Now you see it
Scientists have created an invisibility cloak.
Well, almost. They can make things invisible to microwaves. Doing it with light is a little more difficult. Its to do with wavelengths. Light has a wavelength of less than a micron as opposed to microwaves 3cm. Since your meta material (that you make your cloak from) must have a internal particle size of less than your wave length this make an optical cloak pretty tricky. But given the recent breakthroughs in nano technology not impossible. Should have an invisibility cloak on the shelves in about 40 years time.
Damn, I may be to old to fully appreciate girls changing rooms by then.
