I spoke with my Dad last night, who has been a Civil Engineer for nearly 30 years. I brought up dowsing as it was in the news, expecting him to find it amusing. Instead, he said he’d been doing it since he started to find pipes and underground water! He gave me a very detailed explanation of how to do it, admitted he didn’t know how it worked, but it did.
I quite like it on the odd occasions that science doesn’t have an explanation for something. It’s got a bit too arrogant for my liking.
