I read this book aloud in a library STEAM program for ages 5-8. I don't know that this book is anything special, but it did what I needed it to do in the program by acting as a simple introduction to pulleys and where they can be found.
OOPS! I didn't realize this was for children. I wanted to know how 1 person can pull X amount of weight on their own, but with multiple pulleys can multiply X.
