The phrase "who died from black ink" does not point to a specific individual or widely known incident involving death directly attributed to black ink. Black ink, used for writing or printing, is generally not hazardous under typical usage conditions. However, if referring to tattoos, there have been rare cases of complications leading to severe health issues, but these are typically related to allergic reactions or infections from the tattoo process, not the ink itself. In history, there have been instances where ingestion or misuse of certain inks has led to poisoning, but these are isolated incidents and not common enough to identify a specific pattern or individual case. If the context is broader or metaphorical, specifying the scenario might help pinpoint a more accurate response.

Glo Bug yarn, known for its vibrant colors and glow-in-the-dark properties, generally does not float in water. Its ability to float or sink depends on its density compared to water. Most yarns, including Glo Bug, have a density higher than water, causing them to sink. However, the specific composition of Glo Bug yarn could affect this; if it's hollow or contains air pockets, it might have a lower density and float. Testing a small swatch in water is the best way to determine its buoyancy. If you need it to float for a project, consider adding a floatation device or coating it with a material that increases buoyancy.

To list services in Yarn, which generally refers to managing application packages in the context of Node.js and not direct service management, you can use commands related to the packages and scripts defined in your `package.json`. Services in the typical "service management" frame don't apply to Yarn directly. However, if you're interested in viewing scripts that can be executed which might be akin to service actions, you can utilize the `yarn run` command. Running `yarn run` alone will list available scripts defined in your project's `package.json` file. This is useful for understanding what tasks, such as starting, building, or testing your application, you can perform with Yarn in the context of your project. Remember, each script in your `package.json` can be executed using `yarn run ` to perform specific package tasks or services you've defined for your project.
