I wasn't sure whether to post this question in biology or physics.
I'm stumped on a couple experiments.
Here are the basic experiments. I have people wash their hands and dry them off and then hold onto the probes of a volt meter. To my surprise some people give a reading as high as .3Volts while others give 0 volts. Why is that?
The other experiment involves a radio frequency detector with an antenna. In open air it just scans and reads nothing but when I place the antenna about an inch away from a person the radio frequency detector often detects some frequencies while in other people it does not. The subjects said that they had no metal fillings or other metal placed in their bodies. What might cause that?
Thanks in advance for ideas.
