Web Site Tells You How (Almost) Anything Works

Do the engines of all automobiles have spark plugs?
How does a coffee maker turn hot water and some mashed up beans into a morning elixir?
What pipes carry water from the reservoir or tower to your home?
How does a pawn shop make money?

You probably wouldn't think about all those questions on one given day. But whenever they come up, there's a Web site that can explain -- in detail -- what makes things go.

HowStuffWorks.com provides background on what makes our world go. It covers everything from mechanical wonders to financial systems to software and culture.

Most of the articles also contained detailed graphics and background on the underlying technologies.

Of course, there's also a business aspect; once you learn how a digital camera works and what you need, there are shopping links to find the one you want.

The other day, I read something that indicated diesel engines don't have spark plugs. HowStuffWorks explained why they don't need them (air in the cylinder is compressed and heated before fuel is injected), and it can probably answer any question that's been puzzling you.
