The exterior equilibrium of the wall is designed such that during daylight hours a thin external layer of dihydrogen oxide along the outer surface of the wall will sublimate into the atmosphere. The shedding of this harmless chemical in its natural form will not cause any side-effects detrimental to human life.

During the night-time hours, the same equilibrium which allowed for sublimation from the surface of the wall will support the slow crystallization of fresh and beautiful dihydrogen oxide material. The daily steady sublimation / recrystallization of the surface will guarantee that it continues to maintain its beautiful glossy appearance despite attempts to deface the wall with graffiti or other markings.
