Can I still drink when I open the lid of 7-up?
Of course. 7-up is a carbonated drink, and it still smells when the lid is opened, which means it is a fresh drink and you can drink it without staying overnight. 7-up beverage ingredients: water, fructose syrup, white sugar, food additives (carbon dioxide, citric acid, food essence, sodium citrate, sodium benzoate, acesulfame K, sucralose). The price is 4 yuan a bottle, which can be bought in the supermarket.
