1. The Syrup: The sugary syrup that will become your soda is made first.
2. Carbonation: This syrup is then pumped into a tank filled with CO2 gas under high pressure. The pressure forces the CO2 to dissolve into the syrup.
3. Filling the Can: The carbonated syrup is then pumped into the can. This process is done under high pressure to keep the CO2 dissolved.
4. Sealing the Can: The can is sealed immediately to trap the CO2 inside.
5. Cooling: The cans are then cooled, which helps to keep the CO2 dissolved.
Why does the soda fizz?
When you open a soda can, the pressure inside decreases dramatically. This allows the dissolved CO2 to escape, forming bubbles, which is what makes the soda fizz. The colder the soda, the slower the CO2 escapes, which is why cold soda fizzes less.
