Tuning Forks with Resonance Boxes

Using two tuning forks (of the same frequency), each mounted on their respective box, (box openings facing each other) strike one of the forks. If you stop that fork after a few seconds, you will hear the same tone coming from the other fork, set into vibration by the first one.
