- The reason they don't use a piece of cucumber is obvious --
- the cucumber contains an unknown amount of radioactives, while the
- piece of laboratory-grade potassium has a known radioactivity. Also,
- a cucumber has _more_ radioactive isotopes than a smoke detector.
-
- Besides, if they put in the cucumber, they'd have to put a
- warning on it about how the cucumber will spoil in a while, and would
- be unsafe to eat, despite having once been a cucumber.
