This might sound humorous, but in all seriousness, it is a perfect chance to do some interesting armchair science with a gin and tonic in your hand. Try various lemon seeds, a gradient of tonic-to-gin ratios, maybe a control with water and/or plain soda, measure the oscillation rate (or lack thereof). Break out the statistics and see if there's correlation with the percentage, and whether it's significant and how large the effect size is. Write it up and publish it on arxiv for bonus points.
