The world's tallest waterfall can evaporate before it hits the ground

Venezuela's Angel Falls drops water roughly 979 metres off the Auyan-tepui plateau, more than fifteen times the height of Niagara Falls. During drier months especially, much of that water breaks apart into fine spray on the way down and evaporates in open air, so the pool at the base receives only a fraction of what left the top.
