Interesting seeing the first one, it was quick leap to see that the two open points needed to form a cross on each other in order for there to be enough space for them to unlink. The later ones are much more complicated. I doubt I would have made that realisation without seeing the simplest form first.
I skip some of the solving Because I don’t want to make the video too long The audience will get bored But if you really want to see the full solving I can make another video next time❤❤
