Your morning routine most likely starts out the same as everyone else's - make the coffee and get the paper (or check the news online along with your email if you're more high-tech). But what exactly happens after adding the coffee and water into your coffee maker? Coffee machines are no great mystery, but they're still an unknown for many people.
