When demonstrations go wrong: video evidence

I mentioned the other day that I gave a talk at TEDx Teddington, and video evidence has now emerged. Happily the 16 minute movie has been gracefully and mercifully edited so that several minutes (which felt like hours!) of faffing around on stage has been lost.

Seeing it now I feel that my first conclusions were right

  • Live demonstrations trump PowerPoint every time: even  when they go wrong the audience enjoy them!
  • But a few sparse PowerPoint slides can also communicate volumes.

The whole business of communicating on stage is subtle and that some knowledge of ‘stagecraft’ is essential and this is not my strong point. I feel this particular talk would have been better if I had had a chance to do it just once before hand!
