Isn’t ferrofluid highly toxic if ingested? It’s basically motor oil all things considered, and this feels like the equivalent of putting asbestos in gas mask filters. As while the ferrofluid might work incredibly well and theoretically you won’t ingest any fluid, if any part of the design fails you’re now consuming a toxic substance.
