Im a bit torn on this one, firstly you should know that you will require another gimmick to be able
to use this trick and secondly this gimmick is not examinable (although they do provide a
non-gimmicked version to switch and hand out to your audience).
I would suggest that there
are better methods of apparently putting a coin in a bottle, but if the concept of using a cork
makes sense to you then it could be worth checking out!
