Do try this at home. Or do it at a wine bar and become the star of the bar. So you've served the last glass of wine and the bottle is empty. Or so you think! Because, my friend, there are always 32 drops in an empty bottle. Don't believe me? Try it. Believe it or not, they will flow quite fast at first - so pour slowly enough to count them. And then just keep that bottle tilted and, lo and behold, "voila" - yup, 32 drops in an empty bottle. You see, whether you knew it or not - you'll always have leftovers.
