Water is a unique molecule thanks to its chemical properties. Since water has a dipole (negative in the Oxigen side, positive in the Hidrogens) it is able to create weak electrostatic interactions between H -O of diferent water molecules (also called "Hidrogen bridges"). This weak interactions, are scaled in strenght when you consider the total amount of water molecules. Thus, we can conceive water as an "electrostatic mesh", comprised of this electrostatic interactions, which allow lubrication and cohesion between the molecules.
