Meniscus (liquid)
Videos
In physics, the meniscus is the curve in the upper surface of a liquid close to the surface of the container or another object, produced by surface tension.
A meniscus as seen in a burette of colored water. '20.00 mL' is the correct depth measurement.
Capillary action

Capillary action is the process of a liquid flowing in a narrow space without the assistance of external forces like gravity.

…marks to account for the meniscus. This means that any instrument is calibrated for a specific liquid, usually water. Menisci are a manifestation of capillary action, by which either surface adhesion pulls a liquid up to form a concave meniscus, or internal cohesion pulls the liquid down to form a convex meniscus…
Capillary water flow up a 225 mm-high porous brick after it was placed in a shallow tray of water. The time elapsed after first contact with water is indicated. From the weight increase, the estimated porosity is 25%.
