The Quantum Boffin site was conceived as a way of swapping practical ideas and providing a series of videos that allow teachers to show demonstrations which, for whatever reason, they are unable to do themselves. Personally, I find the commentary (and/or music) that accompanies many videos extremely irritating and so when I put together my own videos I deliberately set out, where ever possible, to have no commentary - the commentary is the job of the teacher, not me: I'm merely providing the experiment. Remember: It is the experiment that is important, not the person doing it.
Interestingly, in this age of rich multimedia where pupils are constantly surrounded by things competing for their attention, I have found that pupils are no longer as fascinated with demonstrations as they were, say, just ten years ago. When I put on a video of a demonstration, on the other hand, pupil focus seems to improve significantly, even if it's a video of me doing something in the very classroom I'm teaching within. I am not advocating for an instant that we should stop doing demonstrations, but it's an interesting thing to think about.
