Hi guys:
 
I don't understand any of this technical stuff, but have been making CS for  
years with my home-made kit--three 9-V batteries snapped together, alligator  
clips connecting the free leads of the batteries to silver wires, and putting  
the wires in a glass measuring jar of tap water.  Depending on the hardness  
of the water, the water turns ever so slightly gray in 30 seconds to three  
minutes, and there you have it!  The "apparatus" keeps nicely in a  sandwhich 
bag.  No rocket science here!
