Scientists developing real life invisibility cloak

An invisibility cloak similar to the one Harry inherited from his father in the first book may not be far off from reality. Researchers in the US and England are laying out a blue print and collecting the exotic materials needed to build such a cloak. John Pendry, a physicist at the Imperial College London said, "Such a cloak does not exist, but early versions that could mask microwaves and other forms of electromagnetic radiation could be as close as 18 months away.... We will have a cloak after not too long." Thanks to everyone who wrote in!
