A watched kettle never boils...
…so I’m not sure whether this see-through kettle in a shared workplace really did take forever to reach 100ºC. I was watching, and it took ages. I used the state-change staring time to remember a physics supervision from university, and how much I enjoyed learning about the sound of a kettle. I listened to the transition from a scratchy, higher pitched “cavitational crackle” to a mellifluous, quieter bubbling as the process advanced.
