Why does North Korea keep sending waves of balloons full of trash towards South Korea

North Korean balloons containing trash again entered South Korea on Wednesday, drifting into the presidential complex grounds in Seoul. The presidential complex is located in the central Yongsan area of the South Korean capital. Seoul is located only 35 miles (56 kilometers) from the demilitarized zone (DMZ) between the two Koreas.

They do it because South Korea broadcasts propaganda into the North.
