Line Vanish by NOR

Almost any pen vanishes visually.
Pure sleight of hand.
Two versions are explained: a version performed on the table and on the hand.
The version on the table uses only one hand, but there are some requirements for the pen used.
On the hand version has almost no restrictions on the type of pen, but when performing a perfect vanish, there are conditions outside the pen.
Only this one technique is briefly described, so routine explanation is not included.
Explain only by subtitles.
