See Inside Inventions

A big bright book with robust pages. Familiar objects, from domestic to industrial, are described on every page and then you lift the flap to find out how they work. So, look inside the piano to see the hammer action, lift the flap on the loo to see how ballcocks work. Check out zips and ballpoint pens. Large machines, like excavators, have more than one flap and a lot of information is packed into small spaces. A book to talk about and maybe follow up on the related website.
