Mathematicians Design Invisible Tunnel

New calculations show how to make an electromagnetic "wormhole" — a tube that is invisible from the sides but allows light to shine down the center. The practical applications are a ways off, as even the design of a spherical invisibility cloak has not advanced beyond working (in theory) for a single wavelength of visible light.

Did you people all flunk math? Those are MODELS of a Klein Bottle, not a REAL Klein bottle. The Klein Bottle is a construct that cannot exist in normal 3D space.
Now I suppose you're going to tell me that a drawing of a cube on a piece of paper is a real 3D cube?
