Non Electric Soda Machine

Soda machine (home appliance) A vending machine with soft drinks or other cold beverages; see also full-line vending. A soda fountain. Soda machines normally use refillable TR 214 thread gas cartridges, which are normally filled with around 300–500 grams of carbon dioxide. The water to be carbonated is filled in special pressure resistant bottles which are attached to the machine in a pressure proof way. The soda you get from a fountain is made on-the-fly when you press the dispenser tab. A pressurized carbon dioxide tank and a water pump send pressurized carbon dioxide gas and cold water to a carbonator, where it's mixed and the gas dissolves into the water.
