• This paper reports on the interaction of a laminar round vortex ring with a sharp density interface. The deformation process of the ring after interacting with the interface was studied experimentally by both methods of the flow measurement by PIV and the flow visualization based on PLIF. For a 'weak' vortex ring compared with the density difference, having the Richardson number of the order of unity, the ring came to a stop near the interface and then displayed a complicated development. While this development of the ring deformation was similar as interacting with the solid wall, it should be also noted that the mass exchange between upper and lower fluids through the interface was observed in this experiment.
