Why Does Soda Fizz So Much When You Shake It? | RapidSmartFacts

Shake a soda bottle, open it, and it can explode with foam.

But why does shaking make it fizz so much? Soda is filled with dissolved carbon

dioxide gas that's what makes it bubbly. When the bottle is still,

the gas stays dissolved under pressure. But shaking breaks that balance completely. Tiny imperfections on

the bottle walls act as bubble factories. Shaking spreads these bubbles throughout the

liquid. Now the CO₂ has tons of places to attach and grow.

This rapidly increases the total gas volume inside the bottle. When you open

it, the pressure suddenly drops and that trapped gas escapes instantly as foam.
