i should say that after i read the first book, i thought "wtf it is! it is trash". but one of my
friend, who has been a mentalist for many years, told me that i should read the second book, and it
will reverse my opinion. finally, i find he is right. i used the double facer and double backer
routine as the opener of a small scale show. the iforce version, which is my favorite, fooled dozens
of my friends, and they thought that looks like real magic. i think at the beginning, the reason why
i thought the effect was rubbish was because of i didn't follow the scrip written on the book. so,
buy it, and follow the instructure step by step, you will be amazed.
