There are numerous everyday items in people’s homes that most people don’t really understand.  For example, it seems unlikely that the average person could explain to you, in detail, how a garbage disposal works.  Or, as another example, a trash compactor.  Also, most houses have irrigation systems that people don’t completely understand, let alone the electricity that is running through their walls.  In other words, most people take for granted all of the inventions of the modern world that they use every single day.  Take, for instance, the water heater.  Most people don’t really understand this particular item, nor how to check if it is running properly.
