what is a meniscus ( science term)
Water Meniscus. 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. Why a meniscus occurs. Adhesion is responsible for a meniscus and this has to do in part with water's fairly high surface tension.
