I had a random desire to post another video, and this was the first one I found on my computer.

Some crystals of Potassium Permanganate (MW=158) on the left and Methylene Blue (MW=320) on the right. Time-lapse video w/ images taken every 30 seconds, but I don't remember how long this was in realtime. Probably a couple hours? Then I sped up the playback.
