   1/2 liter of 30psi CO2 for 2 liters of H2O is not going to make very   
   carbonated water, unless that 30psi is maintained for a significant   
   time, like hours, unless broken into very fine bubbles as it is put into   
   the bottles. For my corny kegs, I have to add CO2 many times over   
   several days to get it properly carbonated, or I have to leave the CO2   
   tank valve open for hours.   
      
   1 liter at 30 psi is about 2 liters of CO2 at atmospheric pressure. Most   
   of that pressure will go away by the time the CO2 is dissolved in the water.
