A slight correction to an article mentioning the glow observed when
pulling tape off a roll and the glow observed when crunching lifesavers
in the dark.

I am fairly certain that the glow mechanisms are totally unrelated.  I
believe the tape glow is due to static electric discharges (if you look
closely you can see the jagged sparks).

On the other hand, crunching lifesavers (or smashing large sugar crystals
with a hammer) produces light via what is know as "triboluminescence".
To make a long story short, those interested should look in the Amateur
Scientist column of Scientific American (I forget the exact date, but
sometime in the last 10 months), which has an excellent description of
the phenomenom
