How Do I Toivel a Keurig?

In this week’s episode, the topics discussed by Rabbi Braun include:

Public birthday parties and ayin hora

Is there a concern of ayin hora in making large public gatherings for a seventieth or eightieth birthday?Since the Korban Todah was brought with forty challos specifically so that a crowd would be invited, is publicizing Hashem’s kindness in fact the entire point of a seudas hoda’ah?Does such a seuda carry its own protection, since the kiddush shem shamayim offsets the merits that are otherwise deducted when a miracle is done for a person?What could we learn from the Rebbe’s conduct in this regard?Tevilas keilim for electric appliances

Must electric appliances be toiveled even when the label warns that immersion will ruin them, and what practical steps make it workable?If the appliance would be ruined or the water cannot reach inside, is one exempt because a mitzvah one cannot perform does not apply, or must one simply not use the utensil?Having a Jewish professional reassemble it renders it Jewish-made. What about an amateur doing so?How much weight do the various arguments for leniency carry (mechubar lekarka, plugging it in as “finishing” it, beis hastarim, not being a kli seudah, and merely being the non-Jew’s “store merchandise”), given that tevilas keilim is deoraysa?Tevilah for a Keurig machine

Is a Keurig different from other electric appliances, being a pump rather than a kli, and one that will certainly be ruined by immersion?If it’s not merely a matter of damage but genuinely impossible for the water to reach the area requiring immersion, could it be that the chiyuv of tevilah never applied at all?May one rely on giving it as a gift to a non-Jew and borrowing it back, even though it will stay in the Jew’s hands indefinitely?Since the Taz required toiveling a borrowed kli specifically because one is able to, does that imply the requirement falls away where immersion is impossible, as poskim held with very large vessels?A shiur in shul on Shabbos afternoon

Shabbos afternoon commemorates the passing of Yosef Hatzaddik, Moshe Rabbeinu, and Dovid Hamelech (the reason for Tzidkascha). If so, may one make a fixed shiur in shul between Mincha and Maariv?Does the minhag of beis hamedrash batel begin close to dark, or only close to shkiya (and not afterward, as the Ketzos Hashulchan seems to imply), and not if beginning earlier?Does the concern apply to Chassidus, Pirkei Avos, and agaddah, or only to formal nigleh classes?May one rely on the Mishnah
