You want to rinse the milk from the one glass using the water from the other. You can dump out the milk, but a film of milk remains. In fact, each time you dump out the glass a small (but constant) amount of milk (or milk/water mixture) remains in it. What is the best strategy for rinsing the glass? Note that best implies minimum amount of milk left in the glass. Assume that each time water is poured into the milk glass the contents are stirred into homogeneity. If you wish, assume that the water glass will empty completely, so that you can use the full amount of rinse water. Or not, as you prefer.
