30-year-old Liu Haibin is being hailed as the world’s coolest dad after he built an innovative seesaw that allows him to play with his toddler son who lives with his mother over 700 miles away.
While Chinese media is referring to Liu’s invention as the ‘world’s longest seesaw’, in reality, it consists of two identical seesaws equipped with motion sensors. One is placed in Tengzhou City, where Liu’s wife and eight-month-old son live. The other is with Liu, who lives in Xiamen City, 730 miles away. Through wireless internet signals and remote synchronization sensor data, the seesaws are perfectly synchronized. HD monitors on both seesaws enable father and son to see and interact with each other as they play.
