Years ago, I was in Alaska for a few months, and before that, in Wisconsin back in the late 1960s and early 1970s. Here's an image from radio station KNOM's Nome Static March, 2006 newsletter.



KNOM volunteer Eric Gauthier tosses hot water in the air.

It freezes instantly into vapor and pellets
when the air temperature is 30 below, Fahrenheit.
If it's 50 below or colder, it explodes
with a 'poof' entirely into frozen vapor.
