   What is the secret to how the soda stream works to carbonate water at home?   
   Why does it work in only about fifteen seconds (three to five squirts)?   
      
   How can I replicate that squirty nozzle using typical air compressor   
   fittings (like an air gun of sorts, but with that long thin nozzle)?   
      
   I already built a simple carbonation system using a 5 pound C02 tank, a   
   carbon dioxide regulator, air pressure hose quick connects on beverage   
   pressure hose, and a plastic soda bottle cap drilled in the center with a   
   metal tire valve locked in place (without the inner schrader valve core so   
   it's just a pipe with rubber gaskets that can be tightened on both ends.   
      
   That works to carbonate ice cold water in a plastic liter coke bottle but   
   it takes about five minutes at about 50 psi or 60 psi even after squishing   
   the bottle to get all the air (mostly nitrogen) out of the bottle so it's   
   just carbon dioxide in the air space above the top part of the plastic soda   
   bottle where it starts to curve inward and even after swirling & shaking to   
   get more surface area of the water in contact with the carbon dioxide gas.   
      
   I'm guessing the secret to the soda stream is that it is unregulated?   
   And that all that unregulated carbon dioxide goes into a teeny tiny nozzle?   
      
   If the sodastream is unregulated, then I'm guessing the sodastream squirts   
   the carbon dioxide gas at a bit over 800 psi up to over 1,000 psi (or even   
   2,000 psi depending only, I think, on the temperature and amount of liquid   
   in the carbon dioxide tank) through that teeny tiny nozzle.   
      
   Does it?   
      
   Short of taking a sodastream apart and reusing its fittings, and short of   
   hooking the five pound carbon dioxide tank directly to a sodastream machine   
   (which I don't have), what common air hose fitting can I find that squirts   
   the carbon dioxide (unregulated?) into the bottle through a similar teeny   
   tiny nozzle?   
      
   Since I'm using car tools (such as the compressor fittings), I'll add them.
