Seoul you wanna start a revolution

Seoul you wanna start a revolution: I thought this was super interesting. Korean activists are using 3D-printed smart balloons to send messages deep into North Korea. Each balloon costs up to $1,000 and can carry up to 16.5 pounds of cargo, like leaflets or mini speakers. The mission: Undermine dictator Kim Jong Un.
