@sierrashark given that water is electrically conductive, has any excellent specific heat capacity and is transparent, you should be able to get optical ethernet, power and cooling via a single connection.
Then everything can be plumbing!
@Nixie I think it’s a delightful tradition to have stupid real-world objects being mysterious sci-fi widgets. I’d rather someone kitbash a physical set than green screen everything to death.
But also, I’m terrible at recognising these things until someone points them out, so maybe it’s just me.
