I'd rather have a kettle anyways, less dangerous and faster. And it can also be very pretty.

Oh yes I am looking at you Fellow Stagg.

I don't think anybody seriously thinks that hot H2O can have a different formulation. What, are we postulating the existence of isotopes for molecules now?

Yeah, but it would taste nasty because my microwave’s minging.

Chemically yes, physically no. Microwaved water is more buoyant because it has a heat gradient and rarely boils properly. It tends to get superheated and explode rather than boiling.

This is why tea bags float on top of microwaved water but not boiled water.

Tea bags float in my kettle heated water as well. And for the 27 years I lived without a kettle and microwaved my water (maybe 2-3 times a week) I have never even once seen water get superheated and explode.

This. In the microwave, water is heated from top and sides.

In a kettle, it is heated from the bottom. With warm water rising to the top and cold water sinking to the bottom, the water will circulate to evenly distribute heat. This is the main benefit of the kettle.

I thought nearly any trace of minerals essentially reduced the likelihood of superheating down to near zero?
