Transformations. What are the usual things made of? Slevin B.

Do you know what an ordinary tree can turn into? To the mass of all: to the guitar, in a pencil, in a chair, in paper, in the fabric. A few centuries ago, both children and adults knew very well how a variety of things were created. People themselves prepared their food, and for this they grew plants and bred animals. They spun wool for clothes and sewed it. They made toys made of wood and fabric. When cars began to be used for production, people began to understand less and less in the device of what surrounded them. And also to do things from what it had never occurred to anyone from. For example, from oil, which can turn not only into fuel, but also into clothes, toys, buttons, food film. Thanks to this book, you step by step will pass all the stages of production of the set of all the necessary things. You will visit factories and factories, find out how oil and salt are produced, look at how they make food, clothes and many more that we use every day. Open the door to the magical world of transformations of simple materials into complex objects and you will be amazed at how many miracles are hidden everywhere!
