A group of scientists at Purdue University in Indiana (USA) have finally come up with a workable design for an invisibility cloak. Last year, scientists figured out a complex equation for making objects appear invisible by making light bend around them, but now they've managed to take it further...so much so that they may even be able to make objects as large as an aeroplane invisible!

"It looks pretty much like fiction, I do realise, but it's completely in agreement with the laws of physics," said lead researcher Vladimir Shalaev, a professor of electrical and computer engineering at Purdue.

"Ideally, if we make it real it would work exactly like Harry Potter's invisibility cloak," he said. "It's not going to be heavy because there's going to be very little metal in it."
The still-theoretical design will be published this month in the journal Nature Photonics.
