SUPERHEATED WATER Microwaved water and other liquids do not always bubble when they reach the boiling point. They can actually get superheated and not bubble at all. Superheated liquid will bubble up out of the cup when it is moved or when something like a spoon or tea bag is put into it. To prevent this from happening and causing injury, do ...
