Using technology designed to make solid objects vanish from sight, a team of US and British scientists have built the world's first cloaking device. It works like a mirage, where heat causes the bending of light rays and cloaks the road ahead behind an image of the sky.
However, David Smith, who led the experiments, said: "It's not yet clear that you're going to get the invisibility that everyone thinks about with Harry Potter's cloak or the Star Trek cloaking device."
"The cloak reduces both an object's reflection and its shadow, either of which would enable its detection."
cool na..
