Invisibility Cloak That Bends Light to Be Made

Scientists have finally claimed to be able to make an invisible cloak much like that used by wizards like Harry Potter in the popular movie series. No, it won't be magical, and no, it's not one of those flexible LCD-like cloaks that show an image of what's behind whoever it is looking at you (left picture). This new cloak will actually bend light like how those aliens in the Predator movies do. Their explanation is rather sketchy but the engineers at Purdue University in Indiana say they will "fit tiny needles into a hairbrush-shaped cone at angles and lengths that would force light to pass around the cloak." Lead developer Vladimir Shalaev says that it is pretty much like fiction but that the principle agrees with the laws of physics. The applications of the cloak are tremendous, from military to who knows what else.
