What is a meniscus? A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass. Adhesion is responsible for a meniscus and this has to do in part with water's fairly high surface tension.
Most liquids, including water, present a concave meniscus. A convex meniscus (sometimes called a backwards meniscus) is produced when the molecules of the liquid are more strongly attracted to each other than to the container. A good example of this shape of meniscus may be seen with mercury in a glass container. In some cases, the meniscus appears flat (e.g., water in some plastics).
