My favorite article ever in Physics Today: "The Urinary Drop Spectrometer"[0], and a followup note ("Urinary Drops Again") suggesting an audio version[1]. "Information from the external urine stream permits early, painless diagnosis of obstructions with an optical instrument developed by an interdisciplinary group." Japanese toilet models now have this kind of instrumentation, but the idea lay dormant for decades. I wonder if anyone has tried the audio version in the followup? Spectrometry on a stream of drops was hard in 1974, and relatively easy today. If I could avoid another kidney stone, I'd pee into almost anything.
