So, I'm having to do a presentation at a conference next week, and I don't have time to do the demo I wanted. (Also, I don't want to have to take equipment on the road.) I'm wondering if a video is as good as a live experiment. For example, does the video here grab you. It grabs me, but I've done a similar experiment for my students live, and I watched the impact. I can't imagine the video having the same impact.
