Interesting information! Thanks for the heads-up.

The only time I boil water in the microwave is when I am cleaning it. I use a Pyrex 2 cup measure, pop it in for a couple minutes, then LET IT SIT for about a minute. The steam loosens any spatters and makes it easy to wipe down.

I will absolutely make sure I let it sit! no need to rush any cleaning, as far as I am concerned, LOL

I always make my tea and coffee in the microwave, but as was written, I put cold water into the cup, add my instant coffee then heat it for 1 minute 40 seconds. Making tea, I put the tea bag in the cup of cold water, heat it for 2 minutes. I have never had it boil up because there is something in the water.

I am a born again Christian and I love the Lord with all my heart. He has changed my life so I now live with more peace and contentment. I no longer desire to have what some of my friends have , but know God knows my needs and I am so grateful that He has given me my needs and not my wants. I enjoy writing my daily blog Bible Verse for each day. I enjoy spending time with God every day.
I enjoy Spark People and the ones I have become friends with. Thy have become an encouragement as I go al

I just read this post on the "Seniors 60+ - Fit For Life" team page and thought it was worth passing along. Something that makes sense to me once I read it but that I hadn't thought of before - very dangerous:

A 26-year old man 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 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 suddenly 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 a 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, (nothing metal).

General Electric's Response:

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

Here is what a local high school science teacher had to say on the matter: 'Thanks for the microwave warning. I have seen this happen before. It is caused by a phenomenon known as super heating. It can occur any time water is heated and will particularly occur if the vessel that the water is heated in is new, or when heating a small amount of water (less than half a cup).

What happens is that the water heats faster than the vapor bubbles can form. If the cup is very new, then it is unlikely to have small surface scratches inside it that provide a place for the bubbles to form. As the bubbles cannot form and release some of the heat that has built up, the liquid does not boil, and the liquid continues to heat up well past its boiling point.

What then usually happens is that the liquid is bumped or jarred, which is just enough of a shock to cause the bubbles to rapidly form and expel the hot liquid. The rapid formation of bubbles is also why a carbonated beverage spews when opened afterhaving been shaken.

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