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 he 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 buildup 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 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. It is however a much safer choice to boil the water in a tea < < kettle. < < Please pass this information on to friends and family. < < Here is what our local 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 anytime water is heated < and < will particularly occur if the vessel that the water is heated 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 after having been shaken." < < If you pass this on ... you could very well save someone from a lot of < pain < and suffering. < < < General Electric's response: < < Thanks for contacting us, Mr. Williams. 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 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. < < I hope this helps. Should you need any further assistance, please contact us.
