You probably have an idea of what its like at zero degree celsius or just below. But do you know what it feels like when the temperatures drop to less than -20 degrees?
With temperatures dropping down to a steep -40 degree celsius, most parts of North America are now frozen, thanks to the Arctic polar vortex.

Reports also reveal that for the first time in history temperatures have dipped this low in the US.
