The source and mechanism of a whistling kettle has never been fully described scientifically; acknowledging the vibrations made by the build-up of steam escaping through two metal spout plates is about as far as the explanation went. That wasn’t enough for engineers who, through a series of experiments, have produced the world's first accurate model of the whistling mechanism inside the classic stovetop kettle.
