. So many small factors can have a significant impact on the cooling process. However, it is really hard to get nice data for hot water going all the way to frozen water (also known as ice). This effect is often referred to as the Mpemba effect and it has been observed for quite some time- even Aristotle considered this phenomena.

The scientific trick was also possible in Wisconsin on Tuesday, with one instructor turning it into a teachable moment.Īndy Reiche of the Wausau School District conducted the science experiment on video showing a cup of boiling water thrown into the minus-5-degree air - and immediately turning to snow.But what about another, related question: Is it true that boiling water freezes faster than room-temperature water? Does this have anything to do with the boiling-water-to-snow stunt? Not really. (Source: Viva Frei/YouTube) After a series of mesmerising photos and videos of freezing bubbles went viral online, the latest scientific experiment to take the Internet by storm is the Mpemba Effect, which is basically just throwing hot water into the air amid freezing temperature and watch those droplets transform into a snow cloud mid-air. “#Chicago is so cold right now that hot water turns straight to snow,” tweeted Eylon Levy, along with a video showing him throwing a mug of water over a balcony and the liquid flaking out.

It was minus 23 degrees Fahrenheit at Chicago’s O’Hare International Airport on Wednesday, the coldest since that date in 1966, when the temperature recorded at the travel hub was minus 15 degrees. Experiments have been done that looked at the convection currents. A daughter burst into laughter as her father surprised himself with a faceful of snow and fell over while attempting a science experiment in freezing temp. Experiments on the Mpemba effect have often reported a hot top 5,8,10, as we would expect. Beautiful video shows man create a cascade of ice by throwing hot water into the freezing cold air This is the amazing moment a man throws boiling water into the freezing cold air, which then. Ice-pectacular Amazing moment hot water immediately FREEZES after being thrown out into the air on a -44C day.
“Throwing a cup of boiling water in the air, when it’s minus 27 degrees (Celsius),” journalist Adam Roberts tweeted Wednesday along with a mesmerizing video taken in Chicago. The latest video craze that seems to have spread as fast as the winter winds shows people throwing water into the frigid air, causing it to immediately turn into snow.
Incredible videos posted on social media show folks in frigid parts of the country dumping a cup of water outside, and the liquid instantly turning into a cloud of flakes. Videos emerged on social media show people throwing hot water into the freezing air and watching it turn into ice crystals instantly amid temperatures of -43. It’s so cold in the Midwest, boiling water is turning into snow.

The water is not 'freezing in mid air' as these videos so often describe.
People often describe this as being so cold that boiling water freezes instantly. This experiment was conducted with an outside temperature of -8 degrees and a dew point of -19 degrees.
