During this recent cold wave of the season, your social media was definitely filled with people playing with the "boiling water challenge". The viral phenomenon makes people go to the sub-zero outside with a pot of boiling water, it turns into a spark of ice mist.
While this may seem like a highly instigramic but harmless pleasure, doctors now warn that the experience can also help you get to the emergency room.
Seven people were treated for second degree burns and one person in a Chicago hospital following an unsuccessful attempt, according to an unsuccessful attempt, according to a source ABC 7 News. One of the patients might even need to undergo surgery to treat burns.
"We strongly warn people not to meet the challenge of boiling water," said Dr. Arthur Sanford, a burn surgeon at the Loyola University Medical Center in Chicago. Chicago Sun-Times.
"There is no sure way to do it."

"The whole gamut ranges from burning a hot liquid to exposure to cold air," added Dr. Jeff Schaider, president of Cook County's Emergency Medicine Department. Health, in Chicago, The time of the era. "If your hand has water on it, it freezes pretty quickly. It's a bigger risk, actually.
Look, if you are going to do it (at your own risk), be sure to throw water away from you and other people. Always remember that you are just drinking a pot of boiling water, so act accordingly.
Despite its dangers, the challenge is a nice little demonstration of the Mpemba effect, the observation that hot water can freeze faster than cold water. Discarding cold water in the air will not work because it will not freeze in time. However, boiling water will be hot because its temperature can drop much faster, turning it into a snow-like mist.

Remarkably, scientists do not have a clear explanation of this effect, although there are some theories. One idea is that the evaporation of hot water is faster, which reduces the volume left to freeze, while another suggests that different concentrations of dissolved gases, such as carbon dioxide , could affect the cooling rates. Similarly, one theory points out that hot water could cool down faster due to increased convection currents. One of the latest theories in this respect everything is connected with the covalent bonds that hold the water together.
Regardless of the mystery of Mpemba, remember to stay safe, my friends.
