Well, before you even excited about some of the magic invisibility cloak like Harry Potter, you need to know that so far the technology has not done a single thing to invisible: a bump on a gold bar.

Yes, it's a bump that only 0.00004 inches and 0.0005 inches in diameter, you'll probably see not only how it will look with a magnifying glass.

But it's start, and the researchers of the Karlsruhe Institute of Technology in Germany have succeeded in this little hump dress that could avoid detection at frequencies near the visible infrared. I'm not talking about stealth, but the effect of “cloaking” is visible in 3D view it from all sides.

How do they do it? Now the hair is a “crystal structure with air spaces between, like a pile of wood, which bends light, hid the bump later in the gold.” As you can guess, the size is important when it comes to something invisible, cloaking larger Objects with this technology is not really possible. ”

In other words, we are well ahead of our vehicles coat as the Romulans in Star Trek. However, I also experience the wonder and terror that we have the technology of invisibility, even if it is still in its infancy.
