How to determine the density of copper?
You can find a sample of copper’s density by first weighing it. This will give you the sample’s mass. Then, measure the sample’s dimensions, in order to determine its volume. Finally, divide the copper sample’s mass by its volume, and you will determine the density of the copper.

How copper dowsing rods work?
The dowsing rods do indeed move, but not in response to anything underground. They are simply responding to the random movements of the person holding the rods. The rods are typically held in a position of unstable equilibrium, so that a small movement gets amplified into a big movement.
