There is probably no better effect to do when someone comes up to you out of the blue and says "Do a
trick". I just love this. Also, they go through many different variations and there are a zillion
more. You can have a word change into another, you can show your hand blank and "grab" a card from
someone's thoughts, Write one card on your finger, show it as an incorrect revelation, and have it
change into the correct card, etc. So many options.
I will say that when I first got it and saw
the DVD for a few minutes, and tried it, I wasn't impressed. When I learned the technique and how
they have applied it, I thought this is just great.
If someone asks you to do magic, all you
need is your hand and a pen! Highly recommend it!
