How Much Milk is Left?

My wife made an interesting observation this week. A gallon jug of milk does not empty evenly. We did an experiment of marking the quart marks on a gallon.

Notice that the top quart takes almost half the jug. There is a lot of jug taken up by that handle.

Of course, you still shouldn't put the jug back in the fridge with less than a juice glass at the bottom, you animal.
