I love this book – such a clever idea.
I went out and bought one for the boys (although taking pictures of them using it is impossible because they were using a light under a blanket and fidgeting all over the place!) to have a look at and I have to say I was a bit skeptical about whether it would work or not.
But it did and it was so cool! Basically if book works on the same principle as that super fun invisible ink most of us will have played with as kids. The pictures are printed and when you shine a light on them the pictures change as if by magic!
The boys think this is hilarious and so much fun – Roo especially.
You can order a copy of the book from amazon here.
