Sprinkle a teaspoon of baking soda into the glass, add sugar to taste, squeeze a lemon and add water. The soda is ready!
Lemon juice contains fruit acids. When they react with baking soda, carbon dioxide forms. It dissolves poorly in water, and so it is released in the form of bubbles. So our drink becomes fizzy.
