This is a good video. I wish the camera was a little steadier at the start, but it improved as you went on, so keep improving that aspect. You're correct, videos really do help, I would have had trouble understanding your description of the process if I just read it -- you use words I don't recognize. Example, "magnetic stick" isn't the term I recognize for a stir bar. The production values are very good for an amateur video -- you showed a step, then you speed up playback so as to not waste our time, and your cut scenes of text were very good for saving us time as well. I'd like to see more of your videos. An example of spectrophotometer output would have been nice for wrapping up the video.
