Hello, I've no personal experience of using distilled water as a
 dielectric, and I'd be surprised if anyone else has ... if you can keep 
the water pure it would be ok, but even tiny ammounts of
 contamination (any alkali, acid, salt etc.) would make the water a
 conductor. I think that your capacitor plates (Aluminium, Copper,
 whatever) would contaminate the water enough to destroy it's
 insulation properties. Personally I wouldn't bother trying - use oil.

bye ... Sulaiman
