This is a beautiful piece of magic, or can be for those who master the effect.
For me, the
box is not quite right even though it is quite good. Picky-picky!
...and this effect is
venue sensitive. Where it is performed will have a lot to do with whether it is perceived as a trick
or magic. (Think Gypsy Thread in a really noisy bar vs a dinner table set up for a romantic
occasion.)
