Animagic was asking for a functional stethoscope, so I made one based on Rampas' idea.
The prop itself consists separate parts and it is hard to explain how it works altogether.

I cannot say that the soft tube animation is a walk in the park, because it's very fragile. It takes a bit of a practice to animate it successfully and it looks weird until you hit Play.
But it is quite doable. I did not spend much time animating characters, but it's good enough to show the concept.
UPDATE 1/8/2022: Stethoscope is improved to be a bit more robust.
