A conversation with a friend made me suddenly recall that when I was a kid in the early 80’s, we could occasionally hear a faint rendition of the major local AM station coming from the faucet of the kitchen sink. We lived just a mile or two from the broadcast antenna.
It was very faint and had a spooky sizzling quality, but it was unmistakable. Our wall-mounted telephone also picked it up, but more distinctly. I can understand the telephone noise reason, as there’s an amplifier and speaker. But a faucet? How?
In: Physics
Your faucet is attached to a pipe, likely made of copper. That long copper pipe is basically an antenna capable of picking up strong radio waves. A strong enough signal can induce small vibrations in the pipe, which are then amplified by the bowl shape of the sink.
