For teachers and librarians

Everybody in the room has been held down by gravity every second of their life, and almost nobody has been told how it works. That is a very good place to start a conversation with a class.

We do the real thing first — why a hammer and a feather hit the ground together, why you genuinely do move the Earth when you jump, why you would be weightless at the centre of the planet rather than crushed. Then we do the invented thing, and the students work out for themselves which parts of the book could happen and which parts are a lie the author told on purpose.
