You will get MUCH more out of the trick when you buy it. Believe me if you try to learn an effect from a tutorial then try to learn it from the artist on the DVD or book or even a PDF file you will realize why you should ALWAYS buy the effects.
Like I said, buy the effect instead of trying to learn it from a kid with a webcam. The artist who spent years perfecting his effect will give you much more insight than a 10 year old with rich parents and a computer. :D
I don't know how to feel about this right now... hmmm.... Also if you really want to learn the tricks... buy them. The people at learn magic tricks can't teach you how to do the effect like the artist who created it can.
