Zipper

The Zipper is not a difficult trick at first glance. You start the trick with a Sleeper, then you get the yoyo into the so-called Undermount. You do this by swinging the yoyo and when it moves towards you, you hit the string with your finger and the yoyo beautifully turns around your finger and lands on the string. This is followed by a reverse Undermount, i.e. the same trick, but from the other side. And also on a different finger, this time the yoyo turns around the middle finger.

Now comes the hardest part. Gradually move your right hand around the yoyo and your left hand at the same time. Then you unroll the yoyo towards you one turn. Then you turn the yoyo once more, but in this case you need to put your right index finger in time so that the yoyo turns over it at the end. During this entire phase, it is important that this entire untangling is done with the left hand up and the right hand down, exactly as Robick does in the video.

Any other way might not be recognized as correct in a competition, so be careful. Finally, we put the right hand up and the left hand down and we are back in Undermount and we can repeat the Zipper endlessly.
