The simple facts are these: 1. There is no evidence, except in special cases of mental disability, that some young babies are born creative and inventive, and others not. 2. There is evidence that all children love to interact with variables, such as materials and shapes; smells and other physical phenomena, such as electricity, magnetism and gravity; media such as gases and fluids; sounds, music, motion; chemical interactions, cooking and fire; and other humans, and animals, plants, words, concepts and ideas. With all these things all children love to play, experiment discover and invent and have fun. All these things have one thing in common, which is variables or 'loose parts'. The theory of loose parts says, quite simply, the following: “In any environment, both the degree of inventiveness and creativity, and the possibility of discovery, are directly proportional to the number and kind of variables in it. “
