The inner workings of a home are laid out for kids in fun, retro illustrations jam-packed with the technology behind everyday life. How does flipping a switch on the wall make the lights come on? Where does the clean water that flows out of the faucet come from? What is used to keep a home warm? Travel beyond the walls and under the floors of a house to find out more about the electricity, water, and natural gas that make your home work -- and find out how you can do your part to save energy and preserve these resources.
