1. A bubble generator comprising:
a container including a side wall and a top wall defining a cavity having a volumetric dimension at an initial pressure;
an insert located within the cavity defining a gas path with a trap portion, the gas path being in communication with an exit in the container; said insert having a diameter equal to or less than the horizontal plane of the container;
the cavity including an opening receiving a gas accumulating within the cavity, said cavity capable of receiving said accumulating gas and the gas expanding to a predetermined volume proximate to a trap exit level,
the gas accumulating within the cavity and displacing a liquid internal to the cavity,
the gas path of the trap allowing the accumulating gas to escape through the exit once the accumulating gas reaches said predetermined level proximate the trap portion,
wherein said cavity returning to said initial liquid volume and pressure once the accumulating gas escapes,
wherein a liquid path merges with the gas path at an acute angle between the trap portion and the exit
wherein the sum of the cross-sectional area of the liquid path and the cross-sectional area of the gas path at the point of merger of the gas path and the liquid path is equal to or smaller than a cross sectional area of the exit.
