Methods and apparatus for adjusting a delivery, distribution, emission, or spray of an adaptable material are disclosed. The adaptable material is contacted by a compatibly-selected kinetic energy fluid. The contact provides a motive force to move the adaptable material to or from an outlet of a spray fixture. The spray fixture is adjustable to emit various forms of drops, mists, extrusions, emulsions, or fibers. The adjusting is based on characteristics of a feedstock material, the adaptable material, the compatibly-selected kinetic energy fluid, or combinations thereof.
