Don't ferrofluids break down in to the surrounding liquid over time? Or is that mitigated by treating the glass as was mentioned in the bluetooth speaker video from the article?
- opencl 3y agoFerrofluid has been used in certain high end speakers for quite a while, it can break down or dry out eventually but generally lasts well over a decade in that application. The glass treatment is just to prevent the ferrofluid from sticking.
- mr_sturd 3y agoThank you. I remember seeing someone had made a clock face using ferrofluids, and wanted to give something like that a go myself, but was put off hearing the information I was questioning.
- zamalek 3y agoThe smaller detail that really clinches it here is suspending the ferrofluid in another fluid. I have seen at least one of the clocks, and the ferrofluid doesn't behave nearly as nicely in air.
