I've seen many magicians do this type effect over the years, but I was never able to figure it out.
Now Mark Mason has given us a powerful way to accomplish the magic without too much work involved.
The gimmicks included will confuse you completely until you watch the DVD. It all makes perfect
sense then. Mark does a great job teaching this and going into the setup. You will have some
pre-show work to do, and performing this more than once per night will require you to have several
boxes set up beforehand (it's not necessarily something you can reset between table-hopping). Still,
it's not impossible, and Mark even goes into the "card in mouth" routine he does in the demo video
in case you want to use it.
