A giant water cannon sprays water into the air in Zhangjiakou of Hebei province on July 7, 2014. The machine can spray water a distance of up to 60 meters high. The water goes up as a fine mist and sticks to dust to form larger particles, which fall to the surface under force of gravity, experts said. The city is in a joint bid to host the 2022 Winter Olympics with Beijing. [Photo: Official Sina Weibo account of Xinhua]
