How Things Work: Discover Secrets and Science Behind Bounce Houses, Hovercraft, Robotics, and Everything in Between (National Geographic Kids) Hardcover – Illustrated, October 25, 2016

My boys love this book! It had lots of new information for both my reads-everything-and-knows-it-all 9-year-old and my only-reads-really-well-presented-non-fiction-and-mostly-Captain Underpants 6-year-old. They’ve both read and re-read this several times, and I’ve picked it up and learned a few interesting things, too.

Very cool book, even I learned things. Got it for a 5 yro, he loves it and wants to do all the experiments. Some content is over his head still, but for the most part we were able to read all of it and he really enjoyed it including diagrams that further the explanations. I'd recommend if you have a kid who is really into science and non-fiction, but not for any younger than 5.

Love this book! My second grader is obsessed with learning new things and this book is right up his alley! Got it in about a week ago along with “5,000 facts about everything” and he stays reading them both!

This was supposed to be a Christmas gift for our 7 year old grandson in 2018. Other than taking 2 1/2 years to deliver (i.e. ordered 11-27-18) the book is good, interesting and appropriate for a 7 year old.

Wonderful gift for a young scientist wannabe

My nine year old grandson loves this book. It is so interesting and he loves sharing the facts he reads in it with his mom and uncle.

great hard back book for my son

I gave this book and a companion book (5,000 Awesome Facts (About Everything!) to my friends, 9 and 12 year-old brothers, and love both. Of course, I had to take a peek inside before wrapping the gifts, and I loved them, too. They were a big hit.
