Footage of a bubble turning into an icy sphere as temperatures drop to -35C in Canada.
In the video, filmed in Regina, Saskatchewan, on December 28, a bubble appears to freeze into a solid sphere.
Writes the filmer: “Frigid air does not mean you have to stay in. Bundle up, get out and create something amazing!”
Temperatures across Canada and northern US have plunged since Christmas.
