Worried about embarrassingly loud screams of fear at Halloween? Chupa Chups has the answer. As this video (via BBH Asia Pacific) being shown online and in cinemas explains, it's using 'lollipop technology to block embarrassing shrieks of terror at their source'. So, thousands of 'Scream Stoppers', in specially designed Halloween packages, have been distributed across Singapore at horror movie showings, haunted houses and other scary places.
