Somehow the last few paragraphs also got deleted.

THE VALUE OF THE EXPERIMENT

In addition to having the sun shadow deflection data you now collecting both tilt and rotation data. And the more data such as those that you can report, the easier it will be for researchers to determine exactly what it is that you are measuring.

Additionally, if you can show that the new tilt and rotation data can also be used to help forecast earthquakes then it makes your procedure that much more powerful. This additional feature would be very inexpensive for people to use in addition to the sun shadow deflection measurements. And those tilt and rotation data would still be available to people when the skies are overcast.

AIR MOVEMENT PROBLEM

If air movement causes the bar to swing back and forth too much then it could be enclosed in something like long cardboard gift wrapping paper tubes which would also be fastened to the wall. The tube material should not be magnetic, probably should not conduct electricity, and should not easily build a static charge. I believe that paper and cardboard are safe. A plastic tube might build a static charge.
