[TowerTalk] Divining rods and pyramids

[David Gilbert]

Either that is the most hilariously sarcastic post I have seen in quite 
a while (if so, kudos to you), or it is now apparent that I have been 
mysteriously transported to some weird alternative universe .... 
possibly Narnia or some place similar to it.   Anyone out there know how 
I can find the door in the back of the closet to get back home?

When there is an underground discontinuity made of water the Ls will tend to rotate to the center, making the 30 inch sides cross each other. Even if you rotate your wrists to the outside (right wrist going clockwise, opposite for left), making the rods to move upwards on an inclined plane, the rods will rotate to the center overcoming the pull of gravity for small inclinations. I could locate the positions of the corners of an old sewer system well in my backyard with this rods. Not a good place to put a tower, hihi
> More interestingly: I did the rods from a book about Pyramids ("The magical powers of the pyramid" is the translation of the spanish title). Using thin cardboard, I made a scaled version of the Gizah pyramids, about three inches high and a second one about three times that size.
> When the rods where moved at belly height over one of the pyramids sitting on the floor, the rods would rotate to the center very quick, ONLY IF the faces of the pyramid were aligned with the cardinal points the rods would move, if the faces were aligned with NE, SE, NW and SW, instead of N, S, E, W, the rods wouldn't move.
> To make the pyramid: Draw a circle on the cardboard. The radius of the circle multiplied by 1,0517 (the radius + 5.17%) is the square base's side lenght. With the base lenght draw four end to end chords on the circle and then draw lines between the ends of the chords and the circle center, this lines will be the edges of the pyramid that part from the square base corners and meet at the top (circle center). The chords are the four bottom sides of the faces. The four resulting triangles are the faces of your pyramid, no base needed. Then cut out the drawing and bend by the edges to form the pyramid, it is wise to leave an extra flip strip on one of the end faces to make the closing and gluing of the pyramid easier and stronger.
