A father in China has come up with an ingenious way of playing with his young son despite being hundreds of miles apart.

Liu Haibin, 30, has invented what the Chinese media are calling the 'world's longest seesaw'.

The seesaw uses technology so that Liu can play with his eight-month-old son in Tengzhou City in north China - 730 miles away from where he lives in Xiamen City, according to local media

To create the see-saw, Liu put two identical versions of the toy in Xiamen, south China and Tengzhou, north China.

By using wireless internet signals and remote synchronisation sensor data, the seesaws work perfectly as though they were one - despite the enormous distance separating them.

HD televisions on the seesaws mean father and son can interact with each other as if they were only a short distance apart.
