Charlie And The Great Glass Elevator

Look. It's a great deal of fun and Willy Wonka is hilarious, but a big whack of nothing happens in this book. They go up into space, do one thing, then come back down and proceed to first sincerely screw up and then, with complicated science fiction frippery, undo the screw up, the end.

They return to essentially where they start and I'm not entirely sure anyone learns a damn thing from any of it?

My kid loved it though, so here we are.
