You can observe something like this in macroscale with lemon pips in tonic water. The pip sinks to the bottom of the glass, as it does so, bubbles of CO2 come out of solution and stick to the pip, ferrying it back up to the top. And on it goes!
- pantulis 3y ago> You can observe something like this in macroscale with lemon pips in tonic water. Why, that's interesting, I have never observed this. Do you think having previously added gin to the tonic water solution may have had something to do?
- jaggederest 3y agoThis 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.

- selimthegrim 3y agoHow about ten?
- plussed_reader 3y agoDon't forget one for control.
- pphysch 3y agoI will attempt to reproduce the results.
- tejtm 3y agothis may be a case where a sequential scan from low to high is indicated over a binary search of the gradient
- Someone 3y agoThat works with raisins, too.
