This and your related comments are quite interesting. I like the Newtonian approach of feigning no hypotheses for phenomena like this. Any explanation is going to be necessarily speculative. What isn't speculative is whether or not the technique actually works which it appears to do. I have no doubt that an accomplished stage magician could pull off similar feats in any number of ways.
