»In which we put a cork in it

Design Within Reach wonder what you might do with a champagne stopper -- cork, foil, metal cap, and wire.
I had a bushel of corks (all natural! no synthetics!) saved up from a few years' wine and whiskey; they went to Craigslist and disappeared. I thought of various things to do with them (add a pin and a piece of paper, and you have little boats! stick 'em to a piece of wood and make a bulletin board! throw them around the floor and watch the cat play with 'em!), but figured that someone else could make good use of my bibulous tendencies.
