@markowenmartin @Shuyin_ben Here's dropping in water (left) vs some vinegar w/ a bit of citric acid that's had some rusty wire sitting in it (right). (The original glowy liquid here is filtered from a mix of the bacteria in water, so no bacteria theoretically just whatever they're secreting.) I'm going to try to document this better and share a video or post about it soon, got lots more growing 😁
