Speculations on getting an Instant Cold Drink
How to create an instant cold drink an interesting question. There are probably engineers in the beverage industry working on such schemes. I do not know where to suggest finding information, but I am happy to speculate about how one might do it. I can imagine that one could have two compartments in a drink container, one with a pressurized refrigerant (like carbon dioxide or an environmentally friendly variant of freon) and one with the drink. When the drink is opened, depressurizing the refrigerant and allowing it to rapidly evaporate and vent to atmosphere could provide a cooling effect. There are certainly disadvantages to such a scheme, such as the space that the refrigerant takes up and making sure that the refrigerant is safely vented and not consumed. So maybe there there are other, better options. Perhaps information would be hard to find, since such tricks might be corporate secrets until they appear on the shelf. But I would not be surprised to find such a product some day.
