Can You Obtain Water From Milk, Vinegar & Ink?
In the everyday world there are many liquid items that people encounter on a regular basis. Many of these items contain small to large amounts of water, while a few liquid items may be oil based. Even fewer still exist as a pure compound and cannot be distilled to produce water.

Solutions
-
A solution occurs when two groups of molecules mix in equal distribution. One of the simplest examples is between sugar and water. This type of solution, where a solid is dissolved into a liquid, is very common, but two different liquids can form a solution, as can a gas and a liquid. On the other hand, a mixture occurs when the two compounds do not form an even distribution at the molecular level.
Distillation
-
Distillation, especially fractional distillation, can be used to separate liquids, including water, from a mixture or solution. Fractional distillation is the preferred method of extraction, as this process can separate substances with closely related boiling points. Fractional distillation differs only slightly from distillation in that it employs a fractionating column, where repeated distillations take place.

Result
-
Milk, which is a colloid of calcium, fat and proteins in water, and vinegar, which is a solution of two liquids (water and acetic acid) should yield some quantities of water during a distillation process. Ink, which can be either oil based or water based, will only yield water in the latter case.
