hello everyone,
many of you know that this is a subject very dear to me. for this reason, I am taking the opportunity to share with you a beautiful laboratory adventure that I proposed to some of my students: the construction of the TUBOFONO (tube-phone), using exclusively (or almost) waste materials found in school environments.
just to be clear.... the PVC pipes are former containers for geographic maps that we found rummaging through the dusty and never explored storerooms of the school.

Is there a way to listen to it?

now I will try to make a recording. if it is sufficiently decent I will share it, ok?

There it is... a raw recording. The intonation isn't perfect, it needs to be refined (but we've done the math and, at least on paper, the precise measurements are there!)

It seems really interesting to me, could you indicate the diameters of the tubes and the lengths for each note? Thanks! Alessandro
