Hydrostatic field

Hydrostatic fields, also called hydrostatic force-fields, were a type of energy membranes developed by the Gungans of Naboo. With those membranes, the Gungans created habitation bubbles that not only kept water out and contained breathable atmospheres, but also allowed individuals to pass through at special portal zones.
