Guest guest Posted October 14, 2004 Report Share Posted October 14, 2004 Bill! All this talk of vibrations and excitement and fizzies! Getting heated, vibrate at a higher speed? Bubbles? More excited than its neighbors? Surface tension, an excitement point? HA! Where is our list headed? Tee hee. D. Who just couldn't resist...

Guest guest Posted October 14, 2004 Report Share Posted October 14, 2004 Bill Dunlap is 100% correct. Thanks Bill! Other folks call this " overheating " and when a catalyst is added (surface for the liquid H2O molecule to convert to gaseous H20) that's when it Fizzles. I am absolutely NOT worried about microwaving rinse water that will be long gone when I use the milk bottles. I think the whole society SHOULD BE very concerned about micro-waving other food substances. This is a real scare. That is what " ULTRA PASTEURIZED " means. Microwaved Milk. We all have to decide what we can & can't live with. Everything has something about it that is disconcerting. That's life.

There not any organic half n half in my area that isn't. I don't waste my precious Guernsey cream on my coffee (I make butter with it) So what's a person to do? - and don't tell me to quit the coffee ;o) BTW it is basically flavorless. Maybe I should go back to the local dairy non organic half n half? But I know way too much to do that! Rhonda who's starting to really get bummed out, as I thought that I was now eating only microwave free foods Quote Link to comment Share on other sites More sharing options...
