Scientists Bend Light To Make Object Invisible

Researchers at the University of Birmingham and at MIT have successfully used naturally forming calcite crystals to render objects invisible. In the Birmingham experiment, a paper clip was rendered invisible when a composite crystal was placed over it. By gluing together two calcite crystals with opposite crystal orientations, the latter reflected and refracted the light coming through in such a way as to conceal the paper clip on the other side, making it appear as though it wasn’t there.

Since the calcite crystals can grow well over a dozen feet long, it is theoretically possible to conceal a person or even an average New York City apartment!
