the PIRA DCS (demonstration classification scheme) to the web at:

To illustrate the utility of this resource, I extracted two references
which may be relevant to the "remanent charge on a dissected capacitor"
thread and one which supports Bill's suggestion to visualize the field
in a Kerr cell:

residual charge
Charge and discharge a Leyden
jar, Wait a few seconds and
discharge it again.

5C30.61
residual charge
After discharging a Leyden jar,
light a neon tube up to 100 times.
Also - show the polarity of
charge on the dielectric with a
triode.

Halowax oil is used between the
plates of a capacitor set between
crossed Polaroids Charge the
capacitor with an electrostatic
machine and the transmitted light
will vary.
