This water fountain in China is controlled by tourists' voices

Interesting video captured a water fountain in northern China being controlled by tourists' voice volume.

The clip, shot in Yangquan City in Shanxi Province on May 1, shows a woman shouting loudly into a box at the side of a river. Then the water can be seen spraying up into the air gradually with her voice volume.

The fountain is called Shout Fountain, which is located at Cangshan Scenic Area.

Due to the pressure of the groundwater as well as the infiltration and syphonage of the pores between the rocks and soil, the water sprays out to form a fountain.
