@SethGreene531 I thought someone would have this technique. How long does it take? I’ve always been too afraid of superboiling the water in the microwave ever since my grandma told me about that as a kid
@SethGreene531 mmmm nice 2.45 GHz excitation of the water molecules! Yum. But I wonder what other things microwaving water purely to make it boil does...
@assemblingaknob [b]Continue to use your microwave oven.[/b]
That above is someone repeating his Grandma's ignorance and someone else quoting equally nonsensical rubbish based on a cheapskate TV cartoon series. Were they taught no science at school?
A microwave oven's radiation is UHF radio (similar to radar), [i]not [/i]radioactive (ionising) radiation.
Its steel enclosure with a metal screen on the window is electrically earthed, and the door is interlocked to prevent use open; so unless damaged, none of the radiation can leak out and try to cook you as well.
Regulations vary by country but in some, microwave ovens used by way of trade have to have periodic tests to ensure they still meet both radiative and simple electrical safety.

You can [i]not[/i] "superboil" water. There is no such thing.
Pure water boils at a temperature affected [i]only[/i] by the containing pressure, which in a microwave oven, saucepan or kettle is that of the atmosphere in your home, so 100ºC at sea-level. Water in Denver at >2000m altitude, will boil at a slightly lower temperature than in San Francisco, down on the coast.
Though the boiling-point is increased by any solutes in it, such as sugar and salt in foods.
It [i]does not matter how you heat i[/i]t, However much extra energy you put into it, boiling water will not become any hotter: once it is boiling the additional heat simply keeps it evaporating at the [i]same[/i] temperature. It will just evaporate more rapidly.
That [i]superboil[/i] word might come from someone reading about [i]superheated steam [/i]and misunderstanding it. (That is [i]steam[/i] raised to a higher temperature than at which its [i]water [/i]was evaporated; used in, for example, power-stations; to increase the plant's overall energy efficiency.) In cooking terms, 'superheated' is meaningless, and the word 'superboil' is just nonsense anyway.
@assemblingaknob superheating is the term I came across after reading @ArishMell’s comment. Apparently, it’s much less common than the internet claims, but it is possible under the right conditions and you don’t want to stand directly over the cup/mug when interrupting the surface of the water if it’s been heated in the microwave for an [i]excessive[i] time.

@chocolateNcheese I had a friend who made his instant coffee with cold water and then heated it in the microwave. The problem with that is you are also heating the mug to be to hot to drink from.
