For those that don't want to read that rubbish, here are the highlights.

The invisibility cloak worn by Harry Potter in a series of books by J.K. Rowling is theoretically possible, US and British researchers say.

The cloak theoretically could be achieved by using exotic artificial composite materials called "metamaterials", they said.

But first they would have to make the metamaterials, which would deflect light and sound and other force waves.

"It's theoretically possible to do all these Harry Potter things, but what's standing in the way is our engineering capabilities," John Pendry of Imperial College London, co-author of the study.
