The Fifth Floor: Message in a bottle to North Korea

Park Jung-oh defected to South Korea from the North 26 years ago. Hearing how North Koreans in the Hwanghae Province suffer from food shortage, he started throwing bottles filled with rice and a USB stick into the Yellow Sea, hoping they would land on North Korean shores. Did his messages ever reach anyone? Rachel Lee from BBC Korean brings us this extraordinary story. Plus, Madina Dahiru Maishanu, the youngest presenter at BBC Hausa, shares stories from her award-winning show, Mahangar Zamani, and Thomas Naadi tells us about Stevie Wonder's love affair with Ghana.

Produced by Alice Gioia and Caroline Ferguson.
