1. A disperser, comprising: (a) a disperser body; (b) a collapsible pouch containing a liquid fluid; (c) a disperser cap assembly configured to form a substantially air tight seal with the disperser body so as to define a chamber therein, the pouch disposed within the chamber and engaging the disperser cap assembly, the disperser cap assembly defining a passage in fluid communication with the chamber, the passage also in fluid communication with a valve disposed in the disperser cap assembly, the disperser cap assembly also including a coupling in fluid communication with the valve and configured to puncture a portion of the pouch so as to put the valve in fluid communication with the liquid fluid, the valve opening to a nozzle, the chamber configured to contain a gas at a pressure that is greater than ambient pressure external to the chamber so that the gas in the chamber applies a pressure to the pouch; and (d) a valve trigger configured to fluidly couple the passage and the coupling to the nozzle so that gas from the chamber flows through the passage into the nozzle and so that the liquid fluid flows into the passage and is entrained by the gas flowing through the passage, such that a gas and fluid suspension is forced out of the nozzle,
