Actually! This was a very clever setup by a team of divers in the Arctic, I believe. The person is upside down, their bouyancy belt calibrated just so that they are slightly lighter than water, and able to walk upside down on the ice. In the first segment, when his mask vents, watch the bubbles flow DOWNWARD, which is really the up that we know. Science is really fricking cool!
