U.S researching Harry potter Technology

This morning i was listening to radio FM, i heard from the DJ, U.S is currently researching on a material that make thing go invisible, just like the invisible coat that harry potter have. The material is not natural, it have to be created. What the material does is, it bends the light ard the object, thus "allowing" light to pass through, making the object invisible.

As u know, when ever U.S fund such project, its is usually by the military department. Most probably they will use it on tank.

In the future, a platoon of artillery unit can shell without anybody seeing it. and that's so damn gay.
