Usually, when you play ice hockey you play it on the side of the ice where the air is. Not these divers. They decided to take a puck and a pair of hockey sticks underwater in a frozen lake and do a bit of knocking around on the wrong side of the ice.
These two performed this stunt near Temirtau village in Siberian Russia's Kemerovo region. It's a neat idea, but we're getting cold just looking at them.
