As one of the easiest ways to help stop the relentless spread of coronavirus (or any virus) across the world, scientists and governments are desperate for as many people to wear face masks as possible. Campaigns have ranged from sarcastic signs aimed at those that don’t wear masks, to everyone's favorite uncle, Tom Hanks, having stern words, to businesses outright banning people without them. South Korea is trying a more creative approach. In a stunning display of gratitude towards medical personnel and members of the public, South Korean officials put on a 10-minute drone show that lit up the sky in Seoul. Three hundred drones were programmed to create aerial images showing the importance of wearing masks and washing hands, thanking medical workers, and displaying various messages to the impressed onlookers. The show was an incredible display of technology and quite simply awesome to watch, but it also carries an important message – wear masks and save lives. Source
