Interesting video captured a water fountain in northern China being controlled by tourists' voice volume.<br /><br />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.<br /><br />The fountain is called Shout Fountain, which is located at Cangshan Scenic Area.<br /><br />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.
