This is clearly self-promotional, but I thought some people here might enjoy a blog post about my new hobby of knot tying:

Or maybe one day you'll find yourself in a cave with stalactites hanging down, holding a rope in your hands, and then...
suddenly lava starts flowing into the chamber! Don't panic. Calmly "make fast" an icicle hitch to one of the stalactites, tie a loop on the other end, and you can then suspend yourself safely above the molten rock.
