Dried coconut flesh is called copra, and the oil and milk derived from it are commonly used in cooking
Meniscus (liquid) the same radius, "r", as the inside of the tube. The tube experiences a downward force of magnitude 2πrσ, where σ is the surface tension of the liquid. Meniscus (liquid) The meniscus (plural: "menisci", from the Greek for "crescent") is the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension. It can be either concave or convex, depending on the liquid and the surface. A concave meniscus occurs when the particles of the liquid are more strongly attracted to the container (adhesion) than to each other (cohesion),
