Why you should never microwave water?
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.

Why did butter explode in microwave?
The reason behind this butter explosion is that as butter warms up, the water separates from the milk fats. Once it reaches a specific temperature and overheats, the fat goes flying. Fortunately, there is a clean and foolproof way to melt butter.
Why should you not microwave butter?
The problem with microwaving butter is that the microwave can heat the butter unevenly, and tends to over-soften or even melt the butter in places. A New York Times article on butter in baking says, “Never use a microwave: it will melt it, even though it will look solid.
What causes a microwave to arc?

Nothing. Never start an empty microwave. Without food or a container to absorb the microwaves, the beams are bounced back to the magnetron. This could damage the machine and may even start a fire.
What happens if you microwave a grape?
When microwaved as one whole, a grape traps the microwaves in its center. When split in two and placed near each other, the trapped microwaves can hop from grape half to grape half, forming an electromagnetic field that ionizes the grape’s sodium and potassium ions. Then, fire!
Does opening a microwave while running damage the microwave?
It is just fine to open a microwave while it is running. It shuts off the magnetron immediately. If there was any leakage, you would feel physical pain as a result. It does not emit ionizing (cancer-causing) radiation.
