Scientists unveil ‘invisibility cloak’ to rival Harry Potter’s

Scientists at the University of Rochester have discovered a way to hide large objects from sight using inexpensive and readily available lenses, a technology that seems to have sprung from the pages of JK Rowling’s Harry Potter fantasy series.

Cloaking is the process by which an object becomes hidden from view, while everything else around the cloaked object appears undisturbed.

The so-called Rochester Cloak is not really a tangible cloak at all. Rather the device looks like equipment used by an optometrist.

When an object is placed behind the layered lenses it seems to disappear.

Previous cloaking methods have been complicated, expensive, and not able to hide objects in three dimensions when viewed at varying angles, they say.

In their tests, the researchers have cloaked a hand, a face, and a ruler – making each object appear “invisible” while the image behind the hidden object remains in view.

The implications for the discovery are endless, they say.

Although a patent is pending, they have released simple instructions on how to create a Rochester Cloak at home for under $100.
