- After pouring yourself a nice cold glass of soda replace the cap tightly.
- Next shake the bottle for a good 10 seconds. Don’t do this if you plan on having another glass in a few minutes, only when you are done with it for the day.
- Place it back in the refrigerator.
- Next time you get the bottle out open the cap slowly and carefully to release the fiz.
- Repeat this process every time you use the bottle until it is gone.



















I have to say, it’s quite strange. Every time when you open the bottle, CO2 leaks out. If you DO shake it after closing, you’re forcing the CO2 to become unstable/agitated and build up pressure. However, every time you open it up again, that CO2 will be released. This only gives a false sense of “freshness”, because of the hiss you hear when you open it (which is the pressure buildup from the leftover CO2.
My suggestion would be not to buy sodas in large bottles if you’re not planning on drinking them right away. Instead, buy cans. It’s just the right amount for a drink or too, and the aluminum keeps the CO2 in place better than plastic.. Also, it’s environment friendly!
