Microwaved water - a MUST read






A 26-year old 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 inhis 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 tea kettle.

General Electric's (GE) response:

Thanks for contacting us. I will be happy to assist you.

The e-mail thatyou received is correct. 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.

The superheated liquid will bubble up out of the cup when it is moved or when somethinglike 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.

If you pass this on, you could very well save someone from a lot of pain and suffering.

(This post actually a mail sent to me by a friend ASHOK PANIGRAHI from ALL INDIA RADIO, CUTTACK with a request to forward it to as many persons as possible...so I published it here.)

पानी में लवण होने चाहिए . distilled वाटर को उबालना और खतरनाक है . माइक्रोवेव का उपयौग बहुत आम हो गया है खासकर खाना गर्म करने के लिए लेकिन इससे खाने के पोषण तत्व कम होते है.
