  • thumbs up if u saw the "fizz it up" cup!

  • so it makes the foam stay on top of my soda?

  • wait so the molar concentration of CO2 in the pressurized air is the same so the equilibrium doen't shift right? that would explain why the fizz keeping device I got didn't work, this one does seam long enough t potential blow bubbles into the soda but I'm not sure if that will have an effect on soda saturated with CO2

    but I would like one for my pneumatic gun hobby

  • Carbon Dioxide is 30x more soluble in water than oxygen. By what principle does pressure keep the carbon dioxide from mixing with the higher pressure air in the bottle?
