Good to Know.
Well, that's apparently a bad, bad idea, I found out (see the link below for why). When the microwave beeped, I opened the door, reached my hand in to grab the mug, and all hell broke loose. The water literally exploded all over the place. I jumped back, I was totally spooked. It just was there, then it exploded.
I thought this was weird, but still too shocked to go into safety mode and ditch the tea-making project for the night. So, I put the tea down on the counter, and droped the tea bag in, and the MF'r exploded again!
At this point, I'm so freaked out, all I can do is come up with crazy conclusions like the water is tainted, the mug is tainted, something having to do with Gremlins. Dah. Freaked. Out. Go to the Google.
Couldn't believe that my search string actually nailed it on the first attempt ("boiling water weird microwave"), but weirder things have happened (see above). Result #2 yielded the answer…
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 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.
Ok. Won't do that again. I think my Dad is an old hand at Microwaving water, best send this post his way. I actually made out pretty well tonight. I managed not to burn my face off, and I learned a little science in the process.
