Thanks Guenter,

Why does the cone rise with the alternating current?   What vectors make it 
spin?

Hello Fred and James and the others,
one should not forget that in water one has always also OH- and H+ ions
(and with changing concentrations during the process) . Assume an Ag+
has been released from the anode, it may combine for a while with a OH-
forming AgOH and being neutral then. It will not be attracted back to
the electrode in the negative cycle. (Not totally true, see below).
Another Ag+ -Ion or a AgOH-molecule, or both can bind to it and thus may
form a larger cluster which is less mobile and will therefore also not
reach the electrode in the negative cycle. 
In addition, water dipoles will be attracted by the charged particle and
surrounds it by a water skin (Ivan often has emphasized this). The
particle stays positively charged, but its mobility is further reduced.

Now to the movement of neutral particles: 
If these particles are dipoles (positively charged at one end and
negatively at the other) they may be attracted by unhomogeneous (e.g.
cone shaped) electrical fields. This is the same mechanism which happens
at HV when the water molecules are attracted to the wire, suspended
above the water level.

Does this help? 
Gunter
