Check out this gorgeous waterfalls that were installed recently in the Banpo River in Seoul South Korea. The 10,000 nozzle fountains built several feet apart on both sides of the Banpo bridge spurt out jets of water that periodically change color, turning the installation into a really attractive water rainbow. The installation pumps out 190 tons of water per minute, sourced from the Banpo River below so that no potable water is wasted.
