Sounds like a great idea but to many thngs can go wrong.I personally have nevr had a incident turnin plugs but if i where to do it in a crowded place with the propensity of something goin wrong more than likely something would happen.Then there's the dust thing even wit a good system its gonna go everywhere the other vendors an the people with the mall might not like that.Perhaps a video or slide show would be better.I smell a marketing oppurtunity.I'm sure I've seen pen turning video's. U could probably make more money on a well made video than the plugs.
