Dear Rabbi,
My daughters recently received a "glow in the dark toy,"
i.e.: a fluorescent toy. I was wondering why it would be permitted
to put the toy near a light on Shabbat to "charge" it,
as you are actually moving around electrons, causing them to 'fluoresce'
-- basically the same thing that is done with electricity?
Dear Steven,
The subject of using 'electricity' on Shabbat is very complex.
I'll try to answer your question despite the space limitations
of this column. The Halachic authorities prohibit turning-on
an electric light or completing an electrical circuit on Shabbat
for various reasons: Havara (burning) and/or Binyan
(building) and/or Bishul (cooking). These are 3 of the
"39 Melachot", 'work' activities, that are prohibited
on Shabbat.
Another interesting reason is mentioned: Molid - lit.
'giving birth' to a 'new product' on Shabbat. Obviously,
this doesn't forbid a mother to give birth on Shabbat! Molid
is quite a novel idea [as its name implies ;-) ].
I asked Rav Chaim Pinchas Scheinberg about using a glow in the
dark toy on Shabbat, and he answered that it is permitted, since
there is no violation of any category of Melacha
on Shabbat.
"Moving around electrons" is not prohibited unless it
involves a transgression of Shabbat, as in the case of an electrical
circuit. An act is prohibited on Shabbat only if it violates
one of the 39 Melachot, their derivatives, or special Rabbinical
prohibitions. If it doesn't, as in your case, then it is certainly
permitted.

We received several different versions of the following question
from Ask The Rabbi subscribers from around the globe:
With Yom Kippur just around the corner, I have a very practical
question. Does a pregnant woman need to fast on Yom Kippur?
Dear All,
A healthy, pregnant woman should fast on Yom Kippur, just as she
would on the 9th of Av and the other public fasts. Whereas, in
general, physical weakness exempts a pregnant woman from
the other public fasts, it does not exempt them on Yom Kippur.
However, a pregnant woman who is not well, either before or after
the onset of Yom Kippur, is permitted to eat if there is any danger
to life that may result from this illness or any complications
that my result from the illness. This may be determined by the
woman consulting with her physician. In fact, the woman's own
feeling and determination of her "need to eat" is usually
the most important factor.
Maintaining good health when under "stressful" circumstances
is also a consideration. There is a well known story about Rabbi
Yisrael Salanter beseeching his community to eat on Yom Kippur
during a cholera epidemic, so that the population's resistance
to the disease should not be lowered.
This is only a sketchy guideline. Please consult your doctor
and YLOR (Your Local Orthodox Rabbi) for a decision in your personal
case (or make a voice connection with a NSLOR - Not-So Local Orthodox
Rabbi - if an LOR is not available).
