Read before answering
Sound-path record: a second cup vibrates in a short taut-string model. The medium here is the solid string. A medium is material that carries vibrations. Sound can travel through gases, liquids and solids. These are supplied models, not instructions to go underwater or put an ear against equipment. Adults prepare any cup holes; string stays away from necks and paths.
