I was a research intern at Oak Ridge National Lab. They put on several educational events for the interns. One event was a guy from the group doing forensic science to come in and talk about it. He talked about rate of decay of corpses and things like that.
Then he brought out dowsing sticks. Said something about the bones of buried bodies giving off magnetic fields that affect the sticks.
He then took a leg bone out of a trash bag, put it on the ground, and walked passed it holding the sticks. The sticks moved when he did it, but of course when anyone else in the room tried nothing happened.
Honestly, all the interns in the room were dead quiet. I think we were all really confused, thinking that maybe it was some sort of joke or hazing. Or maybe a test of some sort? It was really weird, but destroyed my regard for forensic "science".
