A kinetic sculpture apparatus comprising a transparent tank filled with a transparent liquid and an air supply system wherein air bubbles are introduced along the bottom of the container and thus are distributed thorughout the liquid. Immersed in the liquid are a multiple of vessels that are substantially closed on their sides and top, and substantially open on their bottom. The vessels are weighted so that they have a negative buoyancy when holding a small amount of air but will become positively buoyant when they accumulate more air from the rising air bubbles. The vessels are also weighted so that their center of gravity remains below their center of buoyancy even when in a full positive state. The apparatus comprises techniques for releasing the air from the vessels at the top of their rise so that will sink back towards the bottom until they collect more air and rise again. Also techniques are provided for controlling the movement of the individual vessels and arranging certain vessels to move in sequence with others.
