Chill a Beverage Can Quickly. REUSABLE Method.

I have seen many times on the web and on Youtube how to chill a soft drink can or bottle quickly melting some ice with salt. This mixture is known as a cooling bath and is used in chemistry to get instant cooling or  a constant temperature.

But it is a mess to make all this in order to drink a can that we forgot outside the refrigerator so I propose this alternative method.

How to chill a can without using ice and without wasting salt. With this method we use salt as an antifreeze in a jar with salt water. You only have to keep the jar in the freezer and use when necessary. After that you can put the jar in the freezer again so you dont have to throw away the salt.
