@DrLucyRogers got a random science q for you... When I run the hot tap, it starts cold. As the water gets hotter, the sound of it coming out changes; gets lower in pitch. It's so pronounced you can tell when it's hot by ear.
Why?

I only thought to ask coz she described herself as having a doctorate in bubbles! (And this is a fluids question. And acoustics, I suppose...probably some thermal dynamics? It *is* the hot tap after all!)

I would guess it's something to do with the % dissolved air. Moving hot water around sounds very different to transferring cold water.

Had that exact feeling, the price of taps limits the budget to single octave fluidic panpipes, but this has orchestral tones from a hack experience point of view!
