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.
