Watch this UNICEF video about actress Sara Jessica Parker's work to promote clean water programs on HowStuffWorks. New York's Tap Project asks New York diners to pay $1 for tap water to benefit UNICEF's water and sanitation projects. Parker, who is a lifelong member of UNICEF, says each dollar collected will provide clean water for 40 children. See how UNICEF's Tap Project works in this video from UNICEF.
