I have to start this by saying I love this booklet!
Once you've read what Mark has put together you'll be able to read someone's mind about a film they’ve seen or a book they’ve read. There's another good one where you are able to correctly predict the change in their pocket and even the date on a coin.
I've seen Mark use these routines in front of real people and I look at these as more than 'effects' but secret weapons that you have just waiting to crush your audience.
