Videos - some entertaining clips I've encountered round the internets.

     - Are you a real man? Do you practically ooze testosterone??? Then using a straight razor may be for you. But seriously, let's just say there are good reasons nobody uses these things anymore, but nonetheless it's fun to buy one for $5 and learn how to shave the manly way. This is a very good tutorial for getting you started, and the same basic principles can even be applied to your gillete high-speed titanium 12-bladed stick shave to make it more pleasant and effective.

     - Good introduction to the art of lock-picking. Don't worry it's just a hobby.

http://filer.case.edu/dts8/thelastq.htm
     - A short story by Isaac Asimov (science fiction god) entitled "The Last Question", considered by himself to be his best work, and it only takes 10 minutes to read! I highly suggest it even if you're not into scifi.

http://www.bladeforums.com/forums/index.php
     - An endless wealth of information on man's oldest tool. Consider: every manmade object around you saw some kind of blade at some point in its production.

http://www.siteswap.net/applet.html
     - A cool little 3d juggling animation applet that takes "siteswap notation" as input. This notation actually symbolically describes juggling patterns, even very complex ones. The program is a good way to learn almost any kind of juggling routine, and is even just fun to play around with.

     - I could link hundreds of fascinating wikipedia articles, but this one to me is quite a gem. A parasitoid wasp that biochemically alters a host spider's behaviour to suit its purposes.

http://www.primitiveways.com/sapling_bow.html
     - An easy-to-follow how-to on making a flat bow, something like the Native Americans used. It isn't all that hard, and really puts you in touch with history.
