What do you get when you mix a frizzy-haired, grandfatherly chemist with his younger, cackling, explosion-loving sidekick? The Periodic Table of Videos! Put together by a team at the University of Nottingham, this gargantuan effort of 118 short vids chronicles everything from Hydrogen (very explosive) to Oxygen (also very explosive) to Sodium (not explosive...until you add water!) on down the list all the way to Ununoctium, element 118, of which only three atoms have ever been observed. I bet if they get more, it will explode too.
With over a hundred videos to choose from, there are going to be plenty of highlights to choose from. Make sure you hit the explosive vids (as noted above), as well as Mercury and Helium — no bangs there, but with Hg, co-host Peter License talks about how he used to "play football (soccer) with it with our fingers back in school. We don't do that now because we care about our safety." Now that's responsible science!
