The U.S. National Zoo's Bao Bao experienced her first snowfall on Tuesday...<br/> <br />...as three to four inches -- or seven to ten centimeters -- of snow fell on the nation's capital.<br/> <br />The sixteen month-old Giant Panda cub spent most of the morning rolling around....even getting her mother in on the action.<br/> <br />Bao Bao is only the second panda in the zoo's history to live a full year.<br/> <br />The zoo says many offspring of this endangered species are unable to survive infancy.<br/> <br />Today, Bao Bao appears not only to be healthy -- but also having a blast.
