An explanation of paper chromatography in a movie, with voiceover. In this animation, the dyes don’t smear, so students can see what is meant to happen, rather than what really does.

Reaction mechanisms are beautiful dances, with the dancing atoms throwing out two (heterolytic ) or one (homolytic) arms out to their partner. Thus, I added a little beat to this reaction mechanism.
