You have two glasses with an equal amount of juice in them. One has apple juice, the other: orange juice. You take some amount from the apple juice and put it into the
orange juice glass, then mix it up real nice. Then you take the same amount from the orange juice glass and put it into the apple juice glass, and mix it up.
This would be great with a video… I think the question you ask is which glass has more of it’s original juice now? Answer to follow.
