Physicists have created a real-life prototype of an
invisibility cloak akin to the one featured in the "Harry Potter" books

Still, it's a nifty trick, and the physicists who've created the new cloak say it's a step closer to realizing the kind of invisibility cloak that could hide a person in broad daylight.
The invention is made of a new kind of material called a metascreen, created from strips of copper tape attached to a flexible polycarbonate film. The copper strips are only 66 micrometers (66 millionths of a meter) thick, while the polycarbonate film is 100 micrometers thick, and the two are combined in a diagonal fishnet pattern.
The creation is a departure from previous attempts to create invisibility cloaks, which have aimed to bend light rays around an object so that they don't scatter, or reflect off it.
