Three hundred unmanned aerial vehicles were programmed to form images above the Han river -- which runs through the South Korean capital -- for the eye-catching flash mob. The show began with messages reminding people of key precautionary measures, including wearing masks, washing hands, and keeping a two-metre distance from others. The drones created images of a mask surrounded by coronavirus particles, quickly shuffling to form two hands and water droplets against the dark night sky. "THANKS TO YOU," the drones wrote in the sky next to a heart shape, then formed a silhouette of the Korean peninsula with the message: "Cheer up, Republic of Korea." The government-organized event on Saturday night was not advertised in advance in consideration of social distancing rules, the transport ministry said.
