home science filter: Why is my water is singing!

I just microwaved a mug of water. And after about a minute it started making a loud humming noise, like what happens when you run a wet finger around a champagne glass. It sounded like there were aliens landing in my microwave. What happened?

I microwaved the cup of water for about two minutes, dumped it out because there was something in it, refilled it and microwaved it for about a minute and a half when it started humming. I don't know if the cup being hot to start might be a clue. The noise was pretty loud and lasted for several seconds. Do you know why it would do this? My microwave has never made this sound before, I don't think it was a machine noise.
