Carbonated water or soda water is the basic ingredient of most cocktails and other light beverages. For a party, hosts tend to stock up on bottled soda water for these cocktails. However, these could be quite expensive and could also lead to many empty bottles that are difficult to dispose. Unknown to most, soda water can actually be produced at home using a soda siphon. This siphon works by adding CO2 to the water with the help of soda chargers filled with CO2. These soda chargers are usually screwed on top of the soda siphon, which also features a small lever or plunger that initiates the mixture of CO2 and water, creating endless soda water for your cocktail needs.
