Which kind of soda will spew the most?

It's not possible to say definitively which soda will "spew" the most without knowing the specific conditions. Here's why:

* "Spewing" is subjective: It depends on what you mean by "spewing." Are you talking about the amount of foam that comes out of the bottle when opened? Or the amount of liquid that spills out when shaken?

* Carbonation varies: Different sodas have different levels of carbonation. Higher carbonation means more dissolved CO2 gas, which can lead to more foam.

* Temperature matters: Cold soda holds more dissolved CO2. Warmer soda will release CO2 more readily, causing more foam and potentially "spewing."

* Shaking: Shaking a soda bottle increases the pressure and will definitely cause it to "spew" more than if it's opened normally.

To answer your question more accurately, you would need to specify:

1. What do you mean by "spewing"? (foam, liquid, etc.)

2. Which sodas are you comparing?

3. What are the conditions? (temperature, shaking, etc.)

Let me know if you can give me more specifics, and I can try to help you figure out which soda will "spew" the most!
