The snap bowline - around your waist and a tree
The snap bowline is a quick way of tying a bowline, by passing the free end through a slipknot.

It's good practice to backup the bowline if it's used in any climbing or life support situation.
This is typically done with an overhand knot or slightly more secure, a barrel knot.
Both methods are shown.

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.
