Magic has turned into reality. A remarkable achievement has been made by an American team: the world's first real invisibility cloak, a device turning an object invisible in the visible spectrum. But don't get your hopes up: the technique works only in two dimensions and on a tiny scale so far.
The new cloak is only 10 micrometres wide and heads light waves around an object located inside, releasing them on the other side. The light's trajectory seems right, so the cloak and objects inside become invisible.
