New Real Life Invisibility Cloak Created in Germany


We’ve all wanted to disappear for one reason or another, but we never had an awesome cloak like Harry Potter. Researchers have engineered a fabric that hides from sight by bending the light around it. Well, we are close to being able to escape awkward situations in a magical cloak because of the research done by scientists from KIT! At the Karlsruhe Institute of Technology, in Karlsruhe, Germany, have created the ever anticipated portable invisibility cloak! This fabric is very small however and can only hide small objects. It is often used in classrooms for demonstrations, in order to inspire awe, well that’s what I would use it for.

In order to divert light around an item to make it seem invisible, we have to figure out a way to compensate for the new distance the light has to travel. Because of the properties of relativity, mass is prevented from going faster than the speed of light, you cannot go faster than light in a vacuum or in air. In order to create the ‘invisibility cloak’ and solve this problem, the scientists at KIT created the fabric out of a light-scattering material. Scattering light, the act of creating random paths for energy, made the fabric slow the effect of the light waves. Next, the light goes around the object, rendering it… invisible!
