A 26 year old man decided to take a cup of instant coffee. The tragedy began.
He put in the microwave to heat up a cup with water only (something I had done before in several occasions).
I do not know exactly how long scheduled, but told me he just wanted the water to boil. When the time is up the oven went out, and he opened and took the cup from the oven ..
As he watched the cup, he realized that the water was not boiling, yet that's where the water jumped directly to your face. He dropped the cup of his hands after the water had jumped to his face, because the accumulated energy. Have sores all over your face 1st and 2nd degrees and it is very likely that the face is marked. Besides having lost the sight in his left eye partially. While we were in the hospital, the doctor who attended commented that these types of accidents were very common, and you should never put water only to heat in the microwave.
If we warm up water in this way (microwave), one should always put something in the water, eg a toothpick (same tooth) or one sachet of tea, but if we only heat the water, it is best to use the stove gas.
This is a physics teacher said about:
"Thank you for sending me the message warned me about the water in the microwave. Heard of several cases. This is caused by a phenomenon known as super heating."
It can happen at any time that the water is warming ..... especially if the tool they are using is new.
What happens is that the water heats up much faster than the bubbles begin to form. If the cup is new (very clean and smooth) , there is no graze or groove where the bubbles can go and can start the bubbling process in the water that higher than the boiling temperature (100 degrees).
What happens then is that a any slight shock or even contact with slightly cooler air can initiate sudden boiling that is almost explosive.
Please send this message to all your friends, can avoid a great deal of pain and suffering .. translated from Spanish
