Everywhere you turn, a machine is working away in the background, telling the time, powering your car or helping you to get clean.

We asked six-year-old Daniel Hart, of Stockwood, what he thought of the book.

He said: "I want to be an inventor when I am older. I would like to invent a submarine or a nappy changer for my mum and dad to help them change my little brother's nappies.

"Lots of this book is new to me. I like the page about submarines – I like underwater things because I love swimming."

His mother Maria said "Daniel is always wanting to invent things, he has a large imagination. I think the book is good – really colourful and the Disney characters engage children with it a bit more.

"The different sizes of text are good too. It is even the sort of book I could sit down and show my two-year-old son Matthew."

Next week, you can collect another book in the series, Reptiles and Amphibians.
