Drop (liquid)
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 lower 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 liquid.

Famous quotes containing the word drop:
“Parents who want a fresh point of view on their furniture are advised to drop down on all fours and accompany the nine or ten month old on his rounds. It is probably many years since you last studied the underside of a dining room chair. The ten month old will study this marvel with as much concentration and reverence as a tourist in the Cathedral of Chartres.”
—Selma H. Fraiberg (20th century)
