Why this word is great
HYDRAULOPHONE — [Noun] A musical instrument that produces sound through the movement of water rather than air. From hydraulic (relating to water or other liquids in motion) and -phone (denoting an instrument producing or involving sound). Unlike "hydrophone" (a microphone designed to detect sound underwater, not a musical instrument) or "aerophone" (which produces sound by vibrating air), a hydraulophone is a liquid aria, a song spun from the physics of flow. It is the finger interrupting a jet in a public fountain, sending ripples of pitch through the spray; the submerged keyboard of a poolside installation, where pressing a key releases a watery chord; the eerie, bubbling serenade of a stream forced through precisely drilled channels. Water, so often the element of silence, here finds its voice.
