This is some Game of Thrones Long Winter shit right here. WBEZ Chicago posted this on their Facebook page last night:

We tested how quickly bubbles would freeze today. By the time this one hit the ground it actually started rolling.

Let's just repeat that so you understand how real shit actually got. Because of the polar vortex, in Chicago — where temperatures are a balmy -10°F this morning — bubbles freeze and start rolling. And I was complaining that it was 20°F in Texas today. Sorry, y'all.
