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. Drops may also be formed by the condensation of a vapor or by atomization of a larger mass of solid ...
Water on the surface of a lotus leaf. Water droplets on taro leaf with lotus effect (upper), and taro leaf surface magnified (0–1 is one millimetre span) showing a number of small protrusions (lower). Computer graphic of a lotus leaf surface. A water drop on a lotus surface showing contact angles of approximately 147°.
Alternative names for these systems are often used, such as transparent emulsion, swollen micelle, micellar solution, and solubilized oil. More confusingly still, the term microemulsion can refer to the single isotropic phase that is a mixture of oil, water and surfactant, or to one that is in equilibrium with coexisting predominantly oil and ...
The effect becomes apparent when water droplets are involved that have a diameter of about 1 mm or less; the smaller the droplets are, the broader the supernumerary bands become, and the less saturated their colours. [41] Due to their origin in small droplets, supernumerary bands tend to be particularly prominent in fogbows. [42]
GIF animation of an Apollonian sphere packing with transparent background. Transparency in computer graphics is possible in a number of file formats.The term "transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible.

Hard rime forms by rapid freezing of supercooled water under at least moderate wind conditions. The droplets freeze more or less individually, leaving air gaps. Clear ice forms by slow freezing of supercooled water. Clear ice is typically transparent and homogeneous. Its amorphous and dense structure makes it adhesive.
GIF was one of the first two image formats commonly used on Web sites, the other being the black-and-white XBM. [5] In September 1995 Netscape Navigator 2.0 added the ability for animated GIFs to loop. While GIF was developed by CompuServe, it used the Lempel–Ziv–Welch (LZW) lossless data compression algorithm patented by Unisys in 1985.
