If you've ever taken young kids fishing, you know they are really good at keeping you so busy you can't get much fishing done. So, this little helper might save you some time by letting you prep a bunch of hooks and lines for the inevitable snags.
I suggest not tying the hook part too tight, tie the part going to the pole with a few iterations of knots. That way you can easily slip a new hook/rig on as they get it snagged in every bloody thing in sight.
