Waterfall Droplets, Little Drops Cause Large Movement

Many water droplets fall, flowing down the terrain of Graffiti Nature - High Mountains and Deep Valleys. Then, those water droplets fall into the world below, flowing into the Universe of Water Particles on a Rock where People Gather.
When just one water droplet splashes, it bounces like a ball.
When the water droplets gather into a single body, they flow together and act like liquid water.
When water droplets separate from the body, they begin to behave like individual balls again.

Each one of the droplets, whether on its own or gathered with others, moves under the same simple rules of physics. However, when many droplets are gathered together, they behave in a way that could never have been guessed when dealing with individual droplets.
