If you want to know how concrete sets, ask a civil engineer. It was
an essential part of my education and training over 30 years ago, and,
I expect, of all civil engineers'.

Heck, even the Romans knew how it worked!
Perhaps, my point was that we don't need to know HOW it works :-)

... but that doesn't answer my criticism of dowsing does it!

As the above shows there *are* explanations of how concret works but
there *aren't* explanations of how dowsing works.

Oh there are, but none of them fit within the current worldview of science.
