Yes, working in a school, there's no way that you'd ever have heard that one before

First of all - distilled water won't be enough, as if it is in contact with air it becomes saturated with carbon dioxide and becomes acidic - which means it contains ions. What you will need is the ultra pure water (sometimes called 18MΩ water), and the experiment has to be done in the inert atmosphere. Working with ultra pure water is quite difficult, as it dissolves everything and becomes very easily contaminated; preparation and transport are an art it itself.

The idea is that hydrogen bonds cause molecules to be grouped together. So groups of molecules would react to the electric field instead of individual molecules, and this would amplify the effect.

Bugger!!

OK.

I'm back in school in a couple of weeks. I can try the experiment using titration burettes and trying regular tap water, salt solution and distilled water.

We'll get to the bottom of this!!

Some interesting looking refs in post# 8 there

when you get done with that, perhaps you could dunk a few ping-pong balls and steel balls?
