What do you mean by cold pants?

Recently, influenced by the "polar vortex", people have fun in the cold. Some netizens deliberately frozen jeans and put them in various interesting scenes as part of the "cold pants" challenge. A netizen in Minnesota said, "What else can you do in such a cold day?"

According to Fox News Channel's February 1 Sunday report, the behavior of freezing pants and then "standing" on the front lawn has recently become popular because of the polar vortex temperature in the United States.

Tom Grotin, who claimed to have thought of this idea, told reporters that the temperature outside needs to be below 0 degrees Fahrenheit (MINUS 17.8 degrees Celsius) before pants can "stand up".

According to the Des Moines Chronicle, as long as the temperature meets the requirements, anyone can soak jeans in water and leave them outdoors to wait for the pants to take shape.

According to the report, this challenge is not limited to jeans. On Instagram, you can see people freezing pajamas, ice hockey suits, karate suits and even police uniforms.

Grotin said: "Life has not completely stopped, but the pace of life is a little slower.
