Making carbonated drinks by yourself requires eating citric acid, baking soda, white sugar, proper drinking water and sealed bottles.

Because baking soda reacts with citric acid to produce carbon dioxide, which can be dissolved in water to make carbonated drinks.

The manufacturing steps are as follows:

1, remove a sealed bottle, pour a certain amount of drinking water into the bottle, and add edible citric acid.

2. Add baking soda to the bottle.

3. Cover the bottle and shake it.

4. Add white sugar and shake evenly again.

5. Pour the soda in the bottle into the glass.

6. Add lemon slices to the edge of the cup, insert a straw, and a refreshing "homemade soda" will be ready. Refrigeration and reuse will be better.
