Three ( 3 ) nine volt batteries. Buy some now, or scrounge
them later from your smoke alarms. You can always put them back..
If you don't have three alarms, borrow from a neighbor. You can trade
silver water for the use of them. With smoke alarms, test the batteries
before removing them; just press the button and listen for the beep.
Two electrical wires, 16" long (or so) You can cut these from
a lamp cord if you have to (unplug first).
Two or more paper clips
Two or more alligator clips would be nice, but not necessary.
Tape. Also, two rubber bands, if you have them
12" (1 foot) of fine silver wire, either .999 or .9999
Assembling the battery pack:
Tape the three (3) nine volt batteries together in series like
this:  . This triples the rated voltage to 27 volts.
To do this, place batteries with their terminals in the following
( x = positive o = negative)
In other words: just line them up all the same, then reverse
the middle one, and tape them together.
The "x"es are the POSITIVE terminals and the "o" 's are the NEGATIVE.
The bold ones are where you will later connect the wire leads.
The teminals connected in the drawing by dash lines are the ones you connect
together with paper clips.
With batteries tightly taped together (2 wraps max.), fasten the
two paper clips over the terminals (connected in the drawing
by the dashes ( --- )). The terminals marked in bold
are left unconnected for now. Be sure the clips touch only the terminals
in drawing. (taping them down will help keep them in line).
Assembling the eletrode leads:
Strip an inch of insulation from both ends of the 16" two wire lead.
(Two separate wires will work).
Cut 12" fine silver wire electrode in half (2 six inch pieces), make
a shepherd's crook in one end of each rod and wrap the exposed
end of each wire to it's own rod (or whatever silver implement you can
find). You can use either tape or rubber bands to tie it on.
No soldering is needed, just make sure the wire ends touch the ends of
the silver rod.
At other end of each wire, fasten two alligator clips. If you
don't have alligator clips, you can substitute paper clips or just wrap
the free ends of the wires to the battery pack terminals, using tape or
rubber bands to hold them on.
With one wire attached to each of the terminals (labeled in bold
above) , you are ready to make silver water.
Using the unit:
To make colloidal sliver, place electrodes (ideally) in steam distilled
water (glass container, tinted if storing for any length of time), and
fasten the other end of each wire to their respective terminals on the
battery pack. For quick stuff, add 3 or 4 grains of
salt and brew for about 5-10 minutes. For long stuff, heat
water (not so hot that you can't hold the jar), put in electrodes
for 40 minutes or so--without salt this time. ( In either case only the
silver rods should be in the water. You don't want colloidal copper or
aluminum.) If you don't see the clouds of silver sintering
off one of the rods, add two grains of salt and keep going. When
finished, disconnect from battery pack, clean rods with NON metallic cloth
or pad (Scotchbrite works), and store in a bag somewhere. If batteries
were scrounged from smoke alarms, now's the time to put them back.
What you do with this stuff is up to you. Someone may try to sell
you a "better" unit. It's your money.
