That the rods cross in response to hand movement is certain. To prove
otherwise, one could build a jig that holds the vertical rod ends parallel
& use it to dowse with. If they did cross, it would prove that hand
movement wasn't necessary. If someone tries this, please keep us posted.

That is an interesting proposal. I have heard, and mentioned in the video
that some people cannot develop the light holding pressure required, so use
a couple of empty Tabasco bottles. One would then cut the short end of the
L long enough to rest on the bottom of the bottle. I have seen these for
sale with telescoping sections, looking like a very small telescopic radio
antenna on the old transistor radios.

I will do what you ask, and try to get my photography better, too. I shall
use a jig made out of wood, and the two Tabasco bottle idea thing, too. The
way I do it is just the simplest, but I have always wanted to try the little
bottles, too.

I shall keep you all posted.
