The Indian Rope Trick by Ken de Courcy

Handbuch der Magie (German book) by Jochen Zmeck
Page 124 et seq.

Personal Comment: The version in the book is much easier and can be done with any card. But in that version no tearing/restoration happens. The version here was described to me by Jochen Zmeck himself years ago. I tried to do it justice. Does anybody know the original source? I'd like to read it.

Difficulty 3/5
