Scores of US pranksters were reportedly burned revelling in the novelty of record-breaking low temperatures.
At least 50 people were hurt as they tried to throw boiling water into the air and watch it freeze before it hit the ground, reported the Los Angeles Times.
The newspaper said it counted scores of people on social media trying the gimmick, as temperatures plunged to as low as -26 degrees.
A television reporter also demonstrated the trick live on air (from 1m10s).
