This effect, when using a thin string or fine rope, has existed for centuries. Today it has been rescued by Ling-Fu, who uses a large diameter rope! This allows the effect to be performed in all kinds of shows and venues, from close-up magic, parlor, large stages, or even a track field!
In an impossible way, you will be able to transform 2 ropes into 1. You place this in the spectator's hands, and it seems unbelievable! In their owns hands, the rope magically turns into one, a great and original idea of Ling-Fu.
