Microwave ovens shoot tiny waves into the liquid at random locations, causing the water molecules at those points to vibrate rapidly. If the water isn’t heated for long enough, the result is isolated pockets of very hot or boiling water amid a larger body of water that’s cooler.
Is it safe to drink microwave heated water?

Why you should never microwave water?

What happens if you microwave nothing?
What happens if you start the microwave oven with nothing inside? The magnetron creates microwaves that travel into the cooking chamber and should be absorbed there. If there is no food (or rather no water-containing food), those microwaves will not be absorbed and will eventually find their way back to the magnetron.
How long does water need to boil to be clean?
Boil water, if you do not have bottled water. Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015).

What is the most efficient way to boil water?
An electric teakettle is about 80 percent efficient, although again this varies from kettle to kettle. Electric kettles are generally very well insulated, and the heating coils sit directly in the water, so less heat is lost to the air. An induction stove or hot plate is about 85 percent efficient.

Can a dirty microwave make you sick?
Dirty microwaves not only pose a health risk with bacteria, but they can also lead to other problems. When food particles build up from spills, there is also a chance of them catching on fire as they are warmed each time you use the microwave to heat up something new.
