Thanks to Manfred's explanation of how to use flash set with a rear-curtain synch, I was able to improve upon my previous attempt to give the impression that the cork is being removed from the tequila bottle. (In my first attempt I used no flash.) I also changed my grip on the cork thanks to Terri's suggestion.
It's not my favorite image of glass but it was helpful to get this technique down just in case I need it again.
