Hey. Structured water don't exist in the sense you are using. No one ever submited a reliable evidence that it does. Of course water structure do exist and you can change it by introduction of polar or nonpolar substances or fields. But every structure change is driven only by the change of composition or conditions. If you do not change the composition then structure changes to "normal" in around 10^(-6) seconds after you revert the conditions. It is transcient in the sense. Crystals don't magically charge the water. Sorcery does not exist. Science is here to deal with the real world, not with your fantasies. And you know what? As Richard Dawkins told "Science works bitches". Magic do not. Cheers.
I got a degree in nuclear chemistry/radiochemistry.

Here is the real structure of water. Found in google.
