It sounds like an excerpt from a Harry Potter book but German scientists say they've created a three dimensional invisibility cloak. The researchers from the Karlsruhe Institute of technology have hidden a bump on a gold plate using "metamaterials". The materials make the gold plate appear flat in infrared light. The research which is published in the latest Science journal is the first experiment to hide an object in 3D.
