I honestly don't know if this trick is any good or not. I simply cannot follow the video. David
has virtually no explanation (verbally), and visually he continues to go back and forth without
letting you know what he is doing. I know eventually I need to buckle down for a LONG evening
trying to understand and figure out what he is doing, and why, and what the trick actually is, and
what it looks like in presentation, etc. It is just a TOTALLY confusing video.
