Abstract
An underwater device for generating a vortex ring includes a liquid chamber, and a fluid or air chamber contiguous to the liquid chamber and separated by a partition wall. The liquid chamber includes a generally rigid section and a compressible or flexible section. The rigid section includes an opening for selectively loading the liquid chamber with a liquid and for discharging a vortex ring therefrom.
