I think every child should read this book. What a way to get them interested in STEM and the world around us! My daughter and I loved all the chapters -- the chapter on fabrics, the history of paper, and how refrigerators were invented. Shruthi talks about how Albert Einstein even attempted to design an environmentally friendly fridge but gave up. This design is being revisited, by the way! The chapter on the history of crayons was great to read too, and we liked how it talked about the controversy of Crayola's 'skin' colored tone, which was light in color. We read the chapters on electromagnetism, zero and the decimal system. We came back from the book with our minds full of ideas!
