To reduce the amount of CO2 that escapes from a bottle of carbonated beverage when you open the cap, you should
Shake the bottle vigorously before opening the cap.
Climb to the top of a tall mountain (reduced air pressure) before opening the cap.
Put the bottle in a refrigerator for several hours before opening the cap.
i havnt done this in school yet but my idea is that shaking the bottle makes the co2 float to the top, then when you open it the presure will release and the co2 with rush out
