Just like a new one / Carbonated beverage containers

When we drink soda, the feeling of soda in the drink is the strongest when the bottle is full. And, the feeling weakens as the remaining drink is less than half of what was there originally.
No matter how tightly you seal the lid, the feeling of soda weakens, because the soda gas has escaped to the empty space within the bottle.
But, I want my soda drink feel as strong as a new one all the itme.
