I've got this from another site (sorry), but this is a worker! In addition to its awesome effect,
the beauty is that you can also hide some small things with it. In my case, I hide a coin with it
and make it vanished and reappearing from another place.
My daughter was dumbfounded, and it
has also passed my wife's really keen eyes, which happens not so often. Though I am just a beginner,
I am sure I can perform it in front of a lot of people.
