I haven't 'popped a cap' for a long time. Just bought a 6-pack that had the old caps. Can't get too cerebral about bottle caps. But they're neat! Never noticed before how nicely they're shaped ... and contrasting. The smooth crown with the jagged skirt. The light shade of color on crown and sharp shadows of the skirt. And they pull off the bottle top so smoothly. It's a better way. It beats the harsh feel of the omnipresent twist-top. But society won't be returning any time soon. So I'll just sketch'm.
