Wait, don't skip this one: the Periodic Table was probably the bane of your high school chemistry class. You could hardly figure out what the heck it was and it drove you crazy. This is an opportunity to fix that. Chemist Theodore Gray knew that, and he built it -- as an actual table depicting the elements. But this site takes it one better: click any element and not only get a description of what it is, but what it's good for. Lithium, for example: it's a metal light enough to float on water, but you don't want to do that because water makes it explode. But you can make great lightweight (and long life) batteries from it, and plenty more. Amaze your friends at parties with a bit of knowledge about what makes the world around you.
