How about getting invisible, probably this was always a childhood dream of mine. Nanotechnology has gone ahead to realize this dream of a lot of us by creating an optical cloaking device which can make objects invisible by moving light around whatever is placed inside this cloak. In this case engineers from Purdue University have created a theoretical design for use in a range of tiny needles radiating outwards from a central spoke.
The designing is similar to a round hairbrush bends light around the object being cloaked and in this case one can see the background object but not the objects surrounded by cylindrical array of nano needles. Keep one thing in mind that the design can work just for the single wavelength and not for the whole frequency range of the visible spectrum. Objects could be rendered invisible in a wavelength of 632.8 nanometers corresponding to the red color. This design could also be used for cloaking other single wavelength in a visible spectrum. The device is expected to be created from non magnetic meta materials. So now get ready for invisible game.
