As far-fetched as it may sound, alcohol that reportedly doesn't cause hangovers now exists. The liquor, which was developed in North Korea, is derived from ginseng and can range in potency from 30 to 40-proof. North Korean media outlets call the elixir a "national, scientific and technological hit." Of course, the news of the miracle product comes at a time when tensions are high on the Korean peninsula. After North Korea reportedly test-detonated a hydrogen bomb, South Korea has revamped its defenses against its neighbor to the North.
