The polar vortex has North America in an arctic grip, with temperatures plummeting to near minus 50, but a new trend has started dubbed the "Polar Vortex Challenge".<br /><br />The challenge features people throwing boiling water into the air so that the contents turn to mist instantaneously.<br /><br />But one Canadian has taken the challenge to another level after his attempt bypassed mist and converted into straight snow.<br /><br />The video shows a man filling up a mug with boiling water from a kettle and then throwing the contents at a wall, leaving a snow residue on the bricks.<br /><br />Kevin Parry, the person in the video, said: "I was surprised to find that boiling water immediately turned to thick snow - and not a mist - when thrown against a wall in the frigid cold."<br /><br />The video was captured yesterday (January 31).
