Buy three new 9 volt batteries; should be identical.
 
Buy two alligator clips (about 1 1/2 feet long) from Radio Shack, or  
wherever.  These are wires covered with plastic, and a metal clip at each  end.
 
Get two silver sticks .999 pure or similar purity.  Can be sticks or  
flattened, but they should be about 6 inches long.
 
Get a pint glass measuring cup (grocery store).
 
PROCEDURE:
Snap batteries together with contacts facing each other.  There is  only one 
way they can go.  This will leave two leads free.  Attach one  alligator clip 
to each free lead.  Attach a silver stick to the other end  of each alligator 
clip.  Fill the glass measuring cup almost to the top  with drinking water 
(not distilled as there are no ions to conduct the  electricity, and nothing 
will 
 happen, at least not for hours).  Place  the silver sticks in the water, not 
touching each other, taking care not to get  the metal alligator clip in the 
water (you don't want to make lead  colloid!).  One silver stick will collect 
bubbles, and the other will exude  a gray cloud.  If this doesn't happen 
pretty soon, review the above steps  and correct anything that deviates from 
the 
above instructions.  Another  reason nothing may happen is that the water is 
too 
pure (too close to  distilled).  Use another type of drinking water.  Stand 
there and  watch the process, as it may only take 1/2 minute to 3 minutes to 
make the  CS.  When the water is only slightly gray, take the silver sticks out 
of  the water, and stir the CS with the silver sticks.  Do not stir with  
anything else.  Remove the alligator clips from the batteries.  The  batteries 
may 
be stored snapped together, but if the alligator clips are left  attached, it 
will run down the batteries.  Do not store anything wet next  to the 
batteries, or they will be corroded.  Using the nylon backing of a  sponge, rub 
the 
silver sticks under running water to remove the dark  color.  
 
Either drink the CS immediately, or store the remainder in the dark.   This 
type of CS will be destroyed by light in 8 minutes, I have been told.   
Therefore, don't make it under bright lights.  I typically drink it the  same 
day I 
make it, and storing it in the cupboard until it is  gone. 
 
Best of luck,
