You have an old-fashioned refrigerator with a small freezer compartment capable of holding seven ice cube trays stacked vertically. But there are no shelves to separate the trays, and if you stack one tray on top of another before the ice cubes in the bottom tray are fully frozen, the top tray will nestle into it, and you won't get full cubes in the bottom tray. You have an unlimited supply of trays, each of which can make a dozen cubes.

What's the fastest way to make full-sized ice cubes?

(In reply to Wrong answer by Mr. Spock)

My guess is the freezer will just barely fit the ice trays, so they can't be stacked in any way (like an alternating patern) by atlternating every other row.

I don't know if putting them at right angles is not allowed, but would imagine the ice cubes wouldn't be full size in some instances of this.

I also think the goal is to keep the trays intact, and not cut them apart. Otherwise this would be an easy problem.
