How do you make soda go flat fast?

Add heat (good for bulk de-fizzing)

Pour the soda into a pan and warm it on the stove. The warmer your soda is, the less carbon dioxide it can hold. As it warms up, the CO2 is released faster and the soda becomes flat very quickly.

Why does my beer can foam when I open it?

Hydrophobins are created by a fungus that infects malt grains during the brewing process, attracting carbon-dioxide molecules within the beverage to the surface. Too many carbon-dioxide molecules at the beer's neck can cause the bottle to bubble over when it's opened, much to breweries' chagrin.

Does shaking a soda increase pressure?

Shaking the bottle does not increase air pressure but increases the pressure of the carbon dioxide gas above the liquid. Some of the co2 dissolved in the liquid is "undissolved" by shaking the bottle.

Does beer go flat if shaken?

Conclusion: These findings suggest that tapping shaken beer cans does not prevent beer loss when the container is opened. Thus, the practise of tapping a beer prior to opening is unsupported. The only apparent remedy to avoid liquid loss is to wait for bubbles to settle before opening the can.
