Wow... that's scary. But I think that when the article talks about water being "rotated", it's talking about individual water atoms, whose rotation would be too small to see. I imagine that the waviness would actually be due to the change in refraction due to the microwave's uneven heating -- like the waviness seen in the air just above a hot road, or the faint ripples seen at the bottom of a pot of cold water, when you start to heat it on a stove.
