Magical Knots Joker 
The performer shows a rope to the spectators.
He coils it up around his hand, ties a small magical knot on it which then makes four knots appear on the rope.
He unties the first knot, but to speed things up he coils the rope once more around his hand that becomes the magic knot again.Â
All the knots vanished!
After this more tricks can be performed with the rope and it can be handed out to the spectators to examine.
