At this rate, Harry Potter skeptics may soon be left with no place to hide. Two new materials that bend light backward suggest that invisibility cloaks like Harry's could some day become feasible.

"That goal is to bend light in the opposite direction than it would when entering an ordinary material."

The possibility of reverse bending has been known for decades, but it wasn't until 2000 that scientists demonstrated materials that could do the trick. The first demonstrations worked for microwave radiation, which has longer wavelengths than those of light. And last year, the first materials began to appear that could bend visible light backward.
