Mercury sticks together because of the cohesive forces.

Water drops on a flower formed by cohesion (see full size image)

Cohesion or cohesive attraction or cohesive force in chemistry is the intermolecular attraction between like-molecules. Cohesion explains phenomena such as surface tension. Capillary action for example described in the Cohesion-tension theory related to botany is considered a mix of cohesion and adhesion. Cohesion is produced by the intermolecular forces. Mercury is an example of a liquid that has strong cohesive forces because its molecules would rather stick together. Another definable example of cohesion is the hardness of a diamond. The hardness results from the strong cohesive, or attracting, forces that attract the atoms together.Water is another example of cohesion.
