Toilet: How It Works
by David Macaulay
Toilets. We all use them everyday. But most children (and probably plenty of adults) don’t know how they work, or what happens after you flush. David Macauley’s book takes a look at that process. With a brief introduction to where the waste in your body comes from, Macauley explains what happens next. Using plenty of illustrations, he explains how a tank toilet disposes of waste. Next he follows where it goes, depending on whether you have a septic tank or are on the sewer line. An interesting look at something we all take for granted.
