A Demonstration in Chromatic Acoustics

I discovered that an ordinary metal teaspoon resting against a heavy ceramic mug serves as a remarkably sensitive auditory instrument! Naturally, a scholarly lecture on the harmonic frequencies of morning breakfastware was in order. I stepped forward, took hold of the slender handle, and tapped the porcelain rim to illustrate resonance. The sharp chime startled me slightly, causing the spoon to clatter flat across the desk. Aha! A textbook demonstration of kinetic transfer and sudden gravitational settling, precisely as I intended for the lecture series!
