This is another practice video I filmed a while ago for the Kozlowski Bill Switch. The finesses I wanted to perfect included keeping the bill in full view at all times while also showing my palms empty throughout as many stages of the change as possible. Jay Sankey offers a wide array of applications for this technique throughout his work; I believe I learned the original handling from The Magic of Michael Ammar.
For me personally, this was the type of effect I always enjoyed in practice but never really executed much in performance. I always wanted to do more this as a full showpiece rather than a quick trick, but never really studied or developed anything I could commit to. After a performer changes a single into a $100, where else can he possibly go to top that? If anyone else actually uses the Kozlowski Bill Switch, I'd love to session through some alternate ideas for it.
Another worthwhile conversation: is this technique obsolete now? Over the years, various new and uber-visual versions and handlings have been published and released. Is there appeal or logic to seeing a magician fold a bill into such a tiny packet only to change into a different denomination upon unfolding it? To me, it sometimes seems like a very indirect means to an end, but it's a classic so magicians forgive its shortcoming(s).
What are pros and cons about this in comparison to similar effects? I pose this question to encourage members to think critically about the material they perform, themselves.
