Harry Potter's Wardrobe...

Last year i read an article on the web version of "The Telegraph", that mentioned scientists have developed a prototype "invisibility cloak", similar to those worn by fictional wizard Harry Potter. 

I found a lot of papers and researches from different scientists and universities around the world. These are the ones that i find more worth mentioning.I don't pretend to know anything about all this science involved but it goes something like this. People and objects reflect light and that light makes us visible. 
According to American scientists  a combination of materials re-direct that light making it difficult for a man or an object to be seen.Japanese scientists take it one step forward and use reflective projection technology using a computer, a video camera and a projector that shows background images onto the front (something like the Apple ipad app "rubbing away your ipad screen"). An amazing fabric made of glass beads that can reflect light back to the source. 

Scientists at the University of St. Andrews in Scotland have developed "smart flexible materials" named meta-flex that are made of tiny meta-atoms, which are engineered mixtures of metal and circuit board materials.

These interact with visible light, changing the way the eye perceives an object by reducing its reflection and shadow.The researchers believe that the discovery could pave the way for the creation of "invisible" clothing. Previous studies involving the development of such clothing have been funded by military groups.

The inventions that had been engineered until now involving invisibility, could only exist on flat, hard surfaces rather than flexible ones. The Scottish researchers were able to develop a way of separating the atoms from the hard surfaces, allowing them to be used in creating flexible products like fabric.

The research was published in November's 2010 issue of New Journal of Physics.

Breaking News: The latest issue of New Journal of Physics(January 2012)published a new paper about this subject. Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space.

So, a lot of scientists are interested in making an "invisible cloak", that's for sure! And i think, a lot of us have wished at least once in our lives to be invisible...be patient my friends...it seems the much-talked-about invisibility clothing  is coming one step closer to reality.
