A polar bear sucks a popsicle with satisfaction at Tianjin Polar Aquarium in Tianjin, North China, July 20, 2011. The huge popsicles are specially made with fruits and vegetables frozen inside to help the center's pair of polar bears reduce their body temperatures. It's also meant to make bears get more active and have some fun while searching for the edible treats. [Photo/CFP]
