Scientifically known as the Mpemba effect, named after Erasto Mpemba, this phenomenon is when warmer water – in this case tea – freezes faster than colder water in sub-zero temperatures. Photographer Michael Davies from Ontario, Canada captured the amazing images you see above just 20km south of the Arctic Circle by tossing hot tea in -40°C weather. Continue reading for three videos of this phenomenon and more information.
New Scientist recommends starting the experiment with containers at 35° C and 5 °C (95° F and 41 ° F) to maximize the effect. In a related study, it was found that freezer temperature also affects the probability of observing the Mpemba phenomena as well as container temperature.
