For fans of the fictional Harry Potter, US and British scientists have demonstrated a working "invisibility cloak" that could, in time, make wearers disappear. Initial tests focused on making objects invisible to microwaves, but the scientists said the same principles could theoretically apply to visible frequencies, making a true invisibility cloak like storybook hero Potter's possible.

Scientists are boldly going where only fiction has gone before to develop a Cloak of Invisibility. It isn't quite ready to hide a Romulan space ship from Capt James T Kirk or to disguise Harry Potter, but it is a significant start and could show the way to more sophisticated designs.

In this first successful experiment, researchers from the United States and England were able to cloak a copper cylinder.

It's like a mirage, where heat causes the bending of light rays and cloaks the road ahead behind an image of the sky.

"We have built an artificial mirage that can hide something from would-be observers in any direction," said cloak designer David Schurig, a research associate in Duke University's electrical and computer engineering department.
