You simply have to control the rate at which the acid reaches the sodium 
bicarbonate.   This in turn would regulate the pressure in the reagent 
vessel.  Control the output by a combination of "Drip rate" and some output 
flow control.  The real problem with vinegar and baking soda is the volume of 
reagents necessary to achieve the same CO2 output as other reagents.
