                  MAKING CLOUDS

               Rain is crucial to our Earth, especially for growing   Silver coin
               healthy crops. Where there are no clouds, scientists
               can form tiny water droplets that cling to silver
               iodide powder, forming artificial rain clouds.

                       water droplets in a cloud
                         become heavy enough.
