Firstly I think this book is too dumb because in this book there is a question like how cross a river and how to change a lightbulp, and the answer to those question is so dumb that you can’t do in realife (except if you are billionaire and has a money to buy a expensive stuff)
The worst question in this book is “How to cross the river” because all the answers to this question are useless and impossible like, build a machine that turns whole water into ice which is impossible for a normal boy. Most of the question in this book is about the situation we are unlikely to get into like how to land a plane.
Even though this book has useless questions l enjoyed this book because I didn’t know that you can do easy stuff in thousands of different ways. This book uses a UK metric measurement like fabric, mile and feet so I recommend using a computer to equalize the measurement if you live in Australia, US or somewhere else.
Overall I will give this book 3 out of 5 because I like this book but it is not as good as the book “What if”.
