This book gives children the power of X-ray vision to see what’s inside things.

When a child holds a page up to the light, s/he can see through to the page behind: for example, when a child holds up a page showing a car, she can see the engine under the bonnet (printed on the reverse).

The book is divided into five sections: What’s inside your body?

; What’s inside machines?

; What’s inside the world of nature?

; What’s inside buildings?

; and Your turn!

, in which children draw their own pictures, putting a present inside the box, snacks inside the fridge, a person behind the door, birds in the tree, etc.
