I purchased this new and have kept it stored at home without using it. Why do paper airplanes fly? How can you make them fly far? Why does bread have holes? How are rainbows made? Let's make shadow puppets and play! Let's make bubbles with a plastic bottle! Through this book, children can find the answers to various questions and phenomena around them. As an effective way to spend time at home, you can create fun memories with your children while looking at this book.
