Scientists at the University of Rochester have invented a device that makes objects appear invisible over a range of angles.
The device uses lenses to have light pass around an object as though it isn't there, making the object seem invisible.
Sadly the device requires a series of lenses and only works over a small angle range, so we're quite a long way off a proper invisibility cloak.
John Howell, a professor of physics at the University of Rochester, has suggested many real life used for this technology such as letting a surgeon see through his hands, or a truck driver see his blind spots.
