The extreme cold has hit northern Sweden. Around Kiruna, the temperature dropped to below -40 degrees on Tuesday.
SVT Sápmi’s photographer Stefan Karlsson went up on the roof to try to capture how cold it really is.
He had a thermos of boiling water with him. He threw the water up into the air – and it flew like ice straight into his face. It is the result of very cold weather and the so-called Mpemba effect.
