How to make juice sodas

Tools and materials?

Plastic cola bottles, scales.?

Citric acid, baking soda, salt, sugar, fruit juice, cold boiled water.?

Procedure of the activity?

1, take a clean plastic Coke bottle, add the appropriate amount of sugar (or salt), fruit juice, 1.5 grams of baking soda, cold water (do not fill the bottle too full) and 1.5 grams of citric acid immediately after the cap is screwed on to prevent the soda from rushing out.?
