Ryan from Washington suggested this one. I was looking aver the site over the past couple of days and am impressed with the content. HowStuffWorks has been around since 1998 by an NC State professor as a hobby. It has since been sold, but the content has apparently gotten a lot better over the years. It started with just science and machines but has grown to encompass almost any topic. Here are some of the recent topics:
– Can water go bad?
– How does America’s Army work?
– How does a toilet work?
– How Hangovers work?
Basically if you want to know how something works, this is the place to go. There are quite a few of these sites popping up, but this one is so well organized and written by experts, not people who think they are experts but the real deal.
