The secret of Harry Potter's invisible cloak
Dr Andrea Di Falco poses for a photograph with a tiny piece of Metaflex material in a laboratory at St Andrews University, in Scotland November 5, 2010. A team of scientists at the university have created the Metaflex material which could be used to make fabrics that manipulate visible light to shield objects from view. Although the team of researchers are closer to unveiling an invisibility cloak, Harry Potter fans, and maybe sneak thieves, still have to wait way off before it come true. [Photo/Agencies]
