Pandas + snow = endless amusement.

Its hard to say whether the pandas or the people watching have more fun. Video released Sunday by the Smithsonians National Zoo show adult giant pandas Mei Xiang and Tian Tian going all out on the roly-poly snow-day activities, sliding, somersaulting and starfishing in the frosting that caked their Washington, D.C. home.

Most parts of the city saw 2-3 inches of snowfall Sunday, the first significant snowfall in two years.

Mei Xiang and Tian Tians 5-month-old cub, Xiao Qi Ji, also ventured out into the winter wonderland for the first time but didnt stay out for long, according to NBC Washington . When the cub reaches age 4, hell be sent to China to become part of the breeding population there.
