It's not just cold out there. It's insanely cold.

It's so cold you can turn boiling water into snow in the time it takes to read this sentence.

Eric Holthaus is a meteorologist who took a pot of boiling water outside in Viroqua, Wisconsin when it was -21 degrees, with a wind chill so severe that it felt like 51-below.

Watch what happens when Holthaus tosses the water into the air. It's instant snow and proof that Mother Nature is one cold woman.
