Embodiments of the systems and methods disclosed here are generally directed to anti-stringing systems that can be used in the application of a substance to a work surface. In one embodiment, an anti-stringing system includes an applicator having a nozzle for applying a substance to a work surface and a gas port configured to deliver a gas flow that disrupts the flow of the substance. In some embodiments, the gas port is located at least partially internally of and coaxial with the nozzle such that the substance flowing from the nozzle envelops one end of the nozzle. In other embodiments, the invention concerns hand-held glue guns having anti-string systems. In yet other embodiments, methods for breaking substance strings are disclosed. One such method includes delivering a gas flow that is substantially coaxial with the direction of flow of the substance. Various inventive embodiments relate to methods and devices for delivering a gas flow to a gas port.
