Fed up with the indignity of passing through an airport scanner? Colorado inventor Jeff Buske claims he has the answer: scan-proof underwear. His strategically placed fig-leaf designs on his men's and women's briefs are made of a powdered metal that blocks the scan's rays, he explains. The thin, removable inserts conform to the body's contours, making it difficult to hide anything beneath—and the components don't set off metal detectors, AP reports. It's not yet clear if the undies will fly with airport security.
