I found that the hydrogen tooltip said “heavier than or equal to air (moves down)” while the oxygen tooltip said “lighter than the air (moves up).” Was the tooltip inadvertently reversed or inadvertently reversed their density?

Very sure Oxygen in on itself is lighter than the Air, or whatever Air is made of. I should look up the actual kg/m³ Stats of Air.

Air is >70% nitrogen, which is slightly lighter than pure oxygen (28 g/mol for N2 and 32 g/mol for O2)

Though shouldn’t hydrogen also be lighter than air?

And fixed finally. Just took ages after Bear originally complained about it lol.
The Fluid System is based on “Numbers < 0 go up” “Numbers > 0 go down” and “0 is Air”
Ofcourse Air has 0.0012 g/cm³ so that aint gonna translate well…

Ha, that sounds like it was a load of fun to fix.
