Whirly bird

This is a looping trick in my buddie’s trick book and it’s like tangler but it is inside loops. If anyone can do this could you show me. This is also called wirlwinds

I do not have a video, but here is how to do a whirlwind. Both hands perform inside/outside loops while crossing. Must start with a criss cross inside loop with each hand and immediately start alternating to inside/outdise loops with each hand. Hope that helps!
