What is this trick????

It is a 4a trick and occurs at 1:32 in this vid. And is there a tutorial for this trick?

is it the one where he whips the string into the yoyo and it binds? its called an open string whip/bind thingy. or atleast thats what i call it.

Simple concept. Pop the yoyo off into the air, and whip the string into the gap of the yoyo. Once the string hits the gap, the string wraps around a couple of times, enough for you to bind. Really, I didnt need a tutorial for this. Just pop the yoyo in the air, and whip string right into the gap. BOOM, a bind is done.

loose return is the name
