Dumb advertisement near me had a sign up about their “sparkling pool” which got me thinking…what would it be like to swim in carbonation?
I think you would float better? Probably? Would it hurt more? Would all the released carbon dioxide in the vicinity of the pool be a problem?


I’m pretty sure you would die because the CO2 doesn’t stay dissolved. It would be highly concentrated near the surface and would displace the O2 so when you tried to take a breath near the surface you’d not get enough O2 and would eventually asphyxiate. Just a guess though.
A normal pool probably isn’t big enough (or volcano adjacent, hopefully) to be comparable, but check out https://en.wikipedia.org/wiki/Limnic_eruption for some worst-case scenarios.
Wow! Ok this was really cool to read about. Thanks!
Definitely. Anytime you’re fermenting in an open vessel, the CO2 builds up and pushes air out. If you stick your face below the lip of the vessel, and breathe in, the tingles get ya.
The scary thing would be nitrogen dissolved in the water. Apparent nitrogen would do the same thing but it doesn’t cause the same starving for air result. You’d just pass out and drown. Although this is also just a guess.
It’s correct. The feeling of running out of air comes from the buildup of CO2, not the lack of 02.
Nitrogen and carbon monoxide just take the place of oxygen in your blood, so you drift off to sleep and never wake up.
