(BEIJING, April 12) -- Wearing Beijing 2008 t-shirts, and with cleaning rags in hand, a group of 80 youth volunteers arrived Saturday morning at the National Aquatics Center (or "Water Cube") to perform a special service: They were on a mission to make the spectator seats like new again.

The volunteers worked hard for two-and-a-half hours to clean the Water Cube, demonstrating a high degree of Olympic spirit.
