"What is magic? Then there is the witches’ explanation, which comes in two forms, depending on the age of the witch. Older witches hardly put words to it at all, but may suspect in their hearts that the universe really doesn’t know what the hell is going on and consists of a zillion trillion billion possibilities, and could become any one of them if a trained mind rigid with quantum certainty was inserted in the crack and twisted; that, if you really had to make someone’s hat explode, all you needed to do was twist into that universe where a large number of hat molecules all decide at the same time to bounce off in different directions. Younger witches, on the other hand, talk about it all the time and believe it involves crystals, mystic forces, and dancing about without yer drawers on."
