A 26-year old guy decided to have a cup
of coffee. He took a cup of water and put it in the microwave to heat it up
(something that he had done numerous times before).
I am not sure how long he set the timer for, but he told me he wanted
to bring the water to a boil. When the timer shut the oven off, he removed the
cup from the oven. 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 into his face due to the build up of energy. His whole
face is blistered and he has 1st and 2nd degree burns to his face, which may
leave scarring. He also may have lost partial sight in his left eye. While at
the hospital, the doctor who was attending to him stated that this is fairly
common occurrence and water (alone) should never be heated in a microwave oven.
If water is heated in this manner, something should be placed in the cup to
diffuse the energy such as: a wooden stir stick, tea bag, etc. It is however a
much safer choice to boil the water in a teakettle.

Thanks for contacting
us. I will be happy to assist you. The e-mail that you received is correct.
Micro waved water and other liquids do not always bubble when they reach the
boiling point. 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.
