This the same principle you use when boiling an egg in your microwave.Cover an egg with tin foil,
and smooth the foil so no edges or points are
sticking out (if you don't, you'll have fire works). Put the egg in a cup
of water, and nuke it. The heat from the water actually cooks the egg
because it is in a faraday cage (tin foil).

Hey, how did we get to cooking lessons on the PIClist?
