Two interesting articles... http://www.skepdic.com/dowsing.html http://en.wikipedia.org/wiki/Dowsing One more: http://educate-yourself.org/dow/index.shtml The three most common dowsing tools are 1) the pendulum, 2) the "L" rod, and 3) the "Y" rod. There are other types of dowsing tools beyond these three, but these three are the ones most often used. 1) The pendulum is nothing more than some sort of weighted object hung from a thread, a string, a piece of fishing line, or a light chain. You can tie a paper clip to a short length of sewing thread and Voila, you have a pendulum. You could also tie a threaded nut to a length of light monofilament fishing line and you have yourself a dowsing pendulum. Most dowsers like to use something for a pendulum that's more fancy looking like a turned brass bob or a crystal pendant, but it's not necessary. There is nothing magical about the pendulum itself. It's merely an indicator tool, and nothing more. I will add, however, that certain pendulums (made of certain materials) can be more responsive than an ordinary pendulum (and therefore are preferred for that reason), but all pendulums will respond to your questions, regardless of what they are made of. 2) The "L" rod is usually a length of stiff wire shaped like the letter "L". Usually, we place tubing on the short leg of the "L" so it will rotate freely when we hold the L rod in our lightly clenched hands. The long leg of the "L" is held in a horizontal position out n front of us and it will swing to the left or right in response to the answers we are seeking.... .....If you contact the American Society of Dowsers (PO Box 24, Danville, VT 05828-0024) web site: http://www.dowsers.org/ Tel (802) 684-3417; E-Mail: ASD@dowsers.org), they will tell you the location of a Dowsers chapter that is nearest to you.
