Not only does "Andy Field Magic" go about showing the effect in a professional manner, he does so in a personable and thorough demonstration. Agreed, the effect is not magic in essence, but does show off quite the slight of hand. I appreciated that lack of jargon in the demo; the performer visually made sure that you understood what he was doing step by step. It makes for an easier learning environment when you know exactly how the effect is achieved through a slower paced demo. He seems to be very adept at this. Very nicely accomplished, would very like to see more.
