Vanishing Pen
Hi
I'm not familiar with this trick, so was wanting some info. I'm assuming there is a pen/gimmick and a regular pen. So can the actual pen/gimmick be examined beforehand or does a switch need to take place before the vanish, from regular to gimmick?
Also what is required to ditch the gimmick after it is vanished? I would think just tossing the napkin or bag away afterward would have people wanting to examine everything.
thank
