Acropolis's caryatid beauties get laser scrub

The caryatid statues, which until the late '70s propped up a section of the Erechtheion temple on the Acropolis in Athens, are being meticulously cleansed of grime inside the Acropolis Museum. Conservators zap away dirt from the marble maidens with custom-designed lasers, as tourists watch the operation on monitors.
