Researchers in the U.S. have, for the first time, cloaked a three-dimensional object standing in free space – bringing the idea of an ‘invisibility cloak’ a step closer.
The researchers used a hi-tech technique to ‘hide’ an 18-centimetre cylinder – and made it totally invisible.
But before we brace ourselves for Harry Potter-style invisibility to become a part of everyday life, it’s not quite there yet.
So far, the researchers can use a hi-tech coating to make an object disappear – but can only hide it from microwave scanners.
It’s still visible to the naked eye.
