I was awake in bed pondering over a question. This is something that I am considering putting in my book. It will go something like this... One person will want to poison another. They will do this by a bottle of wine or champagne. The question part is this - Could a person push a needle through a cork, inject the poison and take the needle out without the wine/champagne losing any (or very little) of the fizz ie: not going flat.?
