Re: Techniques for Demonstration
If you are doing a demo to recruit new people, It seems to work well for us to have a beginner's class after the demo and to invite spectators to take off their shoes and try it. Then we have some snacks aftewards to talk to people one-on-one.
If you can get spectators involved during the demo that could be good too. Smaller people throwing larger is good to show people they can do it. Whatever you do, it will be impressive to people. Don't take too much time because it's important to get people involved and they may lose their concentration and leave if it goes on too long.
