There is a lot of news floating around about a British scientist who is trying to create an invisibility cloak. Most of the publicity is probably due to the fact that he mentioned Harry Potter .

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, Pendry said. He said the study was “an invitation to come and play with these new ideas.”

It’s not what you know, It’s how you market it.
