Scientists create actual, fully functional invisibility cloak

Apart from meeting Daniel Radcliffe, many fans of J.K. Rowling's popular Harry Potter franchise would be hard pushed to find an experience that is closer to a real-life fantasy of the books and films than using an actual invisibility cloak.

Well, they may be in luck. Scientists have recently managed to create a piece of fabric from gold-etched silk that, officials at Tufts and Boston University say, may have some properties of invisibility.

"Unlike most materials, which derive optical properties like color from their chemical make up, metamaterials derive their properties from the physical structure," Discovery News writes.

The development seen in the study is said to be used for biochemical purposes, although the scientists who have developed the technology say they are also exploring opportunities within defense. 

Popular Science explains how it works.
