Water spouts are natural or artificial structures that release water into the air, creating a visually appealing display. They can be found in various settings, such as parks, gardens, and fountains. Water spouts can vary in size and design, from small decorative features to large installations that shoot water high into the sky. In nature, water spouts can also refer to geysers, which are hot springs that erupt with steam and boiling water. These phenomena occur when underground water is heated by geothermal energy, causing pressure to build until it is released. Famous examples include Old Faithful in Yellowstone National Park.
