Hey
As some of you may have seen i have beeen doing an experiment measuring the permittivity of water in an attempt to calculate the refractive index.
This has produced some odd readings as my experiments concentrate in the static range of permittivity i should be seeing a permittivity of water of about 80.

An interesting thing happened the other day though when i was redoing the experiment with the capacitance plates outside a pyrex container filled with water my permittivity came out as about 4-5.
My question is do the plates carry the charge through the pyrex around the container or through the water.
It seems permittivty of pyrex is in this range and as far as i know does not vary as much with frequency unlike water.
It is quite hard to describe without a diagram but id like you guys oppinions on this.
