It's not a good idea to dissect electrolytic capactiors. They have
nasty chemicals inside them.


Gee what is YOUR definition of "nasty chemicals" !!!
Sodium Borahydride maybe ?


From Wikipedia entry on Electrolytic capacitors:

Safety

The electrolyte is usually boric acid or sodium borate in aqueous
solution together with various sugars or ethylene glycol which are added
to retard evaporation.

*** Care should be taken to avoid ingestion of or eye contact with the
electrolyte, and any areas of the body where skin contact has occurred
should be washed in good time.

*** It is important to follow safe working practice and to use
appropriate protective equipment, notably gloves and safety glasses, when
working with the electrolyte.

*** Some very old tantalum electrolytics, often called "Wet-slug",
contain the more hazardous sulfuric acid, however most of these have
corroded away by now.
