    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.

        I use my kettle 3 times before breakfast. So let’s call it 6 times a day assuming I tail off towards bed time. That’s 36 times a week assuming I spend 1 day away from home.

        So what has taken you 27 years to achieve, I achieve in 2yrs and 3 months. Or to put it another way - I have 12x as many chances to get just the right conditions to flash boil the skin on my hands off.

        American minds cannot comprehend the British commitment to a cuppa.
