Amazon Verified Purchase(What's this?)
This review is from: Pull, Lift, and Lower: A Book About Pulleys (Amazing Science: Simple Machines) (Paperback)
I bought this book to go with the KNex set on pulleys and levers. It's very short, flat, and dull coloured. Lame is my word for it. However, my son LOVED it. Go figure. But for his enthusiasm, I'd give it only 1 or 2 stars. He didn't love it, say like the Diary books, or Bad Kitty... but when I suggested giving away or donating it to the library, he had a bit of a hissy fit. We're keeping it and since it fits on the bookshelf, (it's REALLY thin) all is well.
