Abstract

A system for delivering vortex rings to an intended target includes a vortex ring generator, one or more component storage containers, and a component additive mechanism. The vortex ring generator is configured to deliver and air vortex rings. The component additive mechanism is configured to remove a component from at least one of the one or more component storage containers, generate a gas from the component, and to add the gas to a vortex ring after the vortex ring is generated by the vortex ring generator.
