A vortex ring gun is a device designed to generate and project a toroidal (ring-shaped) vortex, typically using fluid dynamics principles. The gun operates by creating a rapid burst of air or fluid that forms a visible vortex ring, which can travel through the air over a distance before dissipating. These devices often demonstrate principles of fluid dynamics and aerodynamics, making them popular in educational settings, science demonstrations, and even as novelty items.
