See how people are coping with the scary chill of the polar vortex

See how people are coping with the scary chill of the polar vortexParts of the Midwest are experiencing the coldest temperatures in 20 years this week as the polar vortex takes hold.  On Wednesday morning, it was -22 degrees in Chicago, with a wind chill of -49, according to CNN. In northern Minnesota, wind chills dropped to -65. Flights are being delayed and cancelled. The USPS has partially halted service. In some places, it's possible to get frostbite after only a few minutes of skin exposure. On Twitter, people are sharing the polar vortex's wild effects in their own hometowns. There's indoor ice, boiling water vaporizing into the air, innovative winter-wear layering techniques, and (crucially) bundled-up dogs. > Has not moved since being dressed to go out.

If you need to go outside to do the boiling water challenge, fine, but head back inside ASAP. And bring your pets with you! ## WATCH: The 18th annual No Pants Subway Ride streaks across the globe
