comment How should a tallit gadol be washed?
As far as I know the best way is a delicate hand wash in cold water with a careful drying procedure. I would think that dry cleaning could be OK but there could be a problem with the tzitziot in the machines.

comment Making a Bracha on pleasurable things
This seems to lead to another question - Does a Bracha have to be a formally formatted thing or is it sufficient to say (for example) "Thank G-d that I can play hockey today" in order to comply with the spirit of the quotation?

comment Scraping fish with a finger nail?
Sounds like a way of checking if the fish has scales or not. If it has scales (and of course fins) is is kosher. However, the fact that it has been cut with a probably non-kosher knife is a problem.

comment Woman with 2 wombs in regards to pidyon haben
I think the OP is basing himself on the phrase "peter rechem", so there is a valid doubt.

comment Birthday Card on Shabbat
@Menachem Maybe its value (after being written) is less than a prutah? That would probably mean that there is no kinyan (acqusition) which would be a problem with a present of value.

comment Kashrus of Pepperidge Farm Goldfish
@Michael Most fish are relatively easy to tell if they are kosher - both fins and scales - kosher - otherwise not.

comment Acronym for ה׳תש״ע
Anyone can make up an acronym based on the year letters. 5773 ended with a situation suited to תגע"ש and 5774 can be written שתד"ע - however, whether there is any real meaning to this only Hashem knows.

And if so, does it have to be cash or can it be a credit card or cheque (delayed payment)?

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.
