Mercury is a metal unlike water which have hydrogen bonding. Mercury does not wet most substances, because of its high cohesion and low adhesion to the glass mercury will not wet glass. Cohesion, along with adhesion(attraction between unlike molecules), can help explain mercury phenomena. Mercury has a surface energy over 6 times greater than that of water so there is a much greater attractive force between the atoms of mercury than between the molecules of water, so mercury does not wet glass.
