A dental alginate mould of the kiss of a couple is displayed at The Science Museum's Dana Centre in London, Thursday, Feb. 12, 2009. Couples were invited to the kissing experiment, where as many styles of kissing were collected in moulds, and the moulds transformed into glass sculptures. (AP Photo/Kirsty Wigglesworth)
