The magician presents three strings of the same length, which he ties together. He wraps them in his hand. A magic pass (indispensable, the magic pass!...), the rope is unrolled... yes THE rope, because now the knots have disappeared, and we only have one long rope!
Other possible presentation : You can also start with three strings of different lengths, which become three strings of the same length; then the three separate pieces "mend" to form one single string!
Easy to execute.
The fake equipment does all the work for you!
