I am reading this a few inventions at a time with my 9 year old son. He is really enjoying the descriptions of how different inventions came to be. There are goofy illustrations with captions that are relevant & funny. This is a great way to inspire a kid.
My son and I like this book very much. I highly recommend it for an elementary or older student who's interested in the history of how inventions have come about. The only issue I have with it is that the print is very small, as are the pictures. I would have liked to have seen a larger format and print.
