Lock lips to light Kissmas tree

The world's most interactive and intimate Christmas tree is set to get visitors to London's Covent Garden kissing this Christmas. The innovative installation, dark for most of the time, only lights up when 2 people kiss under the tree, local media reported. No kisses beneath the tree are likely to go unnoticed, with 50,000 lights illuminating Covent Garden's Piazza the moment lips touch. (See photo)
