Now you can buy the "Harry Potter" invisibility cloak - and that's the price you'll pay for it - voila! technology. Invisibility Shield Co based in London recently launched the "Mega-Shield", a 1.80 meter high invisibility shield that is big enough to hide several people.
The disappearing shield works with the help of engineered lens arrays with extremely high precision on its front. The redirected light is reflected from the person standing behind it, away from the viewer on the other side.
