When I first started doing interactive, it was really hard to get folks up and participating. I've tweaked and tweaked and here is what works for me.As we're starting, I ask "how many have been to a friend's house for dinner" (everyone raises their hands). "And usually the first place you'll go is....(they answer the kitchen)...and usually one of the first things you say is....(they answer "what can I do to help"--most of the time anyway). So what we're going to do is just like that...a bunch of friends gathering and helping to make a meal" If I have someone who really resists participating, I'll have them read the recipe and keep us on track.Then, to make sure everyone gets a "chance" to participate, I'll have laid out the main tools I want to make sure we use and talk about and ask everyone to pick a tool they think looks interesting or they've always wanted to try. Then when the step that involves that tool comes up, it's their turn. So far, I haven't had any complaints about interactive shows and people are buying (or putting on their wish lists or hosting to get) the items they're trying. I'm ALWAYS using the Mandoline and DCB...they're some of my best booking tools.
