If you believe this article the invisibility cloak could soon be a reality. Researchers at the University of California have developed a material that can bend light around an object making it disappear. Obviously the item doesn't actually disappear it is simply no longer visible. The effect is based upon reversing refraction and the result is that only white light behind the object can be seen giving it a cloaking effect. The team involved have said that the principle could be scaled up to make one day make a cloak large enough to hide people. Interesting. Now what would I do with an invisibility cloak?
