Title: Meniscus of Water and Mercury
Caption: Meniscus of mercury (right) and the meniscus of water (left). Mercury molecules attract one another more strongly than they attract the molecules of the container, so they form a convex meniscus. Water molecules are attracted to the glass container by capillary action, so they form a concave meniscus.
