When the timer shut the oven off, he removed the cup from the microwave. As he looked into the cup, he noted that the water was not boiling, but instantly the water, in the cup, "blew up" into his face.
The cup remained intact until he threw it out of his hand
but all the water had flown out and into his face, due to the build
up of energy. His whole face was blistered and he had first and second
degree burns, to his face, which may leave scarring. He also may have
lost partial sight, in his left eye.
They can actually get superheated and not bubble at all. The 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 not heat any liquid for more than two minutes, per cup. After heating, let the cup stand in the microwave for thirty seconds before moving it or adding anything into it.
