If you are interested in doing escapes I would highly suggest that you think about purchasing the Escapology DVD set. It is about $100 but check it out
here and read the product description...
Also, I believe that you will find material for escaping from a standard hospital straight jacket in the book, "All the Secrets of Magic Revealed: The Tricks and Illusions of the World's Greatest Magicians." There are two major benefits to doing it this way: 1) you don't have to wory about audience examination! 2) You will save a HUGE amount of money!!!
