      A concave (smile-shaped) meniscus occurs when the particles of the liquid are more strongly attracted to the material of the container than each other.
      A convex (rainbow-shaped) meniscus occurs when the particles of the liquid are more strongly attracted to each other than to the material of the container.
      So this happens with water in a container because water is a liquid.
