I took a flat horn and cut a long V-shaped beak for a pour spout. I filed the beak to hold the ball near the tip of the beak. When "tuned" with a file, it will hold a ball in the beak and still allow you to pull out one ball at a time. When you remove one ball, another drops to take its place. No stopper is needed.
I hang it with the beak down. The last ball horn I made will hold enough for a woodswalk. When I get back home, I'll post a pic. It's not PC, but it is handy.
