Boiling water won't explode. Water that has had all the oxygen, which allows it to make bubbles (boil), usually by heating, forgetting and reheating, can be superheated. That's the stuff that can erupt when you add something, stick a spoon in it, or sometimes just moving it. Superheated water, is more like hot oil... very dangerous.
