Just how cold is it? Cold enough to freeze antifreeze!

SAINT CLOUD, Minn. – We keep talking about how cold it is across the U.S.

Now one photojournalist set out to determine, just how cold is it?

Apparently in Saint Cloud, Minnesota, it’s cold enough for antifreeze to become frozen.

The antifreeze, the kind you put in your car, is supposed to withstand temperatures as cold as 20 below.

But this time-lapse video shows even antifreeze isn’t invincible.

In about half an hour it froze into a slushy toxic mess.
