Scientists used a laser to layer evaporated gold onto a piece of film through a stencil reading "guinnessworldrecords.com." The message was attached to the knee of an insect much like the bee in this photo.
LONDON, Nov. 24 — As advertisements go, it's the bee's knees.To launch the Guinness Book of Records' new Web site, scientists created the world's smallest ad, slightly bigger than the diameter of a human hair, and mounted it on the knee of a bee."On a day-to-day basis, we handle the claims and evidence of the most amazing facts and feats," said Stewart Newport, Guinness' keeper of records. "We knew we had to have something pretty extraordinary given the nature of our business and we set out to capture the whole sense of 'wow' which surrounds the record book."
