It took me a minute but I figured out the YouTube video is part of it, if you click on an element, you get a YouTube video of people showing the element in glass tubes and such. Awesome idea, absolutely horrid execution. On the left, between the top bar, the state of matter key, and the YouTube video, there is hardly any room to see the periodic table.
Is it just me or is everyone experiencing that the YouTube video is totally in the way of allowing one to look at this site? I can't even close the video window ("how to destroy a magnet") to actually learn what this post is all about.
