How to tie the Snap Bowline 

EducatedClimber here on youtube has an interesting format for videos on knot tying called "watch it until you get it". he just records himself tying, not once, but about a hundred times with different variations of the knot popping up about a dozen times each. I think he's on to something with it, it's a great way to learn a knot. Maybe not applicable to the snap bowline because this is especially for people who learn tying a knot difficult, but for any other knot i think it's an excellent format.
