For children interested in how things work, [[The Human Machine by Richard Walker]] has proved a great hit with my six to ten year old grandchildren. If you're just gearing up for the school holidays then we can recommend [[101 Things You Wish You'd Invented and Some You Wish No One Had by Richard Horne and Tracey Turner]].
