This is my little guy's (2 1/2 years) current FAVORITE book on the planet. It has detailed diagrams of everything from coffee percolators to forced-air furnaces and he can't get enough of it. He will flip to a page at random and say, "Mommy, read me all this information."
Amazing book! Instead of finding a few YouTube videos I’m able to fix things around the house just looking at the pictures in this book. It gives me more confidence that the thing I’m unscrewing can be unscrewed. I fixed my sink drain yesterday with it! I found this book outside for free but it’s one of the best repair books for learning a bit about everything.
