Just a question

Do any of you know a trick that makes a knot in middle of the string. And that knot can be easily undone with a simple action? Cuz I found one…

What should I call it? It makes this ribbon thing in the middle, and if you give it some slack it becomes undone…

Yep. I’ve got my own trick I made which creates an intentional knot that can be undone just by pulling the string.

Yeah I get that happening too when I’m trying some tricks. It’s actually pretty well known as the “magic knot”
