This doesn't stand on its own from what experience I have with it. I use an "influence" story line
and I added this with a few other effects all done under the guise of language pattern influence and
that helped the strength of this effect. It can play out any way, but then you have to change the
part of; do I read the prediction, do I have them read it...... Still works and impresses, but
that's why I say good, not great. The gimmick can stick and then needs to be worked free as well,
which is doable under working conditions but then you are left with that unnatural feel when you
pull it off the key chain, tap it on the table, then subtly try to set the prediction before reading
it. I have found it to not be 100% reliable.
