I don't know if this is intended or not, but if you use pointed dripstone below a Purple Soda puddle, the particles are water droplets and as far as I can tell they don't renew cauldrons either. I was hoping this would be a thing for the sake of renewability, but it's understandable if that's not a worthwhile feature.

Dripstone mechanic about the 2 fluid isn't present in the mod, I'm wanting to contribute and commit it once I get how to do it... eventually... But for sure I want this feature too.
Somehow the purple soda isn't a water type fluid, so I wonder why It make water, a lot of thing to learn here.
