There are many kinds of drops; spilled drops, rain drops, dew drops. The source of drops also varies: rain, waterfalls, fountains, dew.
Steam - water as a gas - is invisible. When temperature drops, water returns to its liquid shape. Above as clouds, below as dew.
When drops are tiny but many, dew blurs the surface. However, small drops unite to create larger drops.
And when they are big enough, drops also acts as lenses.
