How do they make so many choices?
In: Technology
So I was actually at an amusement park and the representative was working on the machine and showed me how they work. So soda is a mixture of carbonated water and syrup, when you use a self serve machine at mcondalds or wherever you if you look at the soda being dispensed you’ll see the water stream and the syrup stream mixing together, this is how you get the final drink. As a side note some restaurants will play with the combination trying to bleed more profit out ie using more water and less syrup, why the same soda brand ex coke can taste different at different restaurants.
now the coke freestyle machine is the giant red box. When you open it up, you will find in the front a vast array or little cartridges, they look like movie theatre boxes of candy, each one of these little boxes is the syrup, the syrup box goes in its own little cubby hole, gets poked, and when you chose that specific flavor it sucks the syrup up and mixes it with the water, think a lot of how a printer works, in fact the cradles look very similar to where you put the ink cartridge into printers, the entire front of the machine has like 40-50 slots and cartridges, when one runs out you just pull it out and pop in a new one. they keep all the replacement cartridges in their storage rooms or wherever. there is then a tank that has the carbon dioxide to carbonate the water. same kind of deal, hook it up and it does its thing.
its really a neat and cleverly designed machine.

They have lots of small syrup pouches inside and can mix multiple ones to create flavors, ie. coca-cola + cherry for Cherry Coke, but also same cherry alone for Cherry Fanta.
soda is a mixture of Syrups (a concentrate of most of the flavors and other ingredients), water, and carbonation.
Freestyle machines mix these components with other flavor additives when it dispenses your drink.
If you want coke, you get the regular mixture of Coke syrup, C02, and water.
When you want cherry coke, you get Coke syrup, CO2, water, AND a small ammount of cherry flavoring added.
When you want vanilla cherry coke, you get Coke syrup, co2, water, AND cherry flavoring, AND vanilla flavoring.
The macihne has the exact ratios needed to produce each programmed mixture (represented to you as a button on the screen for that variation), and fills your cup with whatever mixture you’ve selected.
