Its this simple
you vanish a pen WHILE THE SPECTATOR HOLDS IT.
Doing magic with pens has built-in appeal since everyone carries them you can borrow them anywhere and they are uniformly recognized. How AMAZING it is then when you can take a pen and wrap it in a napkin. The spectator holds the napkin with the pen VISIBLY dangling beneath. You clap your hands together and...instantly...the pen disappears. This is a practical astounding illusion with the simplest of objects.
