If one comes to own a kiddush cup that is well under a reviis, is there a way the cup can be used for a mitzvah and not be left in a closet forever? What can be done with a kiddush cup that is too small? Because it was intended for a mitzvah I'd rather use it for a mitzvah if there is such an option. The cup in question has a capacity of 50ml, which is less than 2 fl. oz. and certainly much less that the minimum shiur for kiddush according to all shitot I know.

    You can use it as a Kebeitza measuring cup. – Double AA Apr 13 '16 at 17:30
  • It's pretty close to 50cc. As close as my measuring cup will take me, it's about 55cc. So yeah! That's an entertaining idea! – Daniel Moskovich Apr 13 '16 at 17:50
  • Could it have come from a kiddush fountain set, maybe? – Monica Cellio Apr 13 '16 at 21:26
  • Monica: No. It's not from a set. – Daniel Moskovich Apr 14 '16 at 4:34

In addition to msh210's ideas, these would be appropriate esp. if the cup is silver (or gold!):

  • Leaving inheritance for your kids is a mitzvah. So let the cup sit around for them.
  • You can either sell it and donate the money to a tzedaka or donate the cup itself to an org. (Hey! How about "Yiddishe Cups"?)

    For "donating the cup", should we be choshesh for lifnei iver? – Daniel Moskovich Apr 13 '16 at 18:05

    @DanielMoskovich If that's your concern, there's an easy solution. Explain things when you donate it. – DanF Apr 13 '16 at 18:28

    Is leaving a bigger inheritance for your kids a bigger mitzvah? I don't know why that would be the case. – Double AA Apr 14 '16 at 6:55
  • @DoubleAA Not sure what you mean by "bigger" or where you see that I either said or even implied that. – DanF Apr 14 '16 at 14:59
  • @DanF As long as he already owns 1 dollar to give as inheritance he's fulfilling that Mitzva, so why is keeping this cup a Mitzva? – Double AA Apr 14 '16 at 15:52

Because it was intended for a mitzvah I'd rather use it for a mitzvah if there is such an option.

I've never heard of such a thing, as far as I recall. I've heard that it's nice to reuse something for a mitzva if it was used for a mitzva, but not if it was merely intended for such use.

But no matter: that's what you want, that's what I'll address.

Here are some things you can do with a small cup (some of which are merely nice things to do rather than true mitzvos):

  • cup for Mayim Ahronim? These are rather small – mbloch Apr 14 '16 at 0:09
  • @mbloch, by all means post an answer. – msh210 Apr 14 '16 at 0:48
  • I was offering it as a possible addition to your answer - it wouldn't deserve one of its own – mbloch Apr 14 '16 at 4:23
  • @mbloch Many would think 50cc is too small for that – Double AA Apr 14 '16 at 6:56
