How about: upend the barrel on top of the 2 jugs? You'll have put the water in the barrel, and the jugs won't have moved so you'll still know which jug contains which water portion.Water Question.
You have two plastic jugs filled with water and a barrel. How could you put all of this water into the barrel, without using the jugs or any dividers, and still tell which water came from which jug?
