The Gypsy Thread by Quoc-Tien Tran

A thread is broken into small parts, they are rolled up together into a ball and then the thread is magically restored. 

But this time the pieces have different colors, so in the end they restore into an impossible multicolor thread without knots. Because the knots have diappeared under the very eyes of the audience as if the pieces of thread were melting together. A poetic an magical moment!
