This paper describes a method for producing cyclic liquid jets in pulsating bubbles that have been acoustically trapped near a platform in a vibrating container. The ambient pressure above the liquid is reduced to near that of the vapor pressure of the liquid, and vapor-air bubbles driven near resonance size at 60 Hz develop large pulsations that can readily lead to jet development. Photographs are presented of various aspects of jet production as well as of some intriguing displays of bubble surface oscillations.
