So basically, it\u2019s the closest thing to a man-made black hole. Point a flashlight at it, and you\u2019ll be checking to see if the batteries are dead. Now I know you\u2019re asking the next big question \u2026 what\u2019s it good for?<\/p>\n<p>A couple of ideas come to mind immediately \u2026 like lining the inside of telescopes to eliminate unwanted reflective light and of course, a coating for military aircraft and such. However, a more sinister use may be imagined. How about on Halloween night, wearing a full suit of this nano-fiber material you come walking down the street with only your disembodied head floating above the street. Years of nightmares for the kiddies you encounter.<\/p>\n<p>This bizarre stuff has been named \u201cVantablack\u201d.
