Stuff You Need to Know!
by John Farndon Author and Rob Beattie Author
When you turn on a light switch, type in your tablet, send a letter, take out the trash, or flush the toilet—what is actually happening behind the scenes to make all these things work? Kids need to know, and this book has straightforward, whimsically illustrated explanations that don't go into great depth but open the door for more curiosity and questions.
(This book may contain a small, black sharpie mark on the bottom edge, so that it can't be returned to a different wholesaler.)
