A US-British team of scientists has successfully tested a cloak of invisibility in the laboratory.
The device mostly hid a small copper cylinder from microwaves in tests at Duke University, North Carolina.
It works by deflecting the microwaves around the object and restoring them on the other side, as if they had passed through empty space.
But making an object vanish before a person's eyes is still the stuff of science fiction - for now.
