Performer displays a piece of white rope at his fingertips and ties a GENUINE
KNOT in the center. After which, he takes a black hanky and rubs
it against his palm in order to “blacken” it. When
the WHITE knot is gripped by the hand, it turns visibly
into BLACK! To finish, the magician unties the knot. A short BLACK
section makes effectively a part in the center of the white rope!
A revolutionary discovery plus the "NEW-ERA"
Knot conception allow this marvel!
