South Korean children smile with tumblers during a year-end campaign to raise funds for the poor in Seoul on December 15, 2009. The event was co-sponsored by the Korea branch of the global charity group World Vision and businessmen which sell the tumblers called 'Heartea (heart and tea)' mounted with a heat sensor for 25,000 won (21.5 USD).
