Get this, this material reflects a whopping 99.96% of all light.  The material on this foil paper has creases in it, but your eye sees nothing but darkness.  The military and other private ventures are lining up to get a piece of the action.  My guess, it’s probably a dead ringer for more advanced stealth.  Can you imagine using this at night as some sort of cloak, or for drones for that matter.  Unbelievably interesting stuff!
