Drinking The World's Highest Pressure Soda

Summary by Krater

The host explores what happens when root beer is pressurised up to 70 atmospheres in a custom pressure vessel using dry ice and heated into a supercritical fluid state, testing various dyes to see if they dissolve in supercritical carbon dioxide.

From the video

Answers: What happens when you pressurize root beer into a supercritical fluid?

• supercritical carbon dioxide
• pressure vessel construction
• phase diagrams
• supercritical fluid states
• dye solubility in supercritical CO2

What it concludes

• Carbon dioxide becomes a liquid when pressure is raised even at cold temperatures.
• Liquid and gas carbon dioxide become one single phase known as a supercritical fluid at around 73 atmospheres.
• Artificial fabric dye and ground vegetable powder do not dissolve in supercritical carbon dioxide.
