We hire entertainers at our haunts to provoke the people waiting in line. One of our the entertainers is a magician. He used a small carrying table that he could set up anywhere to perform. I saw a haunted table trick years ago that scared the hell out of people. It looked just like a regular table but when you place an object on it, it shook and sometimes this object feel from the table.
Well, I built one out of pine for our performer. Here is the video link. http://www.youtube.com/user/Flash3DLLC?feature=mhum
If you watch the video please rate and friend request.
I will have a "How-To" soon.
