My wife and I have noticed that something very fishey is going on with our favorite soft drinks. Whenever we open a bottle we aren't always thristy enough to finsh it right away. Like always we put the cap back on and put it in the refrig. An hour or two later when we are thirsty again we get the bottle out and open it to drink but guess what. It has already gone flat. The one that we drink the most is Coke but we have noticed it with Pepsi and others too. What gives? They never went flat that fast before. It use to stay fresh for a day ot two. Coca-Cola we deserve some answers.
