While out in Australia, I heard that microwave ovens are not good. One article seems to be saying a lot of extraneous material (never a good thing in a paper) though does seem on the face of things to have some evidence. Why believe the internet, though?

However, some of the 'damage' listed is possibly just as likely with conventional cooking.

One possible experiment is to plant some seeds and water them with tap water and microwaved water. So the design of the experiment would be:

3 pots - one watered with tap water, one with cooled microwaved water and one with kettle boiled water, also cooled. Time to set up some things :)

oh bugger, the other PC has broke.
