- ==> real-life/icecubes.p <==
- You have an old-fashioned refrigerator with a small freezer compartment
- which could hold seven ice cube trays stacked vertically, but there are
- no shelves to separate the trays. You have an unlimited supply of trays,
- each of which can make a dozen cubes, but if you stand one on top of
- another before it's frozen, it will nest part way into it and you won't
- get full cubes from the bottom tray. So, what is the fastest way to
- make ice cubes?
-
- ==> real-life/icecubes.s <==
- By using frozen cubes as spacers to hold the trays apart, you can make
- 84 cubes in the time it takes to freeze two trays. Fill one tray,
- freeze it and remove the cubes. Place two cubes in the opposite
- corners of six trays, and fill the rest with water. Freeze all six,
- plus a seventh you put on top, at the same time.

- ==> real-life/microwave.p <==
- Every morning when I warm my milk for breakfast, I put one cup of milk
- in the microwave (which is in working order) for exactly 84 seconds. Why?
-
- ==> real-life/microwave.s <==
- When you put your cup in the microwave, the handle on the cup is
- pointing towards you. Your microwave has a revolving plate on which the
- cup is placed. After 84 seconds, the handle is again in it's initial
- position, so you can take the cup out without burning your hands.
