Carbonated drinks are obtained by saturating a fruit solution in water with carbon dioxide. To carry out such a procedure, carbon dioxide is required under a pressure of several atmospheres.
It is believed that this can only be done using an industrial installation or a special siphon. But in fact, having a set of simple and unpretentious items at hand, this can be done at home.
The article describes how you can prepare carbonated drinks at home using a minimum of materials and technical means.

Required products and materials
To make lemonade you will need:
- sugar
- lemon
- vinegar
- two plastic bottles (large 1.5 l, small 0.5 l)
In addition, you will need the following tools:
- drill
- hot glue gun
- drip tube
- small plastic bag
Step #1 Preparing the Lemonade Container
In a large bottle, you should draw water, almost completely filling it.
Then, using a funnel, 3-4 tbsp. spoons of sugar.
The lemon must be softened by rolling it slightly.
Next, it must be cut with a knife into two halves. After that, both halves of the lemon are squeezed into a large container.
Action #2 Fabrication of the gas exchange system
Using a drill, holes should be made in the lids with a diameter equal to the diameter of the tube from the dropper.
The tube should be inserted into the holes in each of the covers.
In both covers, the tubes are fixed with hot glue.
Then screw the cap on a large bottle.
Step #3 Loading Reagents and Assembling the Gassing Unit
Now you should start loading the reagents into a small bottle. Pour 300 ml of vinegar into a small bottle.
A bag is placed on the neck of a small bottle and a small indentation is made in it with a finger.
Gradually immersing the package into the bottle, they achieve the formation of a kind of “bag” in its upper part.
Next, 3-4 tbsp are poured into the bag. spoons of soda.
From above, the bag is loosely tied and immersed in vinegar.

Soda sinks to the bottom, but thanks to the presence of a reaction package, it is not yet with vinegar
On this, the assembly of the installation can be considered complete.
Action #4 Starting the gas plant
To start the process of gas formation, a small bottle should be shaken a little. In this case, the plastic bag will untie and the reaction of soda and vinegar will begin, leading to abundant gas separation.Through the tube, carbon dioxide will flow into a large bottle, and dissolve in lemonade.
After some time, the pressure in both bottles will exceed several atmospheres and the gas will begin to actively dissolve in the lemonade.
After the gas evolution process is over, the lemonade can be considered ready. Before opening a large bottle, shake it a little.
And pour the drink into glasses.
As an alternative to lemon juice, you can use various jams, to diversify the choice of drinks.
