This trick is nice and not difficult to do, especially the "easy" version. Unfortunately I think it
is not practical for a few reasons.
1. Must be performed seated and I almost always perform
2. It is not obvious how you get into the starting position, with the gimmick ready, in
front of the spectators. No hint about this problem in the video. All performance video clips begin
with the props already properly setup on the table
3. The props are not examinable
you can live with these limitations (I cannot), then you should consider learning this.
