Hydrostatic bubble technology was developed by the Gungans when they were forced underwater by the Grizmalltian colonists who dominated Naboo. The bubble functioned by projecting a membrane-field which displaced water and prevented the entry of foreign objects through the bubble's except at specific entry portals. The base of each bubble was comprised of a lightweight alloy lattice and transparisteel that contained the bubble's generator. Varying in size, the average-sized bubbles were projected by utanodes; while larger versions were generated by a kernode assembly.  The underside of the base consisted of a long, pointed spire where counterweights and repulsor field generators worked to keep the bubble upright and stable.
Behind the scenesEdit
