You’ve heard of a white Christmas, but probably never of a blue Christmas. Yes, BLUE SNOW fell on the city of St. Petersburg, Russia, on Dec. 26. Totally strange, unprobable! The freaky weather phenomenon sparked widespread fears that the snow was tainted with some kind of toxic pollutant. Now under investigation, officials weren’t able to offer an explanation for the blue snow yet.
The predominant theory among residents seems to be that the blue snow was caused in some way by the recent demolition of the city’s chemical-pharmaceutical research institute. Scientists have suggested that the tinted ice could be caused by cobalt, a metallic element, or methylene blue, a substance used in some medical treatments.
Residents were simply forced to attempt to go about their daily lives in spite of their shocking surroundings; shoveling the blue stuff, clearing roads and driveways.
Interestingly, this isn’t the first time that blue snow has fallen on a Russian city. Back in 2015, blue snow also occurred in the Russian city of Chelyabinsk, some 1,500 miles to the east of St Petersburg. The cause of that incident was determined to be blue food coloring used in Easter eggs, which had gotten into the ventilation system of a factory and been spread all over the area.
Moreover, the Siberian city of Omsk has twice experienced black snow. Pollution from a local power plant was determined to be the cause of the first encounter. Then there was an August “snow” when aluminosilicate was released from a local oil refinery.
Needless to say, residents of St. Petersburg should probably avoid getting into any snowball fights or creating any blue snow angels until the cause of the weird event has been determined to be non-toxic.
