Drinks should be as cold as fresh from the fridge, but in much less time. Why does this phenomenon occur? It’s all about chemistry.

The sodium and chlorine ions in salt lower the freezing point of water well below 0°C. And when the salt is dissolved in water, an endothermic reaction is produced to absorb the energy in the form of heat, enhanced by the motion that we produce when the content is shaken. In other words, The heat of the soft drink is absorbed, and passes more quickly the cold of the ice to drink.
