This is an easy way to preserve your soda bubbles for a longer period of time after the first time you have oppened it. The trick is a simple one, you add pressure to the bottle to prevent the escape of CO2 bubbles.
As Henry's law dictates:
"At a constant temperature, the amount of a given gas that dissolves in a
given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid."
Step 1: How to Do It.
1. Buy the materials needed:
- A tightening clamp
- Your favorite beverage
2. Drink a glass or two.
3. Tightly close the bottle.
4. Put the clamp on and squeeze the bottle with it.
5. Repeate the steps 2-4 when you feel like it.
Step 2: Previous Versions
As the anciant chinese saying says: It's all about the pressure! So, it does not really matter how you get the pressure in the bottle as long as it's constant.
In the first version we tied the bottle with a wire and the drink was great even after a week.
