Presentation ideas

I forgot to post this but I've been thinking ahead a lot because the presentation at the end of the semester for this project is very important as well. Last Wednesday I met with my mentor and he said "this might sound crazy" which of course alarmed me. His idea was that, during my presentation, I have a wheel and present it to the group panel to come up and try throwing. I think this idea is perfect because of the misconception of how "easy" wheel throwing is, and letting them try would open their eyes to it. Good idea? Bad? I think I'd demonstrate first, and then call one of them up.
