Water drops on a leaf Water drops falling from a tap. A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces.A drop may form when liquid accumulates at the end of a tube or other surface boundary, producing a hanging drop called a pendant drop.
A rainbow is a narrow, multicoloured semicircular arc due to dispersion of white light by a multitude of drops of water, usually in the form of rain, when they are illuminated by sunlight. Hence, when conditions are right, a rainbow always appears in the section of sky directly opposite the Sun.
Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation. [1] As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets. [2]
The animation (below) shows water adhering to the faucet gaining mass until it is stretched to a point where the surface tension can no longer keep the drop linked to the faucet. It then separates and surface tension forms the drop into a sphere. If a stream of water were running from the faucet, the stream would break up into drops during its ...
Fog collection is the harvesting of water from fog using large pieces of vertical mesh netting to induce the fog-droplets to flow down towards a trough below. The setup is known as a fog fence, fog collector or fog net. Through condensation, atmospheric water vapour from the air condenses on cold surfaces into droplets of liquid water known as ...

Higher contact angles indicate less contact between the water and glass, contributing to hydrophobicity. High water-sliding property of WRG films is necessary for hydrophobicity. [2] The higher the water-sliding angle, or angle of a surface in which a water droplet begins to slide down, the easier a water drop can slide down the film surface.
