Abstract
A liquid projectile apparatus is provided that is particularly apt for use in water displays in which liquid projectiles of a selectable size and shape are provided along variable trajectories at timed intervals or on demand. In one embodiment, the apparatus includes a liquid source, a housing assembly within which a mechanical discharge assembly is positioned, and a discharge positioning assembly. The discharge positioning assembly is provided for selectively positioning the housing assembly in various discharge positions to produce liquid projectiles with desired trajectories (e.g., discharge angles and directions). The liquid source supplies a discrete volume of liquid, with which a liquid projectile is formed, to the housing assembly. The mechanical discharge assembly is then operable to project the discrete volume of liquid from the housing assembly along a selected trajectory.
