Condensation is the change in the phase of matter from the gaseous phase (of an element/chemical species) into liquid droplets or solid grains of the same element/chemical species. Upon the slowing-down of the atoms/molecules of the species, the overall attraction forces between these prevail and bring them together at distances comparable to their sizes.

Lois watches a television show called Condensation on BBC Four while in London in "Patriot Games". The show depicted is a parody of the channel’s intellectual, esoteric content.
