Why does tonic water go flat so easily?
I have a question about tonic water. Why does it go flat so easily? Even if you just open the bottle and don't use it for a day, it loses its fizz.
Tonic water contains carbon dioxide, which is what gives it those bubbles and that fizziness. However, carbon dioxide is also a gas that can escape into the air easily. That's why once tonic water is exposed to air, the carbon dioxide starts to escape and the drink goes flat.
