Russia’s ‘Dubak’ challenge creates icy works of art

A new trend has made its rounds on Russian social media in recent weeks called “The Dubak Challenge,” (from the Russian дубак, a slang word for intense cold) in which boiling hot water is thrown into sub-zero air for a beautiful sight. The result comes from the Mpemba effect, in which hot water freezes faster than cold water.

Warning: While the effects are tempting, the process is a risky one. We strongly advise you to not try this at home.
