Hi Kevin,  I believe Naturalamb is sold through many drug stores,
including Rite-Aid which is one of the biggie chains like Longs - at
least out here on the west coast.  Probably Longs has them too, but I
don't know.  Don't wrap the cathode tightly in the condom; in fact you
should use something non-reactive with lotsa holes like a plastic
hair-curler to space the skin away from the cathode.  The cathode should
not come into contact with it since the current concentration might
weaken or pierce the condom, (and you know what that could lead to!<g>)
Regarding pots; our local hardware and nursery and everything else store
has little ones, "two inch pots" and "three inch pots" I think they're
pretty common - not very tall, though, maybe2 1/2 " to 3" high for the
two inch.
Did you ever live in the southwest?  The "Olla" is a Big unglazed pot
for the drinking water of the house; the water very  slowly soaks out
through the microscopic pores and evaporates, keeping the Olla and its
water cool.  Doesn't use much water, either.  All of which has nothing
to do with CS, really . . . . .
To isolate the cathode just keep its area approximately equal to the
anode's - it doesn't have to be the same shape, - and arrange things so
all parts (or most) of anode and cathode are 'about' the same distance
from each other - no pointy projections toward each other, though.
I don't know if Ag+ particles or ions either can pass through clay pots;
I suspect not.  But the sheepgut - in condom form - is indeed safe.  I
just had to work that in, and it's true, too.
Another idea that might be possible is to run the generating container
vertically, with the silver anode at the bottom and the pot with cathode
inside immersed almost to the rim above it (and solution, don't forget
the DW and maybe a small shot of CS inside the pot!  Or Condom!) .
Take care,   Malcolm
