Claim 3:
4. A device for producing a vortex ring in a liquid medium, said device comprising:
a housing containing a cylindrical chamber oriented vertically;
a column having a cylindrical cavity disposed beneath said chamber;
a piston contained within and movable along said cavity, said piston being movable by an external influence; and
a stack of interweaving anode and cathode rings, each ring having a circular through-hole, wherein
said stack is contained within said chamber,
said cavity and said through-hole in said each ring forming a continuous circular channel, and
said influence causes said piston to translate from said cavity into said stack to induce motion in the medium for said stack to generate a gas bubble around which the vortex ring forms.
