comment Vehu Rachum and Selach Lanu for Maariv after Yom Kippur
What's the problem? I heard (I don't recall the source) that in general you don't hit your breast at Slach lanu avinu ki Chatanu at Maariv (Chabad maybe) but davka motzei YK you do. Even though you emerged from YK with a clean slate, the nature of humans is such that maybe you had an improper thought in those few minutes.

comment Does artificial meat grown in a petri dish have the halachic status of meat?
You could also use a mathematical/logical approach. If you start with one cell, it divides into two, and you have two cells with the same status as the original. Thus you can never get to a stage of nullification. Presumably this is similar to the basis that Rabbi Heinemann quoted above used.

comment Is it permitted to shoot an air gun on shabbos?
There could possibly be a problem of destroying a vessel by putting holes in it, but this relates to the target, not the weapon. There is also judaism.stackexchange.com/questions/12605/… which could be relevant.

comment Chopping items makes them Kitniyoth?
@SethJ - Don't worry. I'm sure someone will be so machmir that they will try.:-)

comment Chopping items makes them Kitniyoth?
@SethJ I don't have a source, but I seem to remember having come across the idea somewhere since there is a suspicion that, without supervision, forbidden items could have got in, accidentally or deliberately. Not only that but yisi.org/yom_tov_schedule/… suggests that they do not need supervision (but pecans do). This is counterintuitive since the same grinder could have been used for peanuts (or even actual chametz) previously and not fully cleaned - just as with many other products. If anyone can find a source either way it would be a help.

comment Chopping items makes them Kitniyoth?
Walnuts are not kitniot, but once they're chopped, it is hard to distinguish them from anything else which my be kitniot. Presumably that's why the proviso was added, in case someone bought chopped walnuts without realizing that they needed a hechsher.

comment What do people need when sitting shiva?
@DoubleAA I suspect that there are varied opinions, but in general, if something is less than the shiur, it doesn't count. msh210 - Of course it's up to each individual to decide how much he puts in.

comment What do people need when sitting shiva?
@Double AA - As I understand it the minimum amount (shiur) for tzedakah is one prutah, so less than that does not count as a charity donation.

comment What do people need when sitting shiva?
@Double AA I saw somewhere (can't remember where) that the minimum of 1 prutah translates to about 80 agorot - 0.80 shekel. I rounded it up.
