Hurdler twists bottles for environment

Star hurdler Liu Xiang's popularity and influence among sports fans earned him another special role on Monday in Shenzhen as he joined in an environment protection campaign as an ambassador.

The "I Twist for Green" campaign was launched by Coca-Cola's drinking water brand, ICE Dew, which features eco-friendly, lightweight bottles for consumers.

The bottles are specially designed so they can be easily twisted and compressed after consumption, thereby saving more than 70 percent of the space needed while the bottle makes its way to recycling.
