Nothing remotely to do with gardening
I have some L-shaped metal plant supports that interconnect.
While deciding where to use them, I thought:"They look a bit like dousing rods."
So I gave it a go.
They spread apart and cross over in various parts of the house and garden.
I tried to find a genuinely scientific reason for this on Google, but all l can find is hocus pocus , New Age stuff, exposure of charlatans etc.
Setting aside magic and special powers, why do they move?
