What each ingredient does
- Bicarbonate of soda
- Reacts with the acid to release carbon dioxide, which makes the water fizz.
- Tartaric acid or citric acid
- Reacts with the bicarbonate to release carbon dioxide and gives the drink a sour taste.
The step that matters
Mix the two solutions and drink immediately. The reaction releases carbon dioxide quickly, and the fizz escapes from the glass as it stands, so the drink is best consumed right after mixing.
