The Gunfighter

Normally I like to let it slide, but it is a tedious job being a gunfighter. I stand my ground and make no sudden movements, and ease my hands very slowly. Than I move like lightning and the bullets start to fly. With any skill, my opponent misses with just inches left to spare.
If I screw up, well than I need not mention that. Imagine my surprise when I discovered that a new stealth material was on the horizon. It is known as a metamaterial and it exhibits the sexy characteristic of being left-handed. To you jackasses out there, it is not what you think! Left-handed materials display the cool talent of having a negative refractive index, which equates to the ability to refract light at an angle opposite to its incidence.
This means that you can refract light rays around an object, a slick trick by any standards. To completely hide an object you would have to enclose it in a shell of the material, but if it means winning that count me in. The invisibility cloak of the Harry Potter series might be built someday, but it is unlikely to be so benign. The currently available material for visible light is Opal, which is composed of a metastable silica spheres. A metastable structure is a non-stable system that can persist in that state for a long period of time. The last type of known metamaterials is susceptible to microwave radiation, and it is artificial, built of arrays of conducting wire loops.
It is unavoidable that in time these magical materials will come into regular use by the military, and in time by everyone else. Than perhaps it’s not magic, just science being utilized by the magical human mind.

I'm disappointed. Now Harry Potter does not seem all that magical. I thought a trick like that would be much harder.
