@nicedragon Sounds like a great idea. We recently bought a big vacuum jug that gets filled up with boiling-ish water at the start of the day, so I can at least top up a cold half-cup of tea without recourse to the microwave. As a strategy it kind of works, but that damp Schrodinger mugs keep on materialising. Maybe the microwave has, in fact, caused a fracture in the space/time continuum.
