Everyone knows where snot comes from but why's it there and what's it for? Dig deep (inside this book, of course!) and discover all the fantastic facts about breathing, blood and bogeys.

This irreverent pop-up guide is a fascinatingly fun read for any child. It's a fantastic companion for anyone studying science at Key Stage 1 & 2 - where children are taught about respiration and how blood circulates round the body.
