Dowsing Rods and Water Witching
If we are going to discuss "structured water" we maybe should add this other garden-related topic of high controversy.
I have--no kidding--seen a metal and plastic dowsing rod in an industrial-tool supply catalog! It looked factory made. Who would have believed it? Presumably it was more for locating buried pipes and cables, not "underground streams." You might be astounded at the proportion of people who believe in these things.
