Microwave ovens, previously believed to be the height of kitchen gadgetry technology, are actually powered by pure magic. They are designed and manufactured by a coven of White Witches, who perpetuate the myth that the ovens use electro-magnetic radiation to cook food because they know that the public perception of so-called 'advanced technology' sells products, while magic tends only to inspire laughter in the average consumer. It is for this reason that microwave ovens carry warnings not to peer inside the 'machinery': far from being dangerous sources of radioactivity, there is actually nothing there!
