Can someone explain Van de Waals forces?

Van der Waals forces are the dipole-dipole interactions that exist between all molecules due to the natural movement of electrons within each molecule. They are relatively weak interactions, but are increase with a greater number of electrons interacting between the atoms of two separate molecules.

Although nonpolar molecules may have symmetrical electron distributions, there are instances when one area of the molecule is more negative than the other. This fluctuating electron distribution results in fluctuating dipoles. Van der Waals forces are the results of those instantaneous dipoles that result from fleeting asymmetrical electron distribution.
