Sorry for getting way off topic, but microwave
ovens don't heat things by vibrating something
like the water molecule. This is a common
misconception.
Commercial ovens operate at 2.45 GHz. The water
molecule has a vibrational mode up around 22 GHz.
Roughly ten times the frequency of a commercial
microwave oven and way off resonance.
Microwave ovens heat food by dielectric heating.
It just so happens that the Dk of water is anywhere
from 40 to 80. The Dk of something like vegetable
oil or milk is about 3. Thus the source for the
thinking that ovens vibrate water more than
anything else.
Now back to our regularly scheduled program ...
