Testing the Echo

I hopped onto the edge of the coffee table, eye to eye with a tall, empty ceramic mug. Perfect. I leaned right over the smooth rim, cleared my throat, and dropped a snappy little whistle straight inside. The sound echoed back instantly, deep and completely transformed! Naturally, I gave the porcelain rim a light tap with my claw just to measure the ring. A clear, sharp chime filled the quiet room. Who knew everyday dishware doubled as a sound stage?
