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 ...
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]
Tears of wine show clearly in the shadow of this glass of 13.5% Caluso Passito dessert wine. The phenomenon called tears of wine (French: Larmes de vin; German: Kirchenfenster, lit. "church windows") is manifested as a ring of clear liquid, near the top of a glass of wine, from which droplets continuously form and drop back into the wine.
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.
Santa Claus is front and center in this display within a window display circa 1920s that's all about toy trucks, cars and bikes. Fun fact: The Emigh-Winchell Hardware Company in Sacramento, CA ...
Slow motion video of a fruit falling into water. In fluid mechanics, a splash is a sudden disturbance to the otherwise quiescent free surface of a liquid (usually water).The disturbance is typically caused by a solid object suddenly hitting the surface, although splashes can occur in which moving liquid supplies the energy.
With small tilting angles, water droplets on the leaf roll off and take any dirt or contaminant along, leading to self-cleaning. [18] The ability of drops to form and roll off, depends not only on hydrophobicity, but also on contact angle hysteresis. In plants world, the lotus leaf is not the only example of natural superhydrophobic surfaces.
Glory around the shadow of a plane. The position of the glory's centre shows that the observer was in front of the wings. A glory is an optical phenomenon, resembling an iconic saint's halo around the shadow of the observer's head, caused by sunlight or (more rarely) moonlight interacting with the tiny water droplets that comprise mist or clouds.
